How to Use a Diesel Heater?
2 Answers
Diesel heaters can be used directly by turning them on. Here is some relevant information about diesel heaters: 1. Working Principle: The main motor of the heater drives the plunger oil pump, combustion fan, and atomizer to rotate. The oil pump delivers the sucked fuel to the atomizer through the fuel pipeline. The atomizer atomizes the fuel through centrifugal force and mixes it with the air sucked in by the combustion fan in the main combustion chamber, where it is ignited by the hot glow plug. 2. Purpose: Mainly used for preheating the engine in winter and providing heating for truck cabins or passenger compartments. 3. Maintenance Method: After the heater has been running for a period of time, the ignition plug should be unscrewed to clean carbon deposits. If the ignition plug wire is burnt out, it should be removed and replaced with a new one. If excessive carbon deposits cause a decrease in thermal efficiency, the carbon deposits on the inner wall of the water jacket, the cooling fins, and the combustion chamber should be cleaned.
I usually drive trucks for long distances and use diesel heaters a lot in winter. There are mainly three steps: first, check if the fuel line of the diesel heater is clear and if there is diesel in the tank, then see if the exhaust pipe is blocked. Before starting, the vehicle must be running, otherwise the battery won’t be able to power the diesel heater. The second step is to operate the control panel, which usually has a power button and a temperature adjustment knob. After turning it on, wait for about ten minutes, and the warm air will come out. I usually set the temperature to around 20 degrees with medium fan speed, blowing directly towards the driver’s seat. Never fall asleep while using it; ventilation is crucial—leave a small gap in the window, otherwise, exhaust fumes can build up in the cab and cause accidents. Always remember to turn off the diesel heater before parking and shutting down the engine, otherwise, too much carbon buildup will shorten its lifespan. Also, clean the filter screen every month to extend its life—it’s a lifesaver when temperatures drop to dozens of degrees below zero in winter.
