Glow plugs extend into the cylinder of the diesel engine and heat up to temperatures of up to +1000°C. This extreme heat is required to ensure the cold start of a diesel engine even in winter, with icy temperatures of up to -40°C. To prevent defects and wear, the MEYLE-ORIGINAL glow plugs are produced in accordance with OEM specifications – which includes the use of heat-resistant metal and twin heating coil technology. As a result, MEYLE-ORIGINAL glow plugs have optimum thermal transfer and high insulation capacity against leakage currents or flashovers. In addition, the inside of the glow plug is anti-hygroscopic on account of a special rubber seal – meaning it does not absorb any moisture which in turn prevents corrosion inside the plug. Use of top quality materials and optimally tuned components ensure the specified afterglow temperature of MEYLE-ORIGINAL glow plugs can be precisely maintained. This reduces exhaust emissions considerably, and is good for the environment.
Glow plugs should be replaced every 80,000 to 100,000 kilometres to prevent malfunction due to wear. Worn glow plugs may cause serious starting problems especially during cold temperatures in the autumn and winter months, and lead to the engine not running smoothly, causing an increase in pollutant emissions and smoke development.
There are many reasons why a glow plug does not function properly: in addition to ageing-related wear, incorrect installation, a defective control unit or inadequate processing of glow plugs may be reasons for defects. This can result in deformed, broken or burst glow plugs which may give rise to expensive consequential damages. For example, it may not be possible to remove the glow plugs or – in the worst case – parts of the glow plug may enter the cylinder and cause damage to it.
