What is the purpose of cleaning the throttle body and fuel injectors?

[IsabelaAnn]

Cleaning the throttle body and fuel injectors helps reduce engine malfunctions and maintain optimal vehicle condition. Below is relevant information about the throttle body and fuel injectors in automobiles: 1. Throttle Body: The throttle body is a controllable valve that regulates the airflow entering the engine. After passing through the throttle body, the air mixes with gasoline in the intake manifold to form a combustible air-fuel mixture, which then ignites to generate power. 2. Fuel Injectors: A fuel injector is essentially a normally closed valve (meaning it remains shut when no control signal is received, as opposed to a normally open valve, which stays open without a control signal). Its operation is controlled by the movement of a needle valve that opens or closes the injector. When the ECU sends a fuel injection command, the voltage signal generates an electric current through the injector's coil, creating a magnetic field that lifts the needle valve, thereby opening the injector and allowing fuel to spray out through the injection nozzle.
