Continously Variable Displacement Engine
ESI"s continuously variable stroke engine expands the high efficiency operating region into the area where the engine operates during normal driving. This is accomplished using a unique patented crankshaft and connecting rod system that allows the distance the pistons travel to be adjusted on an immediate and continual basis while adjusting the combustion volume to maintain the same compression ratio. The engine is essentially being "??sized"?%9D in real time to efficiently produce the necessary power and reduce many of the losses associated with a conventional drive train.
