ABSTRACT:
A four-cycle internal combustion engine is provided with apparatus comprising a turbine in the inlet air flow path and an extracting compressor in the exhaust gas path. Where the internal combustion engine is an automobile engine and is operating under normal cruising conditions, the manifold inlet pressure is substantially less than atmospheric pressure and incoming air drives the inlet turbine to in turn drive the compressor. The arrangement is such that the inlet air is isentropically expanded while the exhaust gas back pressure is decreased. As a consequence, the energy of compression is reduced and the overall operating temperature of the internal combustion cycle is lowered with the result that more power is delivered for a given quantity of fuel.
