The working principle of glow plug

The main motor of the heater drives the plunger oil pump, combustion fan and du atomizer to rotate. The fuel pump sends the inhaled fuel to the atomizer through the fuel delivery pipeline. The atomizer atomizes the fuel through centrifugal force and mixes it with the air drawn by the combustion fan in the main combustion chamber. It is ignited by the hot glow plug and fully in the after combustion chamber. After burning, it turns back and transfers heat to the coolant in the water jacket interlayer through the inner wall of the water jacket and the radiating fins above it. After heating, the medium circulates in the entire pipeline system under the action of a 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 provide instant power supply and a small amount of fuel, and to heat the circulating water of the engine through the heat generated by burning gasoline to make the engine hot start, and at the same time heat up the cab.

Product advantages of parking heater:

(1) No need to start the engine, you can preheat the engine and the interior at the same time, allowing you to open the door in the cold winter to enjoy the warmth of home.

(2) Preheating is more convenient. The advanced remote control and timing system can easily heat the car at any time, which is equivalent to having an on-board heater.

(3) Avoid wear and tear caused by cold start at low temperature. Research shows that the engine wear caused by a cold start is equivalent to a normal vehicle driving 200 kilometers, and 60% of the engine wear is caused by the cold start. Therefore, installing a parking heater can fully protect the engine and extend the service life of the engine by 30%.

(4) Solve the problems of defrosting, snow scraping and fogging of car windows.

(5) Environmentally friendly products, low emissions; low fuel consumption

(6) The service life is 10 years. One-time investment will benefit a lifetime.

(7) The structure is small and exquisite, easy to install. It is easy to maintain and can be disassembled and assembled to the new car when changing the car.

(8) In summer, it can also transport the interior of the car coolly and cool down the interior of the car to achieve multiple functions.
