ABSTRACT:
A direct fuel-injected, multivalve, twin overhead cam shaft internal combustion engine. The fuel injector is mounted in the cylinder bore on either the intake or the exhaust side and sprays generally transversely across the diameter of the cylinder bore so as to provide stratification under at least low-speed and low-load conditions. The injector is disposed so that it is positioned below the top of the head of the piston at its top dead center position and a recess is formed in the piston head so as to clear the fuel spray and permit injection even when the piston approaches top dead center without obstruction from the piston. This recess also clears one of the valves.
