Gu Jingjing, a wonderful car in Jiyuan: How to remove carbon deposits in the car?

Generally, you can clean the throttle once every 20,000 kilometers. You need to find the throttle and remove it, then clean it with carburetor cleaner, and finally dry it with cotton cloth and put it back.

Step 2: Clean the inside of the engine.

Before you maintain and change the oil, you can pour the detergent into the old oil, let the car idle for about ten minutes, and then change the new oil.

Cleaning agents can dissolve sludge, colloid, moisture, metal chips and other deposits inside the engine.

Step 3: Clean the oil circuit.

The oil circuit includes fuel injector, combustion chamber, spark plug, throttle and other components.

Cleaning the oil circuit, what we can do ourselves is to buy fuel additives. Add fuel additives to the fuel tank before refueling. Generally, a bottle of fuel additive is enough for a 50-80 liter fuel tank.

This method can clean the carbon deposit, colloid and dirt in the oil circuit, and avoid problems such as insufficient horsepower, oil consumption, wheezing and poor acceleration. But the effect is average, but the advantage is that there is no need to disassemble parts.

General fuel additives are divided into three types: clean type, maintenance type and octane number improvement type.

Step 4: Clean the air inlet.

Buy a bottle of air intake system cleaner, pour it into special cleaning equipment, and then connect it to the air intake system for cleaning. This method can effectively clean the internal structures such as air intake and intake manifold.

This project has some shortcomings, that is, some of the cleaned carbon deposits will be discharged through the engine, and some will be intercepted by the three-way catalyst, blocking the three-way system. It is recommended to do it every 60 thousand kilometers.

In addition, higher-grade gasoline and high-speed driving can reduce carbon deposits, and the latter can even remove some carbon deposits.
