Combination Gas - Diesel engine
I posted this in another thread, but thought it deserved one of it's own. This recently appeared on the Road & Track magazine website:
"The inevitable next step stemming from gasoline direct injection is on the horizon, and it's called DiesOtto. This is the combination of the Diesel cycle and the Otto cycle (Otto is what we use in gasoline engines). Think of it as a diesel engine that uses gasoline fuel. The combination of the two requires mind-bendingly precise engine controls. In a nutshell, the system compresses the air-charge in the cylinder until it's superheated; injects gasoline into the cylinder; the mixture ignites from the heat and drives the piston. Why? Diesel fuel is dirty and the Otto cycle is thermally inefficient. The combination eliminates the weaknesses and augments the strengths from each.
Think it's crazy? Word on the street is that GM already has prototype engines destined for their next-generation trucks on the road."
