HOW DO GLOW PLUGS WORK?

No matter how you look at it, car technology has come on leaps and bounds over the past decades. And, while some of these advances are immediately noticeable and appreciated, such as electric windows and smoother suspension systems, others, like glow plugs, are hidden under the bonnet and forgotten about unless something goes wrong. This shouldn’t be the case. Heat glow plug technology has significantly improved, with BERU, for example, dramatically improving the time it takes to start your diesel car – especially on cold mornings.

So, let’s appreciate the hidden and take a look at BERU glow plugs – what are they, the different types available and how they compare to the competition.

What is a glow plug?

To get started, we need to go back to basics: what is a glow plug? And, what does a glow plug do?

A glow plug is a heating element that heats incoming fuel and air to encourage efficient fuel combustion in a diesel engine. The fuel combustion starts your engine so that you can drive. Each cylinder of your engine has one glow plug, either in the pre-chamber (pre-chambered engines) or in the combustion chamber (direct-injection engines).

GLOW PLUG SYSTEMS

The starting process of an engine heavily influences the exhaust gas values of a vehicle. Together, glow plugs and their connected components (glow plug control modules, glow plug relays and glow plug combustion sensors) play an important role in reducing emissions helping to protect the environment.
