The production process of the preheat plug includes several steps such as casting, machining and coating. The first step is to cast the plug using a high-quality alloy material, then machine it to the desired shape and size, and finally apply a coating to the plug to protect it from corrosion and wear.

In the process of engine cold start, the preheating plug plays a crucial role. It is designed to heat the air-fuel mixture in the combustion chamber before ignition, which helps improve combustion efficiency and reduce emissions.
Here are the six key functions of the engine preheat plug:
1. Promote fuel vaporization: The preheat plug heats the air-fuel mixture, which helps vaporize the fuel and produce a more uniform mixture.
2. Reduce ignition delay: By heating the mixture, the preheat plug reduces ignition delay, which means the fuel ignites faster and more efficiently.
3. Improve cold start performance: In cold weather, the preheat plug helps the engine start more easily by providing an additional heat source.
4. Reduce emissions: Preheat plugs can help reduce emissions by promoting more complete combustion and reducing the amount of unburned fuel.
5. Improve engine efficiency: By improving combustion efficiency, preheating plugs can help improve the overall efficiency of the engine.
6. Increase engine durability: Preheat plugs can help reduce engine wear by ensuring that fuel burns cleaner and more efficiently.
