A heater plug, also known as a glow plug, is a component commonly used in diesel engines to aid in cold starting. Diesel engines rely on heat generated by compression to ignite the fuel, but in cold weather conditions, the temperature may be too low for spontaneous ignition. This is where the heater plug comes into play. The heater plug is typically installed in the combustion chamber of each cylinder. It consists of a heating element, usually a metal coil or a ceramic rod with a heating wire, and is connected to an electrical power source. When the engine is started, the heater plug receives an electric current, which causes it to heat up. The heat generated by the plug is then transferred to the surrounding air and the combustion chamber.
Specifications
- Material : Heater plugs are typically made of materials that can withstand high temperatures and provide efficient heating. Common materials include steel, stainless steel, or ceramic.
- Heating Element : The heating element of a heater plug can be a metal coil or a ceramic rod with a heating wire. The choice of heating element depends on factors such as the engine design and the desired heating characteristics.
- Voltage : ranges from 5 to 12 volts.
- DurabilityHeater plugs are exposed to high temperatures and harsh conditions, so they need to be durable and resistant to wear and corrosion.
