ABSTRACT:
A spark ignition fuel injection reciprocatory internal combustion engine with dual induction system is provided which has within a cylinder head a primary intake port passage to direct air charge into a cylinder to swirl therein and a secondary intake port passage to direct air charge into the cylinder in such a direction as to impede and reduce the swirling motion of the air charge issuing from the primary intake port passage. An intake valve, including a valve stem and a valve head, is reciprocably mounted within the cylinder head, and an annular wall or tube is fixedly positioned in a bore in the cylinder head. The primary intake port passage communicates with the exterior of this tube and the secondary intake port passage communicates with the interior of the tube. This tube extends to a position closely adjacent to, or in engagement with, the valve head of the intake valve when the valve is in the closed position. A fuel injector, mounted to the cylinder head, discharges fuel into the secondary intake port passage toward the central portion of the head and synchronization with the opening of the intake valve so that the fuel issuing from the fuel injector will impinge upon the valve head and then disperse radially outwardly toward the periphery of the valve head. An air flow sensor is provided upstream of primary and secondary throttle valves to detect the total of flow of induction air fed to the engine so that fuel is discharged at a rate proportional to the total induction air flow.
