How does a car parking heater work?
The car fuel heater, also known as the parking heating system, is an independent auxiliary heating system on the vehicle, which can be used after the engine is turned off, or can provide auxiliary heating during driving.
Generally, it is divided into two types: water heating system and air heating system. According to the type of fuel, it can be divided into gasoline heating system and diesel heating system. Large trucks, construction machinery, etc. mostly use diesel gas heating system, and family cars are mostly used. Gasoline water heating system.
The working principle of the parking heating system is to extract a small amount of fuel from the fuel tank to the parking heater combustion chamber, and then the fuel is burned in the combustion chamber to generate heat, which heats the engine coolant or air, and then dissipates the heat to the passenger compartment through the warm air radiator. At the same time, the engine is also warmed up. In this process, the power of the battery and a certain amount of fuel will be consumed. According to the size of the heater, the amount of fuel required for one heating varies from 0.2 liters to 0.3 liters.
The parking heating system is mainly composed of intake air supply system, fuel supply system, ignition system, cooling system and control system. Its working process can be divided into five working steps: intake stage, fuel injection stage, mixing stage, ignition and combustion stage and heat exchange stage.
