Technology Predictions for 2009

1. Windows 7 will bring tech out of the doldrums

When Microsoft delivers Windows 7 by Q3 (Quarter 3), it could catalyze the tech economy. This new OS (Operating System) will drive businesses and consumers to new PC and notebook purchases by Q4.

2. The tech industry will be the first to recover from the recession

While the real estate and auto markets will be very slow to come back, the tech industry will recover fastest and be moving forward again by Q3.

3. The unemployed will start small businesses to survive and will need PCs to make a living

Many of those laid off due to the global recession are professionals who could start specialty consulting services as well as new businesses of various types just to survive. PC technology and communications will most likely be at the heart of their new ventures.

4. Netbook sales will double in 2009

Manufacturers should sell 36 to 38 million netbooks worldwide in 2009.

5. Smart phones will gain market share

In the next 12 months, smart phones such as Apple's iPhone and the RIM BlackBerry will gain a stronger foothold in the United States and Europe. By 2015, smart phones will represent as much as 65 percent of all cell phones sold globally.

6. Android will expand its reach in 2009

By the end of 2009, Expect top see Android in set-top boxes, digital televisions, and Mobile Internet Devices (MIDs), and perhaps even desktop terminals.

In fact, Android could emerge as the biggest threat to Linux's desire to make the mainstream, and within the next three years, Android could become a major OS in its own right.

7. Apple market share in PCs and smart phones will grow

Even in a downturn, Apple will grow its market share by at least 2 points in 2009. The ease-of-use message and the complete ecosystem are attracting more new customers to Apple stores, and the company will gain new Mac users at the expense of Windows vendors.

Also, Apple will continue to innovate around the iPhone and even add some models at lower prices to attract new customers worldwide.

8. Microsoft makes a play to purchase RIM
If the Apple iPhone makes any serious inroads into the enterprise, Microsoft will make a bid for RIM (Research in Motion) and use it to enhance and solidify the company's enterprise smart phone position.

Top 10 technology breakthroughs of 2008

1. Apple's App Store

Apple's App Store has made creating and distributing mobile applications for cellphone users easy - jumpstarting the mobile-app development market and creating clones such as the Android Market.

It even forced Research in Motion to offer a BlackBerry Application Storefront.

2. Android

The T-Mobile HTC G1 phone scores with its operating system, Android, the free mobile operating system from Google. It's the first mobile OS to make its debut in years and the G1 is just the first of what will be many phones that use it.

3. USB 3.0

USB 3.0 will be 10 times faster than the current USB 2.0 standard, and will increase the amount of electrical current that can be delivered through a USB cable.

4. Video-Capable SLRs

This year, two new cameras, the Nikon D90 and the Canon 5D Mark II not only capture top-notch still images, but let the photographer shoot high-definition videos as well.

5. The Memristor

The discovery of the "memristor," or memory transistor will make it possible to develop computer systems that remember what's stored in memory when they are turned off.

That means computers that don't need to be booted up and systems that are far more energy efficient than the current crop.

6. This year, the Global Positioning System (GPS) has been used in many new technologies, from the iPhone 3G and the T-Mobile G1 to notebooks such as Fujitsu's LifeBook series.

7. Flash memory is a mainstay of most consumer electronics products, from ultralight notebooks to digital cameras and media players.

8. Speedo LZR

Speedo's new LZR swimsuit blends new materials and a dose of NASA rocket science to boost the speeds of elite swimmers -- legally.

9. Edible Chips

Soon, tiny edible chips will track when patients take their pills (or don't) and monitor the effects of the drugs they're taking. Proteus, a Redwood City, California, company, has created tiny chips out of silicon grains that, once swallowed, activate in the stomach.

The chips send a signal to an external patch that monitors vital parameters such as heart rate, temperature, state of wakefulness or body angle.

10. Flexible Displays to be a reality by 2010 or 2011

For years, researchers have worked on thin, paperlike displays that can be folded, rolled or sewn into the sleeve of your hoodie.

Flexible displays could change the way we interact with the info-universe, creating new kinds of cellphones, portable computers, e-newspapers and electronic books.

Lean production basics

In the past, man in his quest for better standard and quality of life has allowed all other consideration to take a back seat and this accelerated the process of environmental degradation and began to threaten the earth's delicate ecological balance through which life on this planet survives. All manufacturing activities necessarily generate some form of waste. The manufacturing process does not consist of 100 per cent of conversion of material and energy inputs into usable final products; some portion of the material and energy inputs inevitably ends up as wastes. When the waste generated exceeds the maximum assimilative capacity of the environment it becomes pollution. Lean productions aims at elimination of wastes thereby reducing the environmental degradation.

Lean is about doing more with less: less time, inventory, space, people and money. Lean manufacturing (also known as the Toyota production system) is in its most basic form the systematic elimination of waste, over production, waiting, transportation, inventory, motion, over-processing, defective units and the implementation of the concepts of continuous flow and customer pull. Five areas of drive Lean manufacturing / production includes cost, quality, delivery, safety and morale.

Mercedes-Benz ML320 Bluetec – Green Diesel Car

Mercedes Bluetec is diesel that is less polluting than petrol cars.

The special equipment used on the car includes a particulate emission trap as well as the oxidation catalyst. The bluetec car gets its name from the Adblue or urea tank in the rear of the car, which helps in reduction of NOx emission. Liquid urea is added into the exhaust tract and stored in the Selective Catalytic Reduction (SCR) catalyst in the form of ammonia. This ammonia combines with the nitrogen oxide released by the engine to produce harmless nitrogen.

The Adblue tank needs to be topped at service intervals.

Mercedes has a diesel Bluetec Hybrid on the way to better the performance of this vehicle on environment as well as fuel efficiency issues.

Mercedes is not selling this vehicle in India as it needs ultra-low sulphur diesel.

Machine Tool Installation or Consumption Across the World

The United States produced $3,578 million in its own machine tool factories; it brought in $4,254 million from Japan, Germany, Taiwan, et al., and it shipped out $1,660 million to customers in Mexico, Canada, China, et al. So the U.S. can be said to have consumed $6,172 million worth of products in 2007. That number, however, is down 3 percent from the previous year’s consumption.

Global output increased to $70,986 million in 2007, a percentage gain similar to that seen on the consumption side. That $71 billion, incidentally, was split into about 73 percent metalcutting machine tools including lathes and machining centers and 27 percent metalforming machine tools, such as presses.

Japan continues to lead the world in shipments of new machines, with Germany a not-so-far-behind second. Third-place producer, China, saw a tremendous surge in output last year as its domestic factories, which had been pressured by a ravenous local appetite, cranked up output more than 40 percent over the previous year. Italy, and Taiwan ar also in top ten.

The international statistics come from the 43rd “World Machine Tool Output & Consumption Survey” (“WMTO&CS”), conducted annually by Gardner Publications Inc., the publishers of Production Machining. The “WMTO&CS” measures shipments, trade and consumption from major industrialized nations.

Top ten countrie are:

This paper presents a summary of new findings on plasticity applications in metal machining, primarily covering the recent efforts on developing new slip-line models for machining with restricted contact grooved tools which involve a finite cutting edge radius. Extended application of the initially developed plane-strain, rigid-plastic slip-line fields to take account of strain, strain-rate and temperature effects is shown to provide non-unique solutions for machining with grooved tools which most commonly incorporate geometric features such as a restricted contact and a rounded cutting edge. Predictions of cutting forces, chip thickness, chip up-curl radius, temperatures and flow stresses at the primary shear zone and at the tool-chip interface, etc. are made for a range of input conditions in orthogonal machining. The practical impact of these new findings on tool-wear and cutting tool design are emphasised in this paper.

GM Focusing on Production Engineering of Fuel Cells

June 2007

GM Aligns Fuel Cell Researchers with Company's Core Engineering Organizations

DETROIT – General Motors Corp. is moving more than 500 fuel cell experts from advanced development laboratories to core engineering functions to prepare this technology for future production.

More than 400 fuel cell engineers will report to GM's Powertrain Group to begin production engineering of fuel cell systems. Another 100 will transfer to GM's Global Product Development organization to start integrating fuel cells into future company vehicles.

Finally, more than 150 fuel cell scientists and program support will remain as part of GM's Research and Development center to continue advanced research in hydrogen storage, fuel cells and program commercialization.

The transition is aimed at expediting the company's efforts to produce vehicles that displace petroleum through energy diversity.

Said Larry Burns, GM Vice President, Research and Development. "Today's announcement signals another important milestone as we move fuel cell vehicles closer to future production."

GM shared details about its fifth-generation fuel cell system technology when it unveiled the fuel cell-powered E-Flex version of the Chevrolet Volt at the Shanghai Auto Show in April. This latest system is half the size of its predecessor, yet provides the same power and performance.

GM's fourth-generation system currently powers the Chevrolet Sequel and Equinox Fuel Cell vehicles. The Sequel recently went into the record books as the first electrically-driven fuel cell vehicle to achieve more than 300 miles on one tank of hydrogen, in and out of traffic on public roads, while producing zero emissions. The Chevrolet Equinox Fuel Cell will be launched later this year as part of Project Driveway, which will place more than 100 hydrogen fuel cell vehicles with consumers in New York, Washington, D.C. and Los Angeles.

"Moving our fuel cell experts from advanced development laboratories to our core engineering organizations highlights our strong commitment to developing electrically-driven vehicles using diverse energy sources" said Tom Stephens, GM Group Vice President of Global Powertrain.

Leading the fuel cell engineering team is Dr. J. Byron McCormick, currently executive director, GM Fuel Cell Activities. He will report simultaneously to Dan Hancock, GM Powertrain Vice President, Global Engineering, and John Buttermore, GM Powertrain Vice President, Global Manufacturing. McCormick has been working on electric and fuel cell propulsion system research and development for more than 30 years. He was instrumental in the development of the EV-1 electric vehicle, and during the past 10 years, has led the GM fuel cell activities team.

This realignment is yet another initiative in GM's commitment to displace petroleum usage in the auto industry through a range of propulsion alternatives, including:

Due next year, a front-wheel-drive 2-mode Saturn Vue Green Line that is expected to deliver up to a 45-percent improvement in combined city and highway fuel economy compared with the current non-hybrid Vue, based on current federal test procedures

Plans to produce a plug-in version of the 2-mode hybrid Vue Green Line that has the potential to achieve double the fuel efficiency of any current SUV

Additionally, GM provides more vehicles that achieve 30 mpg on the highway than any other manufacturer in the U.S. market.

GM is also the first automotive member to join the U.S. Climate Action Partnership (USCAP), a group of global companies and non-governmental organizations formed to support an economy-wide, market-driven approach to reducing carbon emissions.

IIT Bombay to Spearhead Solar power Initiative

IIT-Bombay now proposes to build solar thermal power plants in India in a demonstration-cum-research facility, which would help in developing indigenous capability and serve as a national resource centre and testing facility.

The idea is to build the country’s first consortium of industries and research organisations in this area.

As a first step, DESE organised a workshop to discuss details and identify consortium partners. The workshop, sponsored by the Ministry of New and Renewable Energy, also reviewed the status of various solar thermal power routes in the Indian context.

Three approaches were decided upon — medium temperature power generation, high temperature solar tower concept and distributed (smaller range) power generation.

While IIT-Bombay is likely to take the lead in medium temperature power generation, it will facilitate the other two. The Maharashtra Energy Development Agency has also committed to support the venture and will provide the land in Maharashtra, said Banerjee, head, Department of Energy Science and Engineering (DESE), IIT-Bombay.

Ford Designed a Hydrogen Engine in 2004

Media release of Ford

DEARBORN, Mich., Sept. 13, 2004 -- Ford engineers and researchers have successfully designed a 6.8-liter V-10 engine that burns hydrogen, further strengthening the company's role as a leader in hydrogen internal combustion engine (H2 ICE) development and possibly moving the technology one step closer to production.
Powering a Ford F-350 pickup, the V-10 H-ICE follows on the heels of the 2.3-liter I-4 H-ICE previously introduced in Ford's Model U and Hydrogen Hybrid Research Vehicle (H2 RV) -- a specially built Ford Focus wagon, two of which are logging tens of thousands of test miles in southeastern Michigan.

"The V-10 H2 ICE demonstrates our ability to produce hydrogen-burning engines in varied displacements, "said Bob Natkin, group and technical leader, Ford hydrogen internal combustion engine applications. "In fact, Ford could manufacture an H2 ICE today -- in any displacement."

Aside from the lack of a hydrogen infrastructure, on-board storage looms as the largest technical hurdle. At 5,000 psi, it takes about 12 gallons of volume to contain one kilogram of hydrogen, which has the same amount of energy as one gallon of gasoline. The H2 ICE F-350 is equipped with two large 5,000 psi hydrogen storage tanks in the truck bed that hold the equivalent of eight gallons of gasoline.

"The tanks take up quite a bit of room, but we think that with 10,000 psi tanks -- which are still very safe to use -- we can reduce the space necessary," said Natkin.

Ford views hydrogen internal combustion engines as the second phase in the company's three-pronged strategy for future automotive propulsion. Sandwiched between gasoline hybrids and hydrogen fuel cell vehicles -- the latter believed to be at least 10-15 years from large-scale production – H2 ICEs offer near zero emissions, including CO2, and are considerably less expensive than fuel cells.

"A hydrogen IC engine is up to 25 percent more fuel efficient than a gasoline IC engine and emits very little carbon dioxide, which is a harmful greenhouse gas," explained Natkin. "Hydrogen-burning engines are a bridge to fuel cells and will help develop a hydrogen fueling infrastructure and ancillary technologies, such as on-board fuel storage, H2 safety technology, and dispensing technology."

Natkin says that Ford is the clear leader in H2 ICE development among OEMs in North America and believes the same is true among all global automakers.

"BMW is the only other auto manufacturer to state publicly that they are developing hydrogen engine technology, but, in my opinion, we are further along than they are, said Natkin. "'We use a combination of lean combustion and supercharging that yields improved fuel economy without sacrificing performance. BMW does not supercharge their hydrogen engine."

The H2 ICE F-350 will serve as what is called an "engineering mule" outfitted with testing equipment that allows engineers to tweak the vehicle's unique systems.

"There is a slight discernible whine of the supercharger, but the NVH team will be able to improve that," said Natkin. "Other than that, the truck performs just like a gasoline-powered F-350."

The next step is to demonstrate this technology in fleet applications in order to gain valuable real-world data on the V-10 H2 ICE. Stay tuned

Presently Ford is not in news for hydrogen cars. BMW is in news. GM and Honda are news. GM and Honda are using fuel cell route to hydrogen cars. BMW is using burning of hydrogen in an IC engine route.

Running a Gasoline Engine on Hydrogen Using Water - 1

June 2003

Running a Gasoline Engine on Hydrogen Using Water

President Bush has made a challenge to the American people to begin running our cars on hydrogen as soon as possible, and has allocated over one billion dollars for research to find out how to do that.

In a suburb of Toronto, Canada, a small company called Rothman Technologies, Inc., has in fact discovered not one but two viable methods for breaking down ordinary water into hydrogen and oxygen.

Instant Hydrogen Gas

The first process shown to us by Rothman Technologies uses water, salt, and an extremely inexpensive metal alloy. The gas that results from this process is pure hydrogen, a fuel that burns without the need for external oxygen — and gives off no pollution whatsoever.

On behalf of Spirit of Ma'at, I visited Rothman Technologies last February (2003) in order to witness first-hand what several people had told us was true: This company was running a 12-horsepower, gasoline-powered electrical generator using water as "fuel." The generator was a gasoline combustion engine exactly like the one in your car.

This engine was mounted on a lab bench in a garage area, with the door open for ventilation. On the floor were thirteen half-gallon containers linked together with tubes, all connected to a central, larger tube that ran directly to the carburetor of the motor.

In the containers was ordinary water plus an electrolyte (i.e., some type of salt).

When a piece of metal alloy was dropped into the electrolyte mixture, hydrogen instantly began to form at an amazing rate. The hydrogen gas traveled to a main tube, and from there straight to the carburetor.

We watched the motor run for twenty minutes or so (it was really cold, with the doors open in the Toronto January winter, so we decided that twenty minutes was enough "proof of concept"). This engine, using water and salt as the primary fuel, and metal alloy as a catalyst, was definitely running!

Rothman Technologies, Inc., also has another method of converting water to fuel. It's called electrolysis. This method breaks water down into Brown's gas, which also is a perfect fuel for gasoline engines,

General Motors Hydrogen Car

January 9, 2005

General Motors' latest hydrogen car prototype, called the Sequel, will be unveiled today at a press preview of the North American International Auto Show here. It is a car unlike any other and a glimpse of a possible, very different, automotive future. Most important, it runs on a hydrogen fuel cell, so its only tailpipe emission is water vapor, not the smog-forming pollutants and greenhouse gases that come out of gasoline-powered cars.

BMW Hydrogen Car

A Dedication to Cleaner Mobility
BMWs are engineered to be clean. They must embody cleanliness in the manufacturing process that brings them to life, in the design that makes them moving works of art and in the systems that power them. But some BMWs go further in this last pursuit for cleanliness. With the CleanEnergy program, BMW is bringing vehicles to the streets of the world that are powered by renewable resources.

At the heart of this initiative is a bivalent 12-cylinder engine that can run on both gasoline and liquid hydrogen. BMW has fitted a fleet of 7-series with these innovative power plants to show the world just how effective renewable fuels are and how they will change mobility forever. The Zentrum pays tribute to this technology with an exhibit featuring one of these incredible vehicles.

Honda's Hydrogen Car

July 2007

Honda readies sleek hydrogen car for sale next year

The two FCXs Honda brought to Washington D.C. for journalists to drive represent the next-generation model. Honda says it will be producing and leasing these to consumers in some quantity next year.
Honda won't say, yet, how many it will build, but it's enough that this FCX will be manufactured on an assembly line, not one-by-one as the current model is.

Honda also isn't saying how much it will cost to lease one. The two current FCXs that are being leased to consumers cost $500 a month. Since each of those cars cost about $1 million to build, Honda's clearly not making money on that deal.

It cost less than that to build the two new FCXs that now exist and, presumably, will cost even less to make the mass-produced ones. Still, hydrogen fuel cell cars are far from cheap to make no matter how you do it.

Honda is leasing the cars rather than lending them to people free of charge - as GM will be doing with a fleet of 100 hydrogen fuel cell powered Chevrolet Equinoxes later this year - because Honda wants its users to have the same expectations any customer would have of their family car.

The cars will be leased only in areas that have some hydrogen filling stations. At-home hydrogen filling devices might also be made available, Honda said.

Honda begins production of hydrogen car

Mon Jun 16, 2008

Japanese manufacturer Honda has started the first commercial production of a hydrogen-powered car.

The medium-sized four seater is called the FCX Clarity and has a top speed of 160 kilometres per hour.

The car runs on an electric motor powered by hydrogen fuel cells and only emits water vapour.

Honda will start leasing some of the cars to people living in southern California by the end of August.

Tata-ISRO team to launch hydrogen car in 2008

November 22, 2007

Automobile major Tata Motors and space agency Indian Space Research Organisation are gearing up to launch the prototype of the car that will run on hydrogen and emit a mere wispy trail of water vapour.

Nair of ISRO said that an agreement for the pilot project to see whether hydrogen can be used as fuel for automobiles had been signed and work had already commenced on the project. He said that ISRO is working with the Tatas and, if all goes well, the car will be rolled out in early 2008.

A recent survey by the World Health Organization states that at least 10 per cent of the people in India suffer from respiratory problems due to the increase in the number of automobiles in the country.

The WHO report also said that in the next 15 years, if petrol and diesel vehicles are not phased out there is every chance of an asthma epidemic breaking out in India.

The Tatas had said in 2005 that in the next three to four years, hydrogen vehicles will be rolled out on Indian roads. The group said that by 2020, at least 1 million such cars will be rolled out in the Indian market.

Delhi is better geared for introduction of hydrogen cars due to the CNG revolution that took place there. For vehicles running on CNG there would not be any major modification required as 10 per cent blend and the hydrogen could be stored in the CNG cylinder.

R & D Team at Bajaj Auto

The R&D Team Comes Of Age In 1995, when Abraham Joseph, Bajaj Auto's R&D head, put the engine of the new 4-stroke Legend on a ten-hour endurance test, it shut down after some time. When he opened the mill, Joseph saw the inside of the block and crankshaft bearings had worn out.

Today, eight years later, Joseph and his team enjoy the fact that while developing the Eterno, Honda engineers had stripped down six Legend scooters to study them.

In terms of number of people or facilities, Bajaj R&D team is not much bigger than that of any other company (it has 100 people in R&D, 400 in product engineering, and has some of the best equipment), but it is qualitatively different now. As emotional attributes (like style) gain importance over rational attributes (like fuel efficiency) for evolving customers, Rajiv Bajaj has tried to put together a team that understands them. "We have a young bunch of people, many of whom are motorcycle riders. They are crazy about bikes and understand the customers requirements as users," adds Joseph, who himself joined in 1989. There are others like Ravi Darad, Bajaj Auto's stylist who is an engineer from IIT-Bombay. Bajaj has been hiring 30-40 engineers from the best colleges in India every year.Structural changes in the organisation have also improved response time. "The cycle time for design has come down from 3-5 years to less than two years today," says Joseph. The Pulsar took 22 months to develop; the K-60 will take 21. Way to go!

Bajaj Auto unveils revolutionary DTS-Si engine

Pune, 9thAugust 2007

Bajaj Auto, has achieved another breakthrough with the launch of new ‘Digital Twin Spark - Swirl induction’ (DTS-Si) engine. The new 125cc engine with DTS-Si technology will give an amazing mileage of 109 kilometers per liter under ideal test conditions surpassing the mileage of all current 100cc motorcycles.

Designed and developed completely by ‘**Ahead’, Bajaj Auto’s R&D, the technology promises to revolutionalise the industry with India’s most fuel-efficient two-wheeler engine.

Bajaj had first dramatically improved on existing engine technology in 2003 when it launched the DTS-i (Digital Twin Spark-ignition) engine with two Spark plugs located at opposite ends of the combustion chamber (as compared to a single spark plug in conventional 4-stroke engines) to achieve faster and more efficient combustion. The DTS-i technology offered better performance, improved fuel efficiency with lower emissions and helped establish the Bajaj Pulsar and then the Bajaj Discover as leaders in their respective segments.

The DTS-i Engine can be further engineered to deliver either exceptional performance or exceptional mileage. Bajaj Auto worked on the mother DTS-i technology to design the DTS-Si engine to deliver outstanding mileage. The DTS-Si technology gives the highest possible fuel efficiency by introducing ‘Swirl induction’ to the DTS-i engine to create turbulence in order to achieve extremely efficient combustion.

The DTS-Si engine is far superior to the conventional 4-stroke engines, which dominate the 100cc segment at present. With the new DTS-Si engine the consumer now would not have to compromise between power and mileage - he gets the best of both.


In a conventional single spark plug equipped combustion chamber, the rate of combustion is slow. The spark plug situated at one end of the combustion chamber, ignites the air-fuel mixture and the ensuing flame front spreads like a slowly inflating balloon. There is an inevitable delay for this inflating balloon to reach the furthest part of the combustion chamber. Thus, the combustion is slow and inefficient.

Digital Twin Spark ignition (DTS-i system)

The Digital Twin Spark – ignition, equipped combustion chamber takes care of the slow rate of combustion in a simple but novel way. The cylinder head is equipped with two spark plugs, instead of the conventional single spark plug. By generating two sparks at either ends of the combustion chamber, (approximately 90° to the valve axis) the Air-Fuel mixture gets ignited such that, there are 2 flame fronts created and therefore a reduction in flame travel of the order of 40% is achieved. A fast rate of combustion is achieved leading to a fast rate of pressure rise. The obvious outcome of this is more torque, better fuel efficiency and lower emissions.

Digital Twin Spark – Swirl induction (DTS-Si system)

The Digital Twin Spark - ignition or DTS- i is the mother technology for the latest Digital Twin Spark – Swirl induction or DTS-Si technology.

Thanks to DTS- i, a fast rate of combustion and therefore the resulting fast rate of pressure rise is harnessed, by optimally positioning this pressure, to deliver maximum possible work and hence obtain more torque, better fuel efficiency and lower emissions.

When burning lean Air-Fuel mixtures, the two plugs provide rapid combustion, but at light loads, opportunity exists to improve the combustion further.

Combustion efficiency in lean Air-Fuel mixture conditions can be further improved by generating high turbulence in the combustion chamber.

Combustion chambers having low turbulence give rise to propagation of a flame front, which is akin to that of a gradually expanding balloon. This results in a slower rate of combustion and thus slower rate of pressure rise. End result is lower efficiency.

When high turbulence is generated and combustion takes place, the surface of the ballooning flame front fragments itself, with projection like fingers, which increases its surface area, thereby improving combustion further.

The straight ports used in conventional engines have limitations in generating high swirl values due to their geometry. One of the ways to generate more swirl is to have a port configuration that promotes this phenomena. An offset port configuration was arrived upon and optimised to generate the required swirl numbers.

Incorporated in the new engine, this results in a swirling motion of the incoming charge, which decays itself into turbulence as the piston moves in the Induction and Compression strokes. This results in the Air-Fuel mixture being more thoroughly mixed and spread around the combustion chamber. Sparks provided by the twin spark plugs ignite this highly turbulent and compressed Air-Fuel mixture, leading to a flame front with high surface area, resulting in a rapid rise of pressure due to rapid combustion. The values of turbulence achieved now, are substantially higher than that of a straight port cylinder head, such as in Pulsar. A combination of DTS-i and Swirl induction thus provides extremely rapid combustion, resulting in high efficiency.

Bajaj Auto Limited - Achievements in Research and Development

During the last few years, the company’s R&D has been able to set new trends, crack new technology platforms and develop new, segment-defining bikes.

Bajaj owes quite a bit of the success of the two bikes to its in-house R&D’s Digital Twin Spark Ignition (DTS-i) technology. DTS-i technology, was patented.

Bajaj is taking the DTS-i technology to the next level by coupling swirl induction with the digital twin spark ignition system.
The company’s well-accepted twin-spark-plug technology engine now gets offset intake ports and other changes to also incorporate swirl induction that enables better performance during lean air mixture conditions in the combustion chamber.
The DTS-Si engine is likely to be the new technology showcase for Bajaj and could find its way into many more Bajaj bikes of the future.

Potential pedal-power could aid Third World

In Rowan University's mechanical engineering department, students' project resulted in the development of a pedal-powered grain crusher. Recently, Heather Klein and Josh Bonzella, senior civil engineers, along with Kevin McGarvey, a senior mechanical engineering major, have teamed with Dr. Beena Sukumaran, a civil and environmental engineering professor to create a pedal-powered grain crusher.

The grain crusher project has been offered to students for the past three semesters, culminating in a completion of a prototype that is expected to be finished during the fall of 2008.

At present villagers either do it by hand or have to walk several miles to get it ground in a mill, where the costs are quite high. A grain crusher helps to grind any grain to flour so that folks can use it for various purposes. The grain crusher that the students have designed can crush barley, rice, wheat, and corn.
By using the crusher, the women who are grinding grain all day by hand, or walking miles away to use a community machine would get a much needed break and would be available to do other things throughout their day.

The professors are now planning to make it popular in developing countries. They said "Bigger plans are expected for the grain crusher, which includes figuring out a way to get the product to other countries. "Well I think if we can get this crusher distributed on a large scale, it will really help these people get the grain they need without straining themselves," McGarvey said. "Plus we are hoping that it will be kind of fun for kids to ride, and just give them something fun to do that is also beneficial to the community," he added.

By doing such projects, students feel as a student itself, I could actually make a difference for someone who actually needs a change in everyday life. It is quite gratifying to be able to make a difference," Bonzella said. If it is successful, the grain crusher can help produce food for residents of Third World countries and enable some people to generate an income as they travel from community to community.
