Ethanol-powered buses being tested around the world
The buses run on a blend of 95 percent ethanol and 5 percent ignition improver in a diesel engine. I haven't heard of this combination before. Scania had to modify the engines to burn ethanol, with the major drawback being that they will burn about 70 percent more ethanol than they would biodiesel. This is an improvement how?
