Disadvantages of cleaning throttle valve

The disadvantages of cleaning the throttle are:

1, it is difficult to start the engine, and the dirty throttle affects the air intake, which will lead to the difficulty in starting the engine.

2. Engine idling is unstable. When idling, the opening of the throttle itself is relatively small, and an unclean throttle will take up space, which will lead to unstable intake during idling, and eventually lead to unstable engine idling (driving).

3. Engine power decreases, acceleration is weak, and fuel consumption increases: after the throttle is dirty, due to poor air intake, the concentration of combustible mixture increases and the air-fuel ratio decreases during acceleration, so that the fuel in the engine cylinder cannot be completely burned, and finally the engine power decreases, acceleration is weak, and fuel consumption increases.

4. Engine emissions exceed the standard. Due to poor air intake, the air-fuel ratio decreases, the concentration of combustible mixture increases, and it cannot be completely burned, which leads to excessive exhaust emissions.

The working condition of throttle valve directly affects the power and running condition of engine. Therefore, the throttle valve should be well checked and cleaned in time if it is dirty. If the car is equipped with a direct injection engine in the cylinder, it is mainly to clean some dust at the throttle and adopt a disassembly-free cleaning method. When the car is running off course and the acceleration is weak, it is best to quickly check the dirt on the throttle, take it apart and wash it, and then put it back together.

There are two ways to clean the throttle, one is to disassemble and the other is not to disassemble. Disassembly and cleaning the whole throttle valve from the intake pipe for cleaning; Cleaning without disassembly is a method of cleaning in the original position without disassembling the throttle valve as a whole. The biggest difference between the two is that the cleaning effect matches the cleaned throttle.
