A new engine concept developed by researchers at the University of Wisconsin-Madison could cut fuel consumption by about 30 percent in cars and by almost 20 percent in heavy trucks. In gas-powered cars, the new design would add little to the cost of the engine. In heavy-duty trucks, it would substantially reduce costs by eliminating the need for expensive after-treatment systems to reduce emissions.
The concept, which has been demonstrated in test engines, involves precisely mixing two different fuels in the combustion chamber, which gives greater control over both the timing and duration of combustion.
