Operating principle of parking heating

A small amount of fuel is extracted from the fuel tank to the combustion chamber of the parking heater, and then ignited by the igniter to obtain an open flame; The combustion chamber is connected with the coolant pipeline of the water tank, and the heated coolant circulates in the vehicle; After flowing through the warm air radiator, the car is heated and the engine is preheated. The whole process does not need to start the vehicle or the engine. Generally speaking, heating for 20 minutes can make the car warm, the engine can be fully preheated, and the ice and snow on the windows will be melted. Depending on the size of the heater, the amount of fuel required for heating varies from 0.2L to 0.3L.
