What is the purpose of cleaning the throttle body?

[VanAdrian]

Cleaning the throttle body can ensure smooth air intake, restore the vehicle's idle speed and emissions, and recover the vehicle's power. The following are specific details about the throttle body: 1. Definition: The throttle body is a controllable valve that regulates the air entering the engine. After the air enters the intake manifold, it mixes with gasoline to form a combustible mixture, which then burns to produce power. It connects to the air filter at the top and the engine block at the bottom, often referred to as the throat of the car engine. 2. Classification: There are two types of throttle bodies: the traditional cable-operated type and the electronic throttle body. In traditional engines, the throttle body operates via a cable (flexible steel wire) or linkage, connecting the accelerator pedal at one end and the throttle linkage plate at the other. The electronic throttle body primarily uses a throttle position sensor to control the opening angle of the throttle based on the engine's power demand, thereby regulating the amount of air intake.
