Is it necessary to clean the car throttle?
There is no special restriction on the throttle. If the idle speed is unstable, it will be cleared. Follow the air environment of the car, the type of oil used, the interval between changing air filters, open the electronic throttle valve regularly, and connect the computer to check the throttle opening (generally free). If the opening is less than 5%, there is no need to clean it, and if it is more than 5%, clean it.
Five functions of regular valve cleaning:
1, which can effectively clean and dredge the glue and carbon deposit of the fuel nozzle and keep the fuel system clean.
2. It can clean the waste gas circulation system, reduce waste gas emission and save fuel, thus effectively protecting the oxygen sensor and the three-way catalytic conversion device.
3. It can help prevent symptoms such as knocking, unstable idle speed and poor acceleration caused by colloid and carbon deposition.
4. It can eliminate the carbon deposit on the valve seat, lubricate the valve and valve guide, improve the sealing performance, restore the cylinder pressure and increase the power.
5. It can blow off the carbon deposit in the combustion chamber, lubricate the upper area of the cylinder, reduce the wear of the piston ring and prolong the service life.

Function of throttle valve
The function of throttle is to control the intake air flow and the air entering the engine, and it is a controllable valve that determines the working condition of the engine. After the air enters the intake pipe, it is mixed with gasoline (the mixing parts of different models of cars are different) to become combustible mixture, which participates in combustion and does work. The driver controls the throttle opening by operating the accelerator pedal.
Air enters through the throttle and then mixes with gasoline to form an oil-gas mixture. The fuel injection of carburetor is to suck the gasoline in carburetor through the negative pressure formed by the airflow in the intake pipe, and then mix it and enter the cylinder. This method is extensive and unevenly distributed, which affects emissions. The EFI vehicle is an electronic signal provided by the air flow sensor and the air pressure sensor near the throttle.
