If you don't change the oil often, will there be carbon deposit?

The working principle of the engine is simply four processes: inhalation-compression-work * * *-exhaust, that is, the fuel burns in the cylinder to generate power, and then the waste generated by combustion is discharged. It seems simple, but the problem is that the short-term engine speed of the fuel in the cylinder can be understood as the speed of the crankshaft running every minute, and it can also be understood as how many times the engine injects oil and does work every minute; The normal speed of the car is about 2000 rpm, which means that the time of each fuel injection is about 0.03 seconds.

This is also a common maintenance project for car owners. Because the maintenance cost of this project is very low, ordinary maintenance personnel can do it, and the price is not cheap, so many stores promote this project for maintenance. This project can be properly cleaned for 3 kilometers, but it will become colloid under the repeated action of high temperature, and then stick to the fuel injector, engine, three-way catalyst and other positions. Once there are too many, the functions of each part will be reduced, causing problems for the car.

If there is a large amount of carbon deposit, it is recommended to clean it with walnut sand or with a professional cleaning agent. Of course, the cost is also relatively high. If the engine carbon deposit seriously affects the normal operation of the engine, it is recommended to disassemble, inspect and maintain the engine. But we must ensure its quality. If there is a lot of carbon deposit, it is necessary to disassemble the engine for mechanical polishing, and at the same time, some small tools, such as scraper, can be used to polish and clean up the carbon deposit.

Gasoline additive is a commonplace topic. In fact, as long as regular and effective fuel additives are used regularly, it can play a good role in removing carbon deposits from vehicles. Reduce the formation of carbon deposit, but if the carbon deposit is already serious, then I still suggest going to a regular 4S shop or repair shop, manually removing the throttle to clean up the carbon deposit, and then adjusting the normal parameters of the throttle and engine through the computer. This comparison effect is more significant. Can effectively clean up carbon deposits.
