The diesel heater can be used after the engine is turned off, and it can also provide auxiliary heating during driving. Generally, it can be divided into two types: water heating system and air heating system. It can be divided into gasoline heating system and diesel heating system according to fuel types. Most large trucks and construction machinery use diesel fuel gas heating system, and family cars use gasoline hot water heating system.
The working principle of the parking heating system is to pump a small amount of fuel from the fuel tank into the combustion chamber of the parking heater, and then the fuel burns in the combustion chamber to generate heat to heat the engine coolant or air.
Then, the heat is radiated to the cabin through the warm air radiator, and the engine is preheated at the same time. In this process, it will consume battery power and a certain amount of fuel. According to the size of the heater, the amount of fuel required for one heating varies from 0.2 liters to 0.3 liters.
Parking heating system is mainly composed of air intake system, oil supply system, ignition system, cooling system and control system. Its working process can be divided into five working steps: air intake stage, oil injection stage, mixing stage, ignition combustion stage and heat exchange stage.
