Higher Efficiency Engine
The efficiency of the Internal Combustion engine has not significantly increased over the last few years. Oh sure there have marginal increases, using turbo-charging but the most efficient has been diesel. That's only because a gallon of diesel has 25% more energy than a gallon of gas.
There was of course the Wankel Rotary engine which has had modest success, but the Scuderi Air Hybrid (illustrated) promises much higher efficiency- with less thermal losses through a split cycle with separate compression and combustion chambers and ignition after dead centre.
The figures quoted are 33% for 4 stroke petrol engines and 40% for Air Hybrid. This has been developed on computer (so was a Boeing 777 and it flew!) but a real engine is being built.
