Glow Plug

Glow plugs are a type of heating device used in diesel engines to aid in starting the engine in cold weather conditions. They are part of the engine electrical system components in the supply class Engine Electrical System Components, Nonaircraft, which falls under the supply group Engine Accessories.

Glow plugs work by heating up the combustion chamber in the diesel engine, which helps to ignite the fuel-air mixture. This is particularly important in colder temperatures, as diesel fuel can become thicker and harder to ignite. By preheating the combustion chamber, glow plugs ensure that the engine starts smoothly and quickly.

Glow plugs are typically made of a heating element, usually a metal coil or a ceramic rod, which is encased in a protective sheath. When the engine is started, an electrical current is sent to the glow plugs, which heats up the heating element. The heat generated by the glow plugs warms up the air in the combustion chamber, making it easier for the fuel to ignite.

Glow plugs are commonly found in diesel engines used in various applications, such as cars, trucks, tractors, and other heavy machinery. They are essential components for reliable engine starting, especially in colder climates.

In summary, glow plugs are engine electrical system components that are part of the supply class Engine Electrical System Components, Nonaircraft, in the supply group Engine Accessories. They are used in diesel engines to preheat the combustion chamber and aid in starting the engine in cold weather conditions.
