What is the function of an automobile spark plug?
1 Answers
The function of an automobile spark plug is to introduce the high-voltage electricity generated by the ignition coil into the engine cylinder under the control of the engine, generating a spark between the electrodes of the spark plug to ignite the air-fuel mixture, enabling the engine to operate normally. The working principle of a spark plug is to introduce high-voltage electricity into the combustion chamber, causing it to jump across the electrode gap to produce a spark, thereby igniting the combustible mixture in the cylinder. An automobile spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell, with the side electrode welded to the shell. Types of spark plugs include: 1. Standard spark plug; 2. Extended insulator spark plug; 3. Electrode-type spark plug; 4. Seat-type spark plug; 5. Pole-type spark plug; 6. Surface gap spark plug.
