The main function of the automotive distributor port sealing cover is to protect the distributor, prevent dust or foreign matter from entering the distributor, and ensure that the distributor can normally turn on and cut off the low-voltage circuit, so as to enable the ignition coil to generate high-voltage current. Specifically, through its sealing performance, the distributor port sealing cover protects the internal mechanical structure and electronic components of the distributor from the influence of the external environment to ensure the normal operation of the distributor.
In addition, the distributor port sealing cover also has the following functions:
Protecting the distributor: preventing dust, moisture or other foreign matter from entering the inside of the distributor, ensuring the long-term stable operation of the distributor.
Ensure normal connection and disconnection of low-voltage circuit: The design of the distributor port sealing cover enables the distributor to connect and disconnect the low-voltage circuit at the right time, thus triggering the ignition coil to generate high-voltage electricity to complete the ignition process.
Distribute High Voltage: According to the ignition sequence of the engine, the high voltage is distributed to the spark plugs of each cylinder to ensure that each cylinder can be ignited at the proper time.
In order to ensure the proper functioning of the distributor, it is very important to inspect and maintain the distributor port sealing cap on a regular basis. If the sealing cap is found to be damaged or deteriorated, it should be replaced in time to avoid ignition system failure caused by poor sealing, which will affect the performance and life of the engine.
