BMW cranks up the efficiency of hydrogen internal combustion engines - Green Cars

BMW has been active in the development of hydrogen as an automotive fuel for many years but they have taken a distinctly different path from virtually every other automaker. Instead of fuel cells, BMW has stuck to internal combustion engines and, rather than compressed gas, it has used liquified hydrogen. The problem with the former is that gasoline and hydrogen have very different combustion characteristics and engines designed primarily for gasoline operation lose a lot of power and efficiency when running on hydrogen.

Researchers from BMW have collaborated with colleagues from HOERBIGER, the Graz University of Technology, and HyCentA to develop an engine optimized for hydrogen operation. The cylinder head is based on one from a diesel engine using similar geometry. The injection system has been replaced with a high pressure direct injection setup. The engine uses a combination of spark ignition and compression ignition to match the 42 percent efficiency of the best current turbodiesel engines. BMW plans to further improve the overall efficiency of future iterations, by utilizing the waste heat from the exhaust.

Engines based on this technology will likely appear in future hydrogen-fueled vehicles from BMW.

Will MINI build a John Cooper Works diesel? "Good Idea" - Green Cars

Click the MINI Cooper D for a high res gallery

Last summer we had a ball driving the MINI Cooper D in the ABG Garage. The torquey little 1.6-liter diesel proved to be a willing yet thrifty performer in the engine bay. While we still can’t get the MINI D in the U.S. market, BMW is reportedly considering building a high performance version of the diesel. On the gasoline-fueled side of the family, the 208 hp John Cooper Works model heads the lineup. A MINI senior engineer told AutoExpress in Geneva last week that a diesel-powered version of the JCW MINI would be a “good idea” but didn’t actually confirming anything.


Of course, we’ve heard similar claims from automaker officials many times over the years and then waited fruitlessly as nothing happened. If MINI does indeed produce a JCW diesel it would likely bump power from the current 110 hp to something in the region of 150-160 hp. Even at that level, real world mileage would likely remain somewhere in the mid-40 to 50 mpg (U.S.) range.

The BMW Hydrogen 7

BMW has announced the start of production of the new BMW Hydrogen 7, the world’s first hydrogen-powered luxury saloon car. Destined to make its first public appearance on 28 November at the Los Angeles Motor Show, the Hydrogen 7 will be built in limited numbers and offered to selected users in 2007.

The BMW Hydrogen 7 is based on the existing 7 Series and comes equipped with an internal combustion engine capable of running on liquid hydrogen or petrol. In hydrogen mode the car emits nothing more than water vapour. Powered by a 260hp 12-cylinder engine, the Hydrogen 7 accelerates from zero to 62mph in 9.5 seconds before going on to an electronically limited 143mph top speed.
