Researchers at the University of Wisconsin-Madison, led by Professor Rolf Reitz have come up with an innovative solution -- an engine which blends diesel and gasoline fuels to get the best of both worlds. They have designed an engine which they say will be 20 percent more efficient than traditional gas engines, while also lowering the emissions.

....

What's more important than fuel efficiency, especially for the trucking industry, is that we are meeting the EPA's 2010 emissions regulations quite easily."

The new technology was tested on a Caterpilllar heavy duty diesel engine. It achieved a thermal efficiency of 53 percent much better than the most efficient auto diesel engines (about 45 percent) and better even than the most efficient diesel engine in the world -- a turbocharged maritime engine that is 50 percent efficient.

now, who will adapt this as a mass produced engine tech.... sounds promising

I like the opposing cylinder engine proposal posted a few days back more. It's more compact and lighter weight.

i'm not opposed to that....

just posting because it's emission/heat efficiencies are... outstanding sounding.
