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.

Every time I service a customer's diesel heater, I emphasize these points: First, check if the equipment is securely fixed—loose screws can easily cause fires. The operating sequence is crucial: start the vehicle first, then turn on the diesel heater power, and finally adjust the thermostat. Keeping it below 25 degrees saves fuel. Pay attention to the exhaust pipe position—it should face outside the vehicle for safety. Avoid mixing impurities into the fuel, as they can clog the nozzle and cause ignition failure. If you hear unusual noises, shut down immediately and inspect—most often, it's dust in the fan. I recommend cleaning the air vents after each use, checking the fuel line seals weekly, and replacing the combustion chamber filter every six months. Avoid high airflow immediately after a cold start; preheat for 5 minutes before increasing the temperature. This reduces part wear and can extend the heater's lifespan by two to three years.

I turn on the diesel heater ten minutes before leaving in the morning, so my hands won't freeze when getting in the car. The operation is quite simple—just find the diesel heater button on the center console, press it to light up, and wait for the indicator to turn green. Then, adjust the temperature knob; I usually set it to 18 degrees with the fan speed at level one for quieter and more comfortable operation. The vents can be adjusted in direction, and I aim them at my legs for warmth without feeling stuffy. Half an hour is enough for my commute, and I turn it off before getting out of the car, remembering to shut it down before turning off the engine to avoid battery drain. Using the diesel heater on rainy days also helps defog the windows much faster than the air conditioner. It's recommended to clean external dust monthly for smoother airflow. Always choose genuine parts, as off-brand ones carry a higher risk of oil leaks.

The diesel heater is fuel-efficient and safe to use. First, ensure the diesel heater is securely fixed with no items piled around it. Before starting, check the engine oil level and top it up if it's low. When operating, always start the vehicle first, then turn on the diesel heater switch and wait for the startup light to illuminate before slowly adjusting the temperature knob. I find setting it around 20 degrees Celsius to be the most economical, consuming about half a liter of fuel for half an hour of use. For short trips, avoid using it for more than 40 minutes, and for long journeys, remember to turn it off every two hours. Point the exhaust pipe away from the vehicle and crack open a window for ventilation—this is crucial. Always turn off the diesel heater before shutting down the engine to prevent excessive carbon buildup. Monthly, disassemble the casing to clean out dust, and replace the filter annually. This ensures both safety and fuel savings, keeping you warm even in sub-zero winter temperatures.
