The car fuel heater, also known as the parking heating system, is an independent auxiliary heating system on the vehicle that can be used after turning off the engine or providing auxiliary heating during driving. It is generally divided into two types: water heating system and air heating system. According to the type of fuel, it can be further divided into gasoline heating system and diesel heating system. Large trucks, construction machinery, etc. mostly use diesel air heating system, while family cars mostly use gasoline water heating system.
The working principle of the parking heating system is to extract a small amount of fuel from the fuel tank and send it to the combustion chamber of the parking heater. The fuel then burns in the combustion chamber to generate heat, heating the engine coolant or air. The heat is then dissipated into the cabin through the heating radiator, and at the same time, the engine is also preheated. During this process, the battery power and a certain amount of fuel will be consumed. Depending on 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 mainly consists of an intake supply system, a fuel supply system, an ignition system, a cooling system, and a control system. Its working process can be divided into five steps: intake stage, fuel injection stage, mixing stage, ignition and combustion stage, and heat exchange stage.
Due to the excellent heating effect, safe and convenient use, and remote control operation of the parking heating system, the car can be preheated in advance in cold winter, greatly improving the comfort of the car. Therefore, some high-end models have become standard equipment, while in some high-altitude areas, many people are self installing it, especially in trucks and RVs used in high-latitude areas.
