What is the reason for the high carbon emission of trucks?

The high carbon deposition of freight cars is caused by using inferior and unqualified gasoline, idling for a long time and burning engine oil. Most of the gasoline in many small gas stations is mixed with various additives and clean oil. This oil is the main source of carbon deposition, and some additives of this oil will directly harm three-way catalysis.

Causes of more carbon deposition in diesel engines

Car carbon deposition is generally caused by the quality of gasoline, and all cars will encounter this problem, because the quality of gasoline we use is not as good as the nominal one. After 4S inspection, there is something wrong with the gasoline pump and steering gear. It is suggested to replace the filter screen of the gasoline pump first, and then clean the oil circuit, which can effectively reduce the carbon deposition in the engine.

In addition, whether the steering gear leaks oil or not is different. If it is oil leakage, it is not a big problem. You can keep using it. If it is oil leakage, it is recommended to replace the steering gear immediately, otherwise there will be great safety hazards.

The use of unqualified and mismatched engine oil is the biggest reason for the increase of engine carbon deposition. According to the different combustion efficiency, compression ratio and sealing performance, the use of engine oil will be different. For example, if the engine with poor sealing performance uses inferior engine oil, it may cause the engine oil to burn directly from the gap between the valve oil seal and the piston ring, and the combustion product is carbon deposition.
