Green Fuel Definitions
By Mr Ethanol | October 6, 2008
Chicago Tribune:
Tune into the green scene with Department of Energy and Environmental Protection Agency definitions:
Hybrid: These vehicles are powered by a gasoline engine and an electric motor. The gas engine is generally small and efficient. The electric motor provides additional power when needed, often during acceleration.
Ethanol: These vehicles run on an alcohol-based fuel produced from fermented corn, barley and wheat. All gasoline vehicles can run on up to 10 percent ethanol. Flexible-fuel vehicles can run on up to 85 percent. More than 1,000 filling stations around the country have ethanol blends.
Diesel or biodiesel: Internal-combustion engines that use air compression to ignite fuel to power a vehicle. Diesels are more fuel efficient than similar gas engines but have high emissions of particulates and smog-forming nitrogen oxides. New, “clean” diesel fuels will reduce these pollutants. Biodiesel is made of biodegradable vegetable oil, animal fat and recycled grease. Regular diesel is petroleum-based. More than 600 gas stations in the U.S. carry biodiesel.
Natural gas: This clean-burning fuel can be stored on board in a compressed gaseous or liquefied state. Honda makes the only dedicated nat-gas vehicle, the Civic GX, but vehicles can be retrofit to run on it. More than 700 stations in the U.S. dispense CNG.
