ABSTRACT:
A number of embodiments of engines having direct cylinder injection wherein the fuel injector is positioned so as to be shrouded by the piston during at least a portion of its stroke. This permits the use of less expensive and lower pressure fuel injection nozzles. The spray pattern of the injector is chosen so that some fuel is sprayed toward the spark plug to provide stratification, but the major portion is directed toward the head of the piston so to as insure a homogeneous mixture when operating at high speed, high load conditions.
