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
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' 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.
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 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.
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.

In order to develop indigenously mechanical engineering technology for the industries so that R&D can play a key role in self-reliance, the Central Mechanical Engineering Research Institute at Durgapur, West Bengal was established in February 1958 with the specific task of development of mechanical engineering technology.
The Central Mechanical Engineering Research Institute (CMERI) is the apex R&D institute for mechanical engineering under the aegis of the Council of Scientific and Industrial Research (CSIR ). Being the only national level research institute in this field, CMERI's mandate is to serve industry and develop mechanical engineering technology so that India's dependence on foreign collaboration is substantially reduced in strategic and economy sectors.
Besides, the institute is facilitating innovations and inventions for establishing the claims of Indian talent in international fields where Indian products shall ultimately compete.

Claim to fame: Led the team that developed the Victor, Apache, Flame and TVS Scooty, with the first variomatic engine (which does not require changing gears)
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!
Vice President (Research & Development)
Mr. Joseph started his tenure in Bajaj in July 1989 as a Graduate Trainee Engineer, took over as General Manager (R&D) in April 2005 and is currently the Vice President (R&D) since April 2007 . He is a Mechanical Engineer from the National Institute of Technology, Bhopal.
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.
DTS-Si (DIGITAL TWIN SPARK - SWIRL induction)
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.

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.
