The reason is that: when the spark plug works for a long time, the gap between the two poles becomes larger and larger due to the spark consumption, and the required spark voltage becomes higher and higher. For a long time, the spark plug gap between the two electrodes will become larger due to high voltage discharge, so the ignition intensity will be weakened, so the spark plug gap should be adjusted. The spark plug also has a steel jacket, which allows the threaded end of the plug to be torqued into the cylinder head. Since every make and model requires a different gap size, start by looking in the owner’s manual for your vehicle to find the required gap size, or pull the information up online. However, a plug may fit hundreds of engines, from cars to golf carts. The effect of discharge gap on engine working condition is mainly the ignition loss rate. The higher the engine speed is, the bigger the ignition angle is, so the misfire rate has a great influence on the engine power output at high speed. The original spark plug is usually pre-gapped by manufacturers. 2. engine magnetic steel demagnetization. It was often caused by the excessive gap between the spark plugs.
