The system would need fine-tuning for the wide-ranging cetane indices of diesel fuel found in the United States. Honda also needs to develop technology to measure emissions levels according to U.S. On-Board Diagnostic System requirements. But Japan's third-biggest automaker said it planned to roll out the advanced diesel engine in the United States within three years.
In a demonstration of other new power plant technologies, Honda also showed off a prototype of its next-generation fuel cell vehicle that runs on a newly developed compact and more powerful fuel cell stack. The new stack is designed to allow the hydrogen and water formed during electricity generation to flow vertically instead of horizontally, making the component 20 percent smaller and 30 percent lighter than the previous version. Honda's new FCX fuel-cell car now has a driving range of 354 miles--a 30 percent improvement from the 2005 model--a maximum speed of 100 miles per hour and can be driven in temperatures as low as minus 22 degrees.
