FUEL SYSTEM OF DIESEL ENGINE Russian patent published in 2007 - IPC F02M25/12 F02N17/00 

FIELD: engine engineering.

SUBSTANCE: fuel system comprises fuel tank, filter, pump, heater for preliminary heating of the engine, nozzle secured to the head of the cylinder block, activators of the Diesel fuel, fuel pipeline with by-pass line, additional by-pass line with insert shaped into a paraboloid of rotation, and control valve mounted upstream of the nozzle. The additional by-pass line is provided with a batching valve made in block with the insert secured to the block head. The outer side of the batching valve is provided with the device made of a pressure-tight shell separated by the baffle into two sections. The first section receives metal hydride, and the second section receives the pump for supplying hydrogen to the zone of injection. The baffle has a port made of a palladium alloy. The first section receives heaters mounted at the metal hydride and port. The second section receives the pump provided with the pipeline for supplying hydrogen terminated in the zone of injection of the batching valve and sealed during pauses between injections of Diesel fuel by means of a needle that is kinematically connected with the pump for supplying hydrogen to the zone of injection.

EFFECT: improved starting engine at low temperatures.
