ABSTRACT:
An auxiliary charge of air, fuel mixture, and/or recycled exhaust gas is injected into the combustion chambers of an engine through directional ports adjacent the spark plug gaps to enhance combustion, reduce noxious emissions, scavenge exhaust gases, etc. The injection timing is controlled by cam driven valves, and the magnitude thereof is regulated in accordance with both engine temperature and throttle valve opening or engine load, the latter being sensed by vacuum passages adjacent the throttle in the carburetor throat or by a direct coupling to the throttle valve.
