Glow Plug

A Glow Plug is a heating device that aids in starting a diesel engine. It is a long piece of metal that has a heating element at one end. When electric current flows through the element, it heats up and emerges a glow. The heat generated by the plug is used to raise the temperature in the cylinders. Diesel engines do not need a spark plug for their ignition stroke since diesel spontaneously combusts when it comes in contact with hot pressurized air. The glow plug, when turned on, warms the engine block surrounding the cylinders.

It absorbs the heat from the piston/cylinder friction and compresses the air. If the temperature build-up in the chamber is not sufficient, then the glowing plug is turned on to heat up the mixture till the temperature is high enough to support combustion. The glow plug is also ideal to start vehicles that have been parked in cold weather or to preheat the cars to a certain temperature until enough heat has been produced to induce combustion.

If you find that your diesel engine fails to fire up when you start your car, it could be because of a damaged glow plug. You must replace the glow plug as soon as possible to ensure that your car continues to run smoothly. At Buy Auto Parts we stock a wide variety of glow plugs for every car make and model.
