Cars will accumulate carbon. What are the effects of several places?

1, throttle carbon deposit: This place is the fastest place to produce carbon deposit, and it is also a place with great influence. The carbon deposit here is just some oil vapor mixed with dust and impurities in the air. At first, it was soft. After being baked by the heat of the engine, it becomes hard over time, with strong adhesion and is not easy to remove. Too much carbon deposition will lead to unstable idle speed and jitter. If it is an electronic throttle, it will be slow to respond when refueling, and some cars will rush forward when the brakes stop. It needs to be cleaned as soon as possible at this time.

2. Valve carbon deposit: There is little carbon deposit in the exhaust valve, but generally there is more carbon deposit in the intake valve, which is the same as that in the throttle valve. The higher the temperature here, the harder the carbon deposit is. If there is too much carbon deposit, if the valve is not closed properly, the power of the car will be reduced, and it will be difficult to strike a fire when the car is cold. When the car is in a cold state, part of the gasoline mixture will be absorbed by carbon deposits when it passes through the intake valve, resulting in the mixture being too thin to start the car.

3. In-cylinder carbon deposit: In-cylinder carbon deposit refers to the carbon deposit at the top of the piston, which is caused by the problem of gasoline. The gum in gasoline can't burn, and gradually deposits on the top of the piston, and hardens after high temperature combustion. Carbon deposition here will reduce the combustion chamber area, lead to power decline, cause deflagration and knock, and have a great impact on the engine.

4. Spark plug carbon deposit: The carbon deposit here is mostly due to incomplete combustion, similar to the carbon deposit in the cylinder. The spark plug is at the top of the cylinder, and the sludge impurities in the cylinder are attached to the spark plug head. Too much carbon deposit here will affect the ignition energy and combustion efficiency of spark plugs.
