Abstract
A multiple cylinder, multiple valve internal combustion engine having direct cylinder injection. The cylinder injectors are disposed on a longitudinally extending plane that contains the cylinder bore axis and are inclined at acute angles to planes perpendicular to the longitudinal plane and containing the cylinder bore axis. The spark plugs are located at the intersection of both planes and are inclined to the transverse plane similarly to the fuel injectors. An arrangement is disclosed for controlling the intake charge into the engine so as to be directed primarily on the side of the combustion chamber where the fuel injector injects under at least low speed, low load conditions.
