SYSTEM FOR HEATING AND TEMPERATURE MAINTENANCE OF HEATING MEDIUMS OF DIESEL ENGINE Russian patent published in 2015 - IPC F02N19/00 

FIELD: machine building.

SUBSTANCE: system for heating and temperature maintenance of heating mediums of diesel engine contains standard water cooling system of main diesel engine (15), water-fuel heat exchanger (27), secondary diesel-generator of low power (1), on its shaft water pump (5) is installed, it is connected with gas-water heat exchanger (3), combustion chamber (4) with atomizer (28), ignition plugs (29) and connected to fan (30). The gas-water heat exchanger (3) and water pump (5) are connected to the first circuit (14) heatsink and to water-oil heat exchanger (21), and to second circuit (23) heatsink of the standard water cooling system of the main engine (15), as well as to water-fuel heat exchanger (27) connected with the first circuit (14) heatsink. Secondary fuel tank (32) is connected with main fuel tank (38), and by fuel line (39) with the combustion chamber (4) and secondary diesel engine (1). In the fuel line (39) the electric fuel heaters (40), (46), fuel pump (42), gas fuel heater (44), connected with gas-water heat exchanger (3), fuel filter (47), solenoid valve (48) are installed. In pipelines (9), (16) connecting heatsinks of the first and second circuits (14), (23) with water pumps (55), (56) of the main engine cooling system the water gates (57), (58) are installed.

EFFECT: reduced weight and overall dimensions of the system, reduced diesel fuel flow rate.
