Spark Plug Development And Improvements

With the development of the automobile industry, the performance of spark plugs is also constantly improved to improve the working quality of gasoline engines. For example, to improve the exhaust purification effect, wide gap spark plugs (gap 1.0~1.2mm) are used; to limit the noise of automobile radio waves , developed anti-interference spark plugs, etc. In the past, the service life of spark plugs was very short. Automobile manufacturers stipulated that spark plugs must be inspected or replaced after the car has traveled 3,000km (or 6 months). With the improvement of spark plugs and related ignition devices, coupled with some measures for exhaust purification, the service life of spark plugs has been greatly improved. It is generally stipulated that the spark plug must be inspected or replaced after the car has traveled 10,000km (or every one year). Spark plugs with platinum electrodes have a longer service life and generally do not need to be inspected and replaced within 100,000km of driving.
