FUEL SUPPLY SYSTEMS FOR FOURSTROKE INTERNAL COMBUSTION ENGINES

摘要

The system enables the supply of fuel to a four-stroke internal combustion engine comprising two pairs of cylinders in each pair of which the cycles of the two cylinders are separated by 360 DEG of rotation of the engine shaft. It includes four injection valves actuated by electromagnets controlled by an actuating device driven by a shaft at half the speed of the engine shaft. It is arranged so that each cylinder of each pair receives on each cycle two doses of fuel for periods of equal duration separated by 360 DEG of rotation of the engine shaft.
