Car parking heater (air heating) carbon deposit causes and cleaning methods

After carbon deposits are formed in the combustion chamber of the car parking heater (air heating/air heating), if the carbon deposits are not cleaned up in time, a large amount of deposits will be caused, which will cause the heater to fail to fire and the heater to smoke.

Causes of carbon deposition on air heaters (air heating/air heating):

There are two reasons for car parking air heaters to produce carbon deposits, that is, insufficient fuel combustion and low oil quality, of which low oil quality is the main reason.

1. Insufficient fuel combustion: When the pump fuel is greater than the demand for a long time, the fuel combustion in the combustion chamber is not fully burned and it is easy to form carbon deposits. At this time, the heater can be dry burned for 3 to 5 times without pumping fuel. If it is not alleviated, clean up carbon deposits.

2. Low oil quality: Many drivers use oil from small gas stations. These oils are low-refined and blended oils in professional terms. They are mixed with a lot of biodiesel smelted from waste oil. These low-quality oils contain more impurities. There is a lot of water, and there are more particles after combustion. Long-term accumulation will cause carbon deposits in the combustion chamber. Therefore, Yusheng Technology recommends that most drivers use high-quality fuel.


Disassemble the parking heater, first use a flat-blade screwdriver to clean the carbon deposits on the burner, combustion tube and the inner wall of the furnace, then clean the burner with a cleaning agent, and finally blow the burner with an air gun. If it is impermeable, replace the burner ; Be careful not to damage any parts in the process of disassembling the parking heater and cleaning the carbon deposits to avoid damage to the machine. Of course, you'd better choose professional technicians to operate, to prevent operating errors, resulting in product failure.
