FUEL PUMP FOR INTERNAL COMBUSTION ENGINE Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: fuel supply is batched by using a pneumatic sensor coupled with plunger of the fuel pump through inlet pipe line and gear rack. The fuel pump is provided with thread which overlaps a by-pass opening. Rotation of the plunger results in changing of active stroke and fuel supplying. The fuel pump operates impulsively and has a hydraulic drive from a pusher kinematically connected with a cam shaft. Additional correction of fuel supply is implemented by affecting the gear rack with acceleration pedal through a movable hydraulic cylinder, with an arrester of an electromagnet controlled by centrifugal relay having a drive from the cam shaft of the pump and by arresting of speed of rotation of the engine, and also with starting electromagnet coupled with the gear rack through a small rope and controlled by ignition key when starting. EFFECT: improved design. 4 cl, 1 dwg
