Feel the burn

Vehicle technology continues to evolve and ignition is constantly being tweaked to reap a cleaner and more efficient burn, this has resulted in the old school heating element being replaced with glow plugs capable of reaching temperature up to 1,000 deg C which have dramatically increased duty cycles.

Ignition expert Alan Povey of Denso warns that keeping up to date with the latest technology is vital for installers as, “Failure to carry out a complete check can ultimately lead to Glow Plug failure and, in some cases, an overloading of the regulating coil.  If this occurs the coil can fracture and debris can fall into the combustion chamber causing extensive damage to the engine. Put simply, we can no longer assume that by fitting new Glow Plugs all starting problems will be solved.  The system is much more complicated than this and it is vital that installers understand this.”

Denso’ glow plugs programme incorporates extended post-heating, ceramic and instant heating technologies and key benefits are said to include excellent cold starting and reliability. A total of 130 references provide 2,600 applications and 98% car parc coverage.
