Glow Plugs

A serious disadvantage soon appeared following the introduction of diesel engines in vehicules. Diesel engines require high combustion temperatures
(approximately 750°C) to start. The effects of compression make starting impossible under adverse conditions caused by low temperatures. The cold engine in combination with the cold air it makes start-up possible only with the addition of heat.

Glow Plug provide the additional heat necessary for easy engine starting, with the time requiered for this to occur being reduced day to day. This is possible thanks to new materials and advanced technology in this area. As a rule, pre-heating time today is between 3-7 seconds and is usually timed by an electronic control panel which uses a thermal sensor or probe installed in the engine to measure engine temperature and adjust the heating time needed for flawless starting.
