Glow Plug?

The fuel combustion process that takes place in a diesel engine slightly differs from the process that happens inside a petrol-powered engine. In petrol-powered engines, or engines that run on gas, spark plugs ignite fuel by using hot electric flashes. Diesel engines on the other hand, don't use hot flashes of electricity—they compress air to a point of combustibility instead. This makes it a lot more difficult to cold-start a diesel engine compared to a petrol-powered assembly. For a diesel engine to cold-start easily, it requires the presence of a specialized component called the Glow plug.

A Glow plug is an electrically-heated metal probe that warms the air and diesel mixture inside the engine's combustion chamber. Unlike spark plugs that ignite fuel and air, glow plugs don't ignite the mixture themselves; they only keep it warm. After warming up the combustion chamber, it's the piston's job to compress, and eventually ignite the diesel-air mix. The Glow plug is integral for diesel engines, especially during winter. By using glow plugs, a diesel engine is capable of warming up the engine's air supply faster. In cold weather, your diesel engine turns into a heat sink. This means your whole engine block would absorb and dissipate heat easily. So if you didn't have a Glow plug in your car, then the hot temperature brought about by compressed air would be quickly absorbed and dissipated by the engine block. As a result, you'll have a hard time starting your car.

Because of the importance of your Glow plug, it's crucial that you keep this component in shape. If it's broken, then it's time for you to start looking around for replacement glow plugs.
