It seems that you are interested in spark plugs and throttle body. Spark plugs are electrical devices that produce a spark to ignite the air-fuel mixture in the combustion chamber of an internal combustion engine. ² Throttle body is a component of the air intake system that controls the amount of air flowing into the engine.
Spark plugs have three main parts: the housing, insulator, and electrodes. The housing forms an outer shell that supports the insulator and installs the spark plug in the engine. The insulator is made of a hard ceramic material that prevents high voltage from escaping from the electrodes. The electrodes are the metal parts that create the spark gap, where the spark jumps from the central electrode to the side electrode. ¹
Throttle body consists of a butterfly valve that rotates on a shaft. The butterfly valve opens and closes depending on the position of the accelerator pedal, which is connected to the throttle cable or electronic throttle control. The throttle body also has sensors that monitor the airflow and throttle position, and send signals to the engine control unit (ECU) to adjust the fuel injection and ignition timing.
Spark plugs and throttle body are important for the performance and efficiency of the engine. Spark plugs need to be replaced periodically, as they wear out over time and cause misfires, poor fuel economy, and increased emissions. Throttle body needs to be cleaned regularly, as it can get dirty from carbon deposits and cause rough idle, stalling, or hesitation. ³.
