With the rapid development of automobile industry and the wide application of electronic technology in automobile, the fuel economy, safety, reliability and comfort of automobile have been improved and improved. This mechanical and electrical integration also makes the overall structure of the car, working principle and the use of maintenance has undergone a fundamental change. Previous experience in maintenance were derived from the carburetor engine vehicle by mechanical linkage, its compatibility is large, even if there is a lot of coke in the system, it will not affect the normal operation of the normal working of the engine and vehicle.
However, along with the national various vehicle restrictions and regulations, and in order to improve the dynamic performance of the engine, as far as possible to meet the people’s driving needs, it is necessary to design and construct a modern automobile engine is more and more precise. Undoubtedly, in modern cars, which will bring problems such as coke as such. These are required to continue to add new maintenance knowledge, adjust the maintenance ideas, to develop the best solution.
The increase in the lubricating system of sludge, colloid and carbon, will increase the viscosity of oil, the engine is not normal lubrication, resulting in increased wear. Produced in the cooling system of silica gel, scale and other directly affects the engine cooling coke. High temperature accumulation not only makes the mechanical deformation, and the oil oxidation, premature loss of lubrication performance and so on. In short, every car, every part of the system are coke produced may produce and accumulate directly or indirectly affect the overall performance of the vehicle of coke for every part.
(1) Baotou beiben heavy truck parts coke on the door so that the solar term solar term door position changes in the engine idling, the computer will receive the error signal, calculate the amount of oil in the wrong, the vehicle fuel consumption.
(2) Baotou beiben heavy truck parts solar term door body Coke will lead to accelerated hysteresis, unstable idle speed.
(3) Baotou beiben heavy truck parts valve coke on the one hand to occupy the air space to inflate efficiency, directly affect the power of motor vehicles; on the other hand, dry coke will also adsorption gasoline molecules of combustible mixture in the destruction of the original concentration of the mixed gas, which will lead to fire, cold start difficult and the fuel consumption will increase, coke more serious so that the valve closed lax etc..
