The Quality and durability of a particular system in the vehicle depends on the serviceability of each item and details in it. This also applies to the glow plugs, which perform a critical function in the operation of the engine. It depends on them starting at all temperature conditions. Therefore, the choice of this element should be treated with special attention. Select the desired item (in this case - glow plug), you should know its main principles and causes of breakdowns. 

Function and purpose of automotive glow plugs

Even at a temperature of -35 degrees Celsius, it is able to launch the petrol engine. The principle of operation of this workpiece is very simple – after starting the engine it simply ceases to function as any other functions it performs. But despite this, the car in which the glow plug (SN), it is impossible to make.

Often in many modern cars SN continue its work for two minutes after the engine is turned on. This action, in addition to stabilization of harmful emissions into the atmosphere, promotes a uniform combustion of fuel in a cold engine.

Construction Features

Glow plugs in diesel engines

Machine running on diesel fuel, can do without them, I wouldn't say the petrol cars (due to high compression at high temperatures (800-900 degrees Celsius) in the engine). But under certain circumstances a candle is significantly helps the diesel engine. In places with cold climates where the winter temperature reaches minus 40 degrees Celsius, the diesel engine cannot start. And here again come to the aid of a candle. They are by design a bit differ from gasoline counterparts. Their main difference is the presence of additional adjustable spiral. The resource of glow plug & ndash; not less than 60 thousand kilometers. After this is replaced.

Useful facts

In the distant 60-ies of the last century, the process of starting the diesel engine lasted about thirty seconds. After 20 years, this interval was reduced to 5 seconds. Now the period of engine starting is less than two seconds (about the same as the petrol engine). Goes, the glow plug is very useful!
