FUEL INJECTION ASSEMBLY FOR INTERNAL COMBUSTION ENGINE

摘要

A fuel injection assembly for an internal combustion engine comprises a pair of solenoid valves mounted on a common manifold defining a fuel supply passage which is filled with pressurized fuel at all times during operation of the engine. The solenoid valves discharge into a common chamber having a spray nozzle located at the downstream end thereof. No valve is located between the solenoid valves and the discharge end of the spray nozzle. In use, when the solenoid valves are open, the pressure drop across the solenoid valves is small with substantially the entire pressure drop associated with the assembly occurring across the nozzle. Accordingly a relatively low hold current is required by the solenoid valves.
