How much does it cost to clean up carbon deposits in 4s shops? How many parts are there to clean up carbon deposits?

Car cleaning carbon deposit cost 100-200 yuan.

1, engine combustion chamber

This is also the most important part of carbon deposit cleaning! The main position of carbon deposit is above the piston, and the carbon deposit adheres to the piston, which has a certain adsorption effect on the gasoline sprayed by the injector, so the fuel consumption may increase, and when the cold car is started, the gasoline just sprayed may be partially adsorbed by the carbon deposit, so it may be a bit difficult to start!

How to clean it: spray it directly on the piston with special cleaning equipment for a period of time, and then extract the decomposed carbon deposit and cleaning solution!

This is also the most effective way to clean up carbon deposits!

2. Throttle carbon deposition

This is also very important. Too much carbon deposition in the throttle seriously affects the idling stability and has a great impact on fuel consumption!

Fault symptoms: unstable idle speed, slow speed increase and high fuel consumption.

How to clean it: just remove it and clean it with cleaning agent. Remember that many models need to be re-matched!

3. Carbon deposition in the intake pipe

This effect is not obvious, but we must pay attention to the models that can change the intake track!

The cleaning method is to take it out and clean it, and the effect is the best. If the traditional bottle washing, the effect is minimal!

4, three-way catalytic converter carbon deposit!

This is more important. If there is too much carbon deposit here, it will directly block the three-way catalyst, resulting in poor exhaust of the engine and serious power decline! In addition, too much carbon deposition will damage the rare metals of the three-way catalyst, leading to the failure of the three-way catalyst, thus completely losing the effect of purifying the exhaust gas!
