DIESEL ENGINE SUPPLY SYSTEM Russian patent published in 1998 - IPC

FIELD: mechanical engineering; diesel engines. SUBSTANCE: up to seven per cent of maximum cycle delivery of diesel fuel is fed into engine cylinder as firing dose at any operating conditions of diesel engine through fuel injection pump and nozzle according to diesel cycle. Remaining fuel in per cent to full cyclic dose is delivered through meter and mixer also at any operating conditions of diesel engine. System has fuel tank, high-pressure fuel injection pump, reducing valve on main fuel line after fuel feed pump, regulator-high pressure accelerator with control pedal and with eccentric no-load switch, engine no-load valve with no-load channel with cross section controlled by needle and with on load operation diaphragm.
