Why is it easy for direct injection vehicles to produce carbon deposits? How can we effectively alleviate it?

Why is the car with direct injection in the cylinder most likely to produce carbon deposit? Due to the complicated structure of combustion chamber in direct injection engine, the exhaust gas generated in the crankcase of the engine cannot be discharged to the outside of the vehicle, and the exhaust gas in the crankcase forms carbon deposit, which is one of the disadvantages of direct injection engine. There are two ways to effectively alleviate this phenomenon. One way is to clean the throttle to increase the intake air inside the engine and make the combustion more complete. Second, changing the shape of the crankcase inside the engine can also effectively alleviate the generation of carbon deposits, but the cost is higher.

First, the internal transmission shaft box of the in-cylinder direct injection engine makes it easier for the engine to deposit carbon.

It is necessary to know that the engine power of direct injection in the cylinder is very strong, and the response of the owner to step on the accelerator is also very fast. However, due to design defects, the crankcase design inside the in-cylinder direct injection engine is unreasonable, and there will be a lot of unburned exhaust gas. Because the national law stipulates that this harmful gas cannot be excluded from the car, the designer left this bad luck in the crankcase inside the engine, thus forming a kind of carbon deposit.

Second, cleaning the automobile throttle can effectively alleviate the carbon deposition generated by the engine.

The automobile throttle valve is located at the air inlet at the right end of the engine and connected with the air filter element. How to alleviate the carbon deposition produced by the engine? After disassembling the throttle, the owner can use cleaning agent to remove the valve carbon deposit inside the throttle, so that air can be continuously delivered to the engine, so that the engine can burn more fully and the probability of carbon deposit is less. At the same time, the advantage of doing this is that it can enhance the engine power and reduce the fuel consumption of the car.

Thirdly, changing the shape of the crankcase inside the engine can reduce the carbon deposition of the engine.

Another way is that the owner can drive the car to a professional garage for modification, that is, change the shape of the crankcase inside the engine. Because of design defects, the crankcase is located on the left side of the combustion chamber, so it will produce a lot of harmful gases, leading to carbon deposition.
