When most of us pull up to the pump, we are in vehicles that require gasoline. A portion of us sidle up to diesel pumps. In the future, maybe we'll we'll drive vehicles with RCCI engines and we'll ...

Five years ago we first heard about a Caterpillar diesel engine located at the University of Wisconsin-Madison, that had been modified to run on an unlikely-sounding mixture of diesel and gasoline.

Reactivity Controlled Compression Ignition (RCCI) is a style of combustion that uses two different fuels and results in a super efficient engine. Thermal efficiencies as high as about 60% have been ...

Despite gasoline and diesel fuels both being used for internal combustion, they're different enough that they require entirely different engines. You can't pull up to the pump in a diesel pickup and ...
