AUTOMOTIVE DIESEL FEED SYSTEM Russian patent published in 2017 - IPC F02D19/06 F02M37/00 B60K15/06 

FIELD: engines and pumps.

SUBSTANCE: automotive diesel feed system contains fuel tanks (1), fuel heater (2), coarse filters (3), fuel feed pumps (4), fine filters (5), fuel switching solenoid valve (6), fuel injection pump (7), injectors (8), control unit (16), fuel temperature sensor (17), fuel pressure sensor (20), fuel supply sensor (19). The system is provided with a recirculation system comprising an electromagnetic recirculation valve (12), an exhaust cooler (13), an adjustable damper (14) installed between the discharge (11) and intake (10) manifolds, an actuator (15), an exhaust gas temperature sensor (18) installed at the outlet of the recirculation cooler, a speed sensor (21), a flywheel (22), and a generator (23) with a combustion activator.

EFFECT: improved performance of a diesel engine operating on high-viscosity biodiesel fuels under idling, low load, at the time of starting and warming up the engine, eliminating the harmful interference of fuels on engine systems, in particular fuel ingress into the lubrication system, increased carbon formation in the cylinder piston group, reduced hazardous substances emissions with exhaust gases into the ambient air.
