Buy Diesel glow plugs and repair your car affordably

Glow plug - function and leading manufacturers

Unlike a gasoline engine, the diesel engine fuel is not ignited in the combustion chamber by a spark plug. Instead, the diesel engine operates according to the principle of self-ignition, wherein fuel is injected into the heated combustion air obtained through compression and is ignited by the high temperature. In the operating state, the released heat of combustion from the previous cycle contributes to each following ignition. In the cold state of the engine, the resulting compression heat alone is not always sufficient for ignition. For this reason, diesel engines have glow plugs, which at the start of the cold engine additionally increase the temperature, thus ensuring a safe start. A glow plug is, in principle, an electric heating element which converts electric current into heat. Modern glow plugs can heat up to 1000 ° C and even more in seconds, so that the original minute-long pre-heating time, common to older diesel engines, can be reduced to a few seconds. A distinction is generally made between metal and ceramic glow plugs. The latter have a heating coil, which is enclosed by silicon nitride, and can reach very high temperatures. Known brand manufacturer of glow plugs are BOSCH, CHAMPION, NGK, BERU, VEMO, DENSO or FEBI BILSTEIN.

How long the lifespan of a glow plug normally is

Because of the aging due to constant material exposure to the high temperatures, the power of a glow plug reduces more and more leading eventually to complete failure, which reflects in poor cold starting of the engine, and extremely smoky exhaust gases. Even an unusually loud engine can be an indication of faulty glow plugs. A concrete lifespan is difficult to determine, since it is highly dependent on the usage of the glow plug and cold-start frequency. At a Bosch glow plug, the manufacturer recommends a maintenance interval of 80,000 to 100,000 kilometers. The check of a glow plug can be done means measured resistance, a high resistance (no continuity) indicates a defective glow plug.

Replacing a defective glow plug. Where can I order online cheaply?

A glow plug can be self-replaced with some skill, similar to a spark plug. The defective glow plug must be simply unscrewed with an appropriate socket and replaced after removing the plug cap .
