1. The high pressure (60-70 kg / square meter) of the spark plug should be caused by mixed gas burning, so the spark plug is required to have sufficient mechanical strength.
2, spark plugs should have an insulation strength of 20,000 volts above 20,000 volts.
3, the lower part of the spark plug should be heated by 1500 ~ 2000 degrees Celsius, and it is necessary to be affected by 50 to 60 degrees Celsius, so the lower part of the spark plug must not cause knockout due to local overheating, and it is not because the spark plug temperature is too low. carbon.
4. Spark plug should be resistant to corrosion caused by fuel, lubricating oil, and combustion products of the additive.
5, spark plug should have an appropriate mounting position and electrode gap, and the sealing performance should be good.
