Spark plugs are widely used in gasoline engines, typically one cylinder per cylinder, and individual high speed engines have 2 spark plugs per cylinder. The spark plug is used for introducing high-voltage electricity generated by the ignition coil into the engine cylinder, and spark is generated between gaps of the spark plug electrodes to ignite the mixed gas. The working environment of the spark plug is extremely bad, and the temperature is only 60 ℃ and the pressure is 90KPa when in the air inlet stroke of a common four-stroke gasoline engine spark plug; in ignition combustion, the temperature will rise to 3000 deg.c instantaneously and the pressure reaches 4000KPa. Spark plugs can be classified into cold type and hot type according to their heat resistance. The heat resistance of the spark plug indicates that the spark plug is to perform well at the proper temperature. Experiments prove that when the insulator of the spark plug is kept at the temperature of 500-600 ℃, oil drops falling on the insulator can be immediately burnt to form no carbon deposit, and the insulator can be pre-burned at the temperature higher than the temperature, and the carbon deposit exists at the temperature lower than the temperature. However, in the actual running process of the engine, various working conditions can appear, for example, the engine is started in an environment of minus 20 ℃, and because the engine is in a cold state, the selected heating type spark plug can not only help the engine to start quickly, but also can effectively reduce the carbon deposit quantity generated by the spark plug in the working process; however, when the engine is in high-temperature operation, the cold type spark plug is the first choice, and can rapidly lead out heat in the combustion chamber, so that the ablation and corrosion of the spark plug in a high-temperature environment are relieved, and the service life of the spark plug is effectively prolonged.
In the case of a spiral electrode spark plug of CN216902505U disclosed in chinese patent website, the installation of the spark plug can be pre-locked and reinforced, so that the spark plug can be effectively prevented from falling off due to loosening of the spark plug in the later period, however, the device cannot reduce combustion variation between cycles, and the ignition limit of mixed gas is enlarged, so that combustion is facilitated, and therefore, a device is proposed to solve the above problems.
