POWER SYSTEM OF MOTOR-AND-TRACTOR DIESEL ENGINE Russian patent published in 2015 - IPC F02D19/06 F02M37/00 B60K15/06 

FIELD: machine building.

SUBSTANCE: power system of motor-and-tractor diesel engine involves fuel tanks (1, 2) for various fuels, heat exchanger (9), coarse fuel filters (11, 15), fuel backup pump (12, 16), fine fuel filters (14, 18), fuel injection pump (6), nozzle (8), fuel lines group (7), control module (19) and indicator lamps (27). Module (19) controls shut-off of thermostat (3) channels by adjusting required delivery of each fuel based on signals received from: temperature sensor (20) and fuel pressure pickup (21), coolant temperature (22), pump (6) rack (23) position, ambient air temperature (24), mode selection key (25) and controller (26) of mixture switching. Also the system is provided with mixer (5), located before pump (6) controlled by duplex four-channel thermostat (3) with hydraulic accumulator (4) located before it, additional heat exchanger (10) installed before filter (11), valves for fuel intake (13) located between filters (14) and (11), and sensor (24).

EFFECT: improving quality of motor-and-tractor diesel engine operation using bio-diesel and vegetable-based fuel, and reducing its consumption.
