Honda unveils diesel system
The car maker that floored the world in the 1970s with the first gasoline engine to meet U.S. clean air guidelines without a catalytic converter said it has developed a new and simple diesel powertrain that is as clean as gasoline-fuelled cars.
The technology marks a big step forward for Honda at a time when rivals are racing to come up with ways to clear the world's strictest emissions regulations, called Tier II Bin 5, that the United States will usher in next year.
Diesel engines, which now power half of Europe's new cars, are slowly gaining traction with fuel-conscious consumers around the world since they typically get 30 percent better mileage than gasoline cars. Their weakness has been the higher exhaust levels of nitrogen oxide (NOx), a greenhouse gas.
Honda said on Monday its new diesel drivetrain features a unique method that generates and stores ammonia within a two-layer catalytic converter to turn nitrogen oxide into harmless nitrogen.
Honda engineers said the technology is superior to a process pioneered by Germany's DaimlerChrysler AG (DCXGn.DE) because the latter requires a complex system and heavy add-ons to generate ammonia from urea-based additives.
Some technical hurdles remain.
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 auto maker said it planned to roll out the advanced diesel engine in the United States within three years. DaimlerChrysler, which along with Volkswagen AG (VOWG.DE) already sells diesel cars in the world's biggest auto market, is preparing its next-generation diesel car for a 2008 launch.
"Just as we paved the way for cleaner gasoline engines, we will take the leadership in the progress of diesel engines," Honda Chief Executive Takeo Fukui told a news conference at the auto maker's R&D center north of Tokyo.
Fukui said Honda would be "open to considering" the licensing of its new diesel technology once it was perfected.
Honda has long been at the forefront of green powertrain technology, perhaps most famously with the development in 1973 of the CVCC (Compound Vortex Controlled Combustion) engine which gave the popular Civic its name.
Earlier this year, it became the first in the world to announce voluntary global carbon dioxide reduction targets for its products and production processes.
