PRE-STARTING HEAT POWER PLANT Russian patent published in 2015 - IPC F02N19/04 F01M5/02 F02G5/02 

FIELD: power industry.

SUBSTANCE: invention can be used in pre-starting and auxiliary heat power plants of vehicles for simultaneous generation of heat and the electric power. Pre-starting heat power plant for vehicles contains an internal combustion engine (1), an electric generator (2), a waste heat exchanger (3) utilising the heat of exhaust gases, a mixing device (4) with an electric heater, a liquid pump (8) with the electric drive, a check valve (5) and hydraulic lines (9), (10), (11) with heat carrier. The plant is also contains the oil pump (15) with the electric drive, the recuperative heat exchanger (18) for heating of engine oil and the oil line which is built in the oil pan with the nozzles directed towards necks of the cranked shaft and towards the oil pump of the internal combustion engine, oil hydraulic lines. The recuperative heat exchanger (18) of heating of engine oil according to the series hydraulic circuit is connected by hydraulic lines of the heat carrier to the mixing device (4) with the electric heater. The oil pump (15) with the electric drive through oil hydraulic lines supplies engine oil to the recuperative heat exchanger (18) for heating of engine oil after which heated engine oil is supplied into the oil line which is built in the oil pan with the nozzles directed towards the necks of the cranked shaft and towards the oil pump of the internal combustion engine.

EFFECT: design simplification and reduction of dimensions.
