Abstract
In a fuel injection system for a multi-cylinder internal combustion engine, a plurality of injection nozzles discharge fuel adjacent the engine inlet ports, and a single injector meters the fuel to all of the injection nozzles. The injector may include an annular valve surface, a plurality of discharge passages opening through the valve surface to direct fuel to the nozzles, and a single valve member associated with the valve surface to control fuel delivery to the discharge passages. The injector may include a rectifier valve that admits air to the discharge passages when the valve member precludes fuel delivery to the discharge passages. The fuel discharge lines that connect the injector discharge passages to the nozzles may be surrounded by air lines.
