HEATER STRUCTURE AND WORKING PRINCIPLE

4.1 Working Principle
After the heater is started, the glow plug plug begins to work, the fuel pump starts to supply fuel, and the combus-tion-supporting fan intakes air from outside. Fuel is burned in the combustion chamber to generate heat, which is taken away by the aluminum heat exchanger. Internal air driven by the heat exchange fan passes through the surface of the heat exchanger to carry the heat to where it is needed. The exhaust gas is discharged through the exhaust pipe.
