Throttle assembly introduce

The function of the throttle valve assembly is as follows: 1. The throttle valve of a car is a controllable valve used to control the air entering the engine. After entering the intake pipe, it mixes with gasoline (different vehicles have different mixing parts) to become a combustible mixture gas, participating in combustion and doing work. It is one of the steps to provide power for the vehicle; 2. The throttle valve is the most important component of today's electronic fuel injection vehicle engine system. Its upper part is the air filter, and the lower part is the engine block, which is the throat of the car engine and controls the vehicle's travel speed; 3. The agility of a car's acceleration is closely related to the cleanliness of the throttle valve. The owner controls the throttle valve opening by stepping on the acceleration valve to achieve the goal of slowing down)

Installation position of throttle body

The throttle body is installed at the intake manifold of the engine. The throttle body mainly includes two types: traditional cable type and electronic throttle. The traditional engine throttle control mechanism works by connecting one end to the accelerator pedal and the other end to the throttle linkage plate through a cable (soft steel wire) or rod. The electronic throttle is mainly controlled by the throttle position sensor to control the opening angle of the throttle according to the required energy of the engine, So as to adjust the size of the intake volume. The throttle valve is installed in front of the manifold and behind the hose. The throttle valve is a controllable valve that controls the air to enter the engine. After the gas enters the intake pipe, it will mix with gasoline to form a combustible mixture, which burns and does work. The phenomenon of a broken throttle valve is: 1. The engine idle is unstable, and the high idle does not decrease continuously; 2. Difficulty in starting the engine; 3. Insufficient engine power, poor acceleration performance, and unstable operation; 4. The exhaust pipe of the car emits black smoke; 5. The engine malfunction light is on. The method to clean the throttle valve is: 1. Turn off the ignition switch and remove the negative pole of the battery; 2. Remove the throttle cable, intake hose, and screws securing the throttle valve in sequence; 3. Use cleaning agent to clean the throttle valve, and wipe any areas that cannot be cleaned with cotton thread
