A glow plug is a crucial component in diesel engines and some model engines. It functions like a miniature heating element, typically made of a metal alloy that can withstand high temperatures. Its primary role is to heat the combustion chamber during engine startup, aiding in igniting the air-fuel mixture by raising the temperature of the compressed air within the cylinder. This preheating process ensures reliable ignition, especially in colder conditions, enabling smooth engine operation and reducing emissions during startup.
