Abstract

The engine is provided with an auxiliary combustion chamber in its cylinder head. Near the top of the compression stroke, a cam operated valve is opened so that a portion of the mixture is admitted into the auxiliary combustion chamber. This chamber comprises a curved passage which terminates just short of the wall of the cylinder head, the passage opening into the remainder of the auxiliary combustion chamber. A cylindrical member enclosing an electrical resistance heating element projects into the passage to define a restricted area flow zone which terminates at the end of the passage.
