Development And Improvement Of Spark Plug

With the development of the automotive industry, the performance of spark plugs is also constantly improving, in order to improve the working quality of gasoline engines. For example, to improve the exhaust purification effect, wide gap spark plugs (with a gap of 1.0~1.2mm) have been adopted; To limit the noise of car radio waves, anti interference spark plugs have been developed. In the past, the service life of spark plugs was very short. Automobile manufacturers stipulated that spark plugs must be inspected or replaced after driving 3000km (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 significantly increased. Generally, after driving 10000 kilometers (or every 1 year), the spark plug must be inspected or replaced. Spark plugs with platinum electrodes have a longer service life and generally do not require inspection or replacement within 100000km of vehicle travel.
