Cremation plug knowledge quiz

1 What is the role of the cremation match? What is its structure?
Answer: An important part of the cremation plug pilot or system, the function is toIgnition coilsThe generated high-voltage electricity is introduced into the engine cylinder, forming a spark between its electrodes and igniting the mixture. The cremation plug is mainly composed of shell, insulator, wiring screw, wiring screw cap,GasketThe ring, center electrode, side electrode and other parts are constituted.
2What is the working environment of cremation plugs?
The working environment of cremation plugs is very harsh. The engine must withstand repeated drastic changes from normal temperature to 2000-3000 degrees; it must be able to withstand high voltage power of 20000-40000 volts; it must be able to withstand explosive power of 50 kg/cm²; it must be resistant to chemical corrosion of gasoline and gas. so,Spark plugIn the engineIgnition systemIt is not only a component with a higher failure rate, but also a component that is more easily damaged.
3Why is the ignition performance of the cremation plug very important?
The ignition performance of the cremation plug directly affectscarThe performance of the engine, if the ignition performance of the cremator plug is not good, not only will it be difficult to start, but the driving will feel fatigued, the oil and gas combustion will not be complete, the fuel consumption will increase, and a large amount of exhaust gas will be produced, which will seriously pollute the environment and will seriously affect the use of the engine. life.
4How to judge the quality of cremation plug?
For spark plugs that work normally in use, the ceramic core surface is clean, white or light brown, or there is a very thin layer of brown powdery carbon deposit on the ceramic core; the electrode is intact and gray, and the surface is not ablated; the threaded body The front end is dry and the surface is brown or brownish red.
