ABSTRACT:
There is disclosed an internal combustion engine within which is defined at least one cylinder accommodating a reciprocable piston, and within which is disposed a valve rotor mounted at the compression end of the or each said cylinder for rotation about the longitudinal axis of the cylinder and having a number of passages therethrough each extending between the cylinder interior and a portion of the structure having inlet and exhaust ports, to allow for conventional fourstroke operation with said valve rotor rotating at an appropriate fraction of crank-shaft speed, the construction being such that at top dead center following a compression stroke each passage forms a substantially independently enclosed combustion space at the compression end of the cylinder adjacent the crown of the piston. The internal contours of the passages are such as to cause a rapid swirling motion of gases admitted thereto from the ports or the cylinder and such as to propagate combustion of a fuel charge therein in a controlled and even manner when an ignition spark occurs adjacent the boundary of a combustion space remote from the piston crown after a compression stroke. Particular combustion space contours are disclosed; also phased ignition, different combustion space volumes, and different inclinations of inlet passages to direct air to the cylinder wall and an air and fuel mixture to the inner part of the cylinder. Also disclosed is throttle control means for varying the air-fuel ratio and cooling means for maintaining the surfaces of the combustion spaces at about two-thirds the temperature of the piston crown. The internal combustion engine is very suitable for an automobile powered by gasoline.
