Preventive measures for carbon deposition.
1. Domestic oil products (including gasoline and engine oil) are prone to carbon deposition.
2. The carbon deposit causes the piston ring to jam, the oil scraping performance is lost, the oil return hole is blocked, and the engine oil cannot flow back to the crankcase normally.
3, the wear between the cylinder wall and the piston, the gap is too large.
4. The corrosion and aging of the valve oil seal and crankshaft oil seal make it unnecessary to overhaul the engine oil. Many car owners have not solved the problem after overhaul, and there are other problems with their cars.
5. Try to strictly observe the engine oil model requirements in the user manual! Use high-quality engine oil to provide continuous protection for the engine.
6. Improve driving habits, avoid idling for a long time, avoid turning off the engine immediately after driving at high speed, and avoid driving at high speed immediately after starting.
7. When refueling, remember to mix different grades of gasoline. Remember not to add unqualified gasoline for a long time. You should choose a regular gas station. Sinopec's oil products come from overseas and then are distributed at home. Petrochina's oil products come from major refineries in China, which are different from each other. Don't mix Sinopec today and PetroChina tomorrow.
8, completes the maintenance, timely replacement of oil filter and air filter, etc.
Engine carbon deposits always appear in the following parts: 1, throttle. 2. Air intake pipe. 3. Valve. 4. Fuel injector. 5. Combustion chamber. 6. Three-way catalytic converter.
The general method of removing carbon deposits is to remove them. For example, the fuel nozzle of a direct injection engine can be cleaned with bottles, pipes and foam cleaning agents. Therefore, SSSS stores have different cleaning methods for different parts of vehicles, and the cost of working hours is also different.
