spark plugs, commonly known as fire plugs, will function as a pulse of high-voltage piezoelectric discharge from a high-voltage lead (fire plug), which will break down the air between the electrodes of the spark plugs, generating electrical sparks to ignite the gas mix in the cylinder. The basic conditions of high performance engine: high energy stable spark, uniform mixture, high compression ratio. Cars with internal combustion engines generally use gasoline and diesel fuel. In China's car market, gasoline cars occupy a large proportion. Gasoline engines are different from diesel engines because gasoline has a higher ignition point (around 400 degrees), which requires a forced ignition to ignite the mixture. Through the discharge between the electrodes to produce sparks, gasoline engine is through the fuel and gas mixture timely combustion to generate power, but as a fuel gasoline even in a high temperature environment is difficult to spontaneous combustion, in order to make its timely combustion is necessary to use "fire" to ignite. Here the spark ignition is the "spark plug" function
