ABSTRACT:
A compound internal combustion engine having an efficiency materially higher than that of an engine operating on the conventional Otto or Diesel cycle. This is accomplished by using the heat of the exhaust gases to compress air, with or without the addition of fuel, which is then injected into the cylinder or cylinders of the engine just prior to ignition. In this manner, less heat is rejected from the overall cycle with improved efficiency. In the preferred embodiment of the invention, a portion of the unused heat energy in the exhaust gases is used in a unidirectional energy converter to compress air or an air/fuel mixture which is then injected into the cylinders of the engine. The engine, whether it should operate on the Otto or Diesel cycle, does not compress gas on the upstroke of the piston until the compressed gas from the unidirectional energy converter is injected into the cylinder.
