Function:
1. Auxiliary start: The preheating plug is installed in the preheating chamber on the upper part of the engine cylinder and under the oil injection nozzle. Before starting, the internal heat source is radiated to the surrounding oil pool through electric heating, so that the fuel reaches the predetermined temperature and becomes easier to burn
2. Reduce pollutant emissions: After the engine starts, the preheating plug can maintain a high temperature for a period of time, helping the engine to maintain a good combustion state for a period of time after starting, so that the fuel is fully burned, thereby reducing pollutant emissions.
