Operating principle of parking heater

The main motor of the heater drives the plunger oil pump, combustion fan and atomizer to rotate. The oil pump sends the sucked fuel oil to the atomizer through the oil pipeline. The atomizer atomizes the fuel oil through the centrifugal force and mixes it with the air sucked by the combustion fan in the main combustion chamber. It is ignited by the hot glow plug. It is fully combusted in the rear combustion chamber and then turned back. Through the inner wall of the water jacket and the upper fins, the heat is transferred to the medium in the interlayer of the water jacket - coolant. After heating, the medium circulates in the whole pipeline system under the action of circulating water pump (or thermal convection) to achieve the purpose of heating. The exhaust gas burned by the heater is discharged from the exhaust pipe.

Its working principle is to use the battery and fuel tank of the vehicle to supply power and a small amount of fuel, and heat the circulating water of the engine through the heat generated by burning gasoline, so as to make the engine hot start and raise the temperature of the cab.
