Abstract

A four stroke reciprocating piston type internal combustion engine in which an expansion ratio in each cylinder is greater than the compression ratio of the cylinder. This may be created by closing an intake valve or valves (2) of each cylinder while a piston (1) of said cylinder has travelled only part of its induction stroke, or by providing a variable restriction in the inlet system varying inversely with engine speed. In the case where closure of the intake valve or valves (2) is effected before the induction stroke is completed, the point of closure during the engine cycle is shifted from before completion of the induction stroke at lower engine speeds to after completion of the induction stroke at higher engine speeds.
