FUEL SYSTEM FOR AUTOMOBILE AND TRACTOR DIESEL ENGINES WITH INJECTION PUMP AND INJECTORS CONNECTED BY HIGH-PRESSURE PIPES AND CONTROL OF OPERATION BY CUTTING OFF FUEL DELIVERIES Russian patent published in 2007 - IPC F02D17/02 F02M59/46 

FIELD: mechanical engineering; diesel engines.

SUBSTANCE: invention relates to automatic control systems of internal combustion engines. Proposed fuel system with electronic controlled ring delivery valve for engines with control of operation by cutting off fuel delivery contains injector, high-pressure fuel injection pump with electronic controlled split ring valve and with built-in electromagnet operated by controller-regulator by signals from accelerator pedal position pickup, engine speed pickup, pickup of amount of air getting into cylinders and piston position pickup. Valve is arranged between overplunger space and low-pressure line and it controls their connection and disconnection. Bypass channel of valve is arranged opposite to ring cutout, i.e. in zone of ring shifting at minimum sliding. Ends of ring are not fastened, and ring proper is held from turning by key fitted between cutouts of ring.

EFFECT: improved reliability of control of system.
