FUEL EQUIPMENT OF DIESEL ENGINES WITH IMPROVED PERFORMANCE CHARACTERISTICS FOR PARTIAL DUTIES Russian patent published in 2004 - IPC

FIELD: mechanical engineering; internal combustion engines; fuel systems. SUBSTANCE: proposed fuel equipment contains nozzles, shutoff fuel pipeline, hydraulic lock pump, reducing valve, coarse fuel filter, fuel feed pump, fine fuel filter, high-pressure fuel-injection pump and pressure gauge. Additional valve is installed in parallel to reducing valve in hydraulic lock system. Said valve is adjusted to lower pressure and it is brought into action by means of electromagnetic valve by microswitch located on control post housing and set into operation by shaped projection on control flywheel. Solenoid is connected to control rack of high- pressure fuel-injection pump operated by electronic unit set into action by microswitch. EFFECT: reduced fuel consumption and transfer of energy at parallel operation, improved reliability and increased service life of diesel engine. 2 cl, 2 dwg
