Candles of incandescence: what are they worth knowing about?

The quality and durability of a particular system in a car depends on the health of each element and the details in it. This also applies to glow plugs, which perform the most important function in the engine operation. It is up to them to start the engine under any temperature conditions. Therefore, the choice of this element should be treated with special attention. To find the right part (in this case it's a glow plug), you need to know its basic operating principles and the causes of breakages.

Function and purpose of automotive glow plug

Even at a temperature of -35 degrees Celsius, it is able to ensure the start of the gasoline engine. The principle of operation of this part is very simple - after launching ICE, it simply ceases to function, since it does not perform any other functions. But, despite this, a car in which there is no glow plug (HF), it is impossible to start.

Often, in many modern cars, HFs continue to operate for two minutes after the engine starts. This action, in addition to stabilizing harmful emissions into the atmosphere, promotes uniform combustion of fuel in a cold engine.

Design Features

The main difference in the design of this part is that it does not understand. The driver is simply deprived of the opportunity to do anything with a broken candle. Thus, this part does not need repair, and in the event of a malfunction, it should be changed. Replacement of glow plugs takes no more than 5 minutes.

Considering the fact that these mechanisms work for a while after the engine is started, it is necessary to exclude the possibility of their overheating, and, accordingly, failure. It is worth noting that the current candles are equipped with everything necessary for long and trouble-free operation.

Glow plugs in diesel engines

Machines working on diesel fuel can do without them, which can not be said about gasoline cars (due to the high compression ratio at high temperatures (800-900 degrees Celsius) in the engine itself). But under certain circumstances, the candle significantly helps the work of the diesel engine. In places with a cold climate, where the temperature reaches minus 40 degrees Celsius in winter, the diesel engine can not be started. And then just come to the aid of candles. They are slightly different in design from their gasoline counterparts. Their main difference is the presence of an additional adjustable spiral. The life of glow plugs is not less than 60 thousand kilometers. After that, a replacement is made.

Good to know

In the distant 60s of the last century, the process of starting a diesel engine lasted about thirty seconds. After 20 years, this interval was reduced to 5 seconds. Now the period of starting the engine is not more than two seconds (about the same as the petrol engine). It turns out that the glow plugs are very useful!

What function do candles perform for a diesel car?

To ensure a normal temperature for starting the engine in the frost, additional heating in the combustion chamber is required. This function is performed by diesel glow plugs.
