Glow plugs can be found in diesel engines and are assembled at the factory. Glow plugs are important automotive parts that ensure that the diesel engine starts when there are freezing temperatures outside, for example. Glow plugs also ensure a low-emission and low-noise warm-up phase of the diesel engine.
Glow plugs - how do they work?
Glow plugs ensure that the diesel fuel is burned more quietly and completely during the warm-up phase than would be the case without glow plugs. The important automotive parts are necessary in the context of environmental protection for diesel engines and are developed in cooperation with the automotive industry. Glow plugs ensure a diesel quick start that is more environmentally friendly than without glow plugs and, depending on the plug variant, starts safely up to a temperature of -30 ° C. As a result, the engine runs more smoothly and soot emissions are up to 40 percent lower with glow plugs. If there are no glow plugs installed in a diesel engine, this can be recognized, for example, by the blue or white smoke that is increasingly emitted from the exhaust during the engine's warm-up phase. The noticeable smoke is the result of a too low ignition temperature. The turbidity of the smoke gases, i.e. what is emitted as white or blue smoke from the exhaust, can be reduced by up to 40 percent if glow plugs are installed appropriately.
Glow plugs - are there any sophisticated technologies?
Glow plugs are commercially available in improved, more powerful versions. For example, variants for diesel engines are manufactured that use a Formula 1 technology including a leakage current barrier. Even if a Formula 1 vehicle is of course NOT operated with a diesel engine. Nevertheless, the technology comes from racing. A so-called interference suppression provides improved cooling and a stable voltage on the glow plugs. At the same time, the resistance ensures optimal idle quietness. A longer glow plug service life is ensured by means of center electrodes, which have a copper core and are thin-walled. Improved glow plugs are usually equipped with a longer insulator tip. Due to the longer insulator tip and a wider seat diameter, cooling can be done better. Furthermore, the temperature range of the glow plug is expanded. The modified glow plugs also cause less soot, which increases the service life.
Modified glow plugs - what to look for when buying?
Improved glow plugs for the diesel engine have a large electrode gap and can thus produce optimal performance. When buying, you should pay attention to high-quality materials, such as titanium alloys. Furthermore, the glow plugs should be suitable for high sub-zero temperatures and ensure optimal fuel combustion and reduced emissions. The articles should also be erosion-resistant and have a long lifespan. It is also important that the glow plugs, as an electronic component, are insensitive to external influences. Other systems of the car must not be influenced. It is advisable to consult a specialist when installing modified glow plugs. Tuning workshops can help you find the right products and offer installation by qualified personnel. Customer reviews are also interesting to find and install improved, modified glow plugs for the diesel engine.
