How to clean up the engine carbon deposit is the most effective?

Cleaning method of engine carbon deposit;

1. Clean the throttle: remove the engine trim cover, remove the throttle, clean it with a pneumatic throttle cleaner, dry it with cotton cloth and install it.

2. Clean up the carbon deposit inside the engine: open the engine oil cover, pour in two bottles of targeted carbon deposit control liquid (mixed with old engine oil), cover the engine oil cover, and turn off the engine after ignition and idling for 60 minutes (in severe cases, the idling time can be appropriately extended). Clean the carbon deposit inside the engine. This cleaner can dissolve the deposits such as sludge, colloid, moisture and metal debris inside the engine, reduce the pollution of new engine oil and prolong the service life of the engine.

3. Clean up the carbon deposit in the oil circuit: Before refueling, add the fuel additive of the whole bottle of Ai Dong piston ring repair oil into the fuel tank. Usually, a bottle of fuel additive is used in a 50-80 liter fuel tank. Cleaning the carbon deposit in the oil circuit includes cleaning the fuel injector, combustion chamber, spark plug, throttle and other parts.

The purpose is to solve the intractable diseases such as insufficient horsepower, high oil consumption, wheezing, poor acceleration or difficult start-up caused by carbon deposit, colloid and dirt in the oil system.

4. Cleaning the carbon deposit in the air intake system: pour a bottle of cleaning agent for the air intake system into the liquid storage tank of special cleaning equipment, connect the air intake system, and suck the cleaning agent into the air intake by vacuum to achieve the cleaning purpose.

Carbon deposition is a stubborn disease of the engine, and any engine cannot avoid it. Under normal circumstances, the throttle valve and idle valve can be disassembled and cleaned regularly for the engine with injection inlet, and the carbon deposition in other parts can generally be ignored; In-cylinder direct injection engine should pay attention to the carbon deposit on the back of intake valve. If the engine power drops, the carbon deposit is serious, so it is recommended to remove it in time.

5. Dry ice cleaning. Cleaning carbon deposits with dry ice is a popular cleaning method. Because of the characteristics of dry ice, the carbon deposits can be frozen and embrittled by high-speed impact during cleaning, and the embrittled carbon deposits are easy to peel off, thus achieving the cleaning effect. This method is simple in operation, good in cleaning effect and low in cost, but it can only be used in specific situations.

6, "playing infusion bag or bottle". "Hanging a bottle" means hanging a bottle-shaped tool above the engine, pouring the cleaning agent into the engine through a conduit for cleaning, and then discharging the dirt mixture through the engine. The method is simple to operate, and the cleaning effect and cost are moderate.
