PNNL team develops onboard fuel separation technology to enable octane-on-demand for improved fuel economy

Green Car Congress

An octane-on-demand system can then meter out the appropriate fuel mixture to the engine depending on the power required: lower octane for idling, higher octane for accelerating. High-compression engines that squeeze the most work out of each drop of fuel are the engines of the future. Heldebrant, John C. Linehan, and J.
