FAI is proud to be the Lucas Diesel sole agent for Europe. Lucas Diesel glow plugs are made in Europe in one of the most technically advanced factories. All glow plugs are 100% factory tested to ensure best performance. The range covers over 4000 applications for European and Asian vehicles.
Diesel engines have spontaneous ignition, which means the injected fuel does not require a spark to ignite. The high temperature which occurs as a result of compressing intake air is sufficient to ignite the fuel. However, in cold conditions more energy is required to help ignition so good glow plugs are a key factor for every cold start.
Glow plugs compensate for the heat loss caused by the cool components and cold air and ensure that temperatures are optimal before ignition. The plug is energised before the engine is started, the heater tube rises rapidly to over 800 degrees C for quick ignition. Diesel engines that fail to start easily are not only frustrating, they discharge un-burnt fuel, Lucas pre heat technology ensures fast starting and so minimises this problem. Post glow takes place after the engine is running, it prevents heat loss whilst the engine is warming up, typically 3 minutes. This reduces toxic emissions and white and blue smoke from the exhaust ensuring the engine runs smoothly, with no cold start knocking.
Glow plugs are often ignored until starting problems on a cold morning. The rise in the diesel parc means that glow plugs should be considered a service item. Unlike spark plugs, glow plugs give little warning before failure and often is undetected until it’s too late!
