GASOLINE INTERNAL COMBUSTION ENGINE WITH MULTI-POINT ELECTRON FUEL INJECTION Russian patent published in 1997 - IPC

FIELD: engine engineering. SUBSTANCE: each cylinder of the engine has individual nozzle 1 with ring grooves provided at both end. The grooves receive sealing rubber rings 2 and 3, which are round when they are loosened. One end of each nozzle enters the opening in boss 4 of fuel pipe line 5 secured to inlet pipe 9 of the engine. The other end of the nozzle enters the opening of inlet pipe 9 so that the rubber sealing rings of the nozzle are set in both opening mentioned above with interference. When the engine is in operation nozzle 1 is fixed against longitudinal movements by fuel pressure in fuel pipe line 5 so that the end face of rubber sealing ring 3 of nozzle 1 abuts special stop collar 12 in the opening for the nozzle of the inlet pipe. Between the end face of nozzle 1 and the bottom of the opening for the nozzle in the boss of pipe line 5 is a space. EFFECT: enhanced efficiency. 3 cl, 2 dwg
