SYSTEM OF FUEL INJECTION AND PRECOMBUSTION-CHAMBER SPRAY IGNITION IN PISTON AND ROTARY-PISTON INTERNAL COMBUSTION ENGINES

摘要

A system of fuel injection and precombustion-chamber spray ignition in piston and rotary-piston internal combustion engines is provided with a nozzle disposed in the precombustion chamber of the engine and connected to a fuel pump, and a jet pump connected to a tank filled with fuel that is provided with a device for maintaining a preset level in it. The tank and the jet pump are connected to the combustion chamber of the engine by a duct in which a shut-off valve is installed for tapping gas from the combustion chamber to the jet pump and tank, the valve having a drive functioning synchronously with the delivery of fuel by the fuel pump.
