FUEL SUPPLY SYSTEM FOR PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: system has gas a pressure regulator coupled with a gas batcher whose plunger is coupled with a tie of a controller of speed of rotation. The gas batcher is coupled with gas nozzles received in an air manifold. A high pressure fuel pump is coupled with nozzles received in cylinders of the engine. System for supplying prechamber gas is coupled with a pipe line for supplying gas through a valve and has a pressure regulator coupled with a receiver which in turn is coupled with prechambers trough check valves. The prechambers are provided with spark plugs. An assembly of throttles having effective flowing sections which are the same as effective flowing section of one throttle having diameter 1.0-1.2 mm are interposed between the receiver and check valves. EFFECT: improved design. 2 dwg
