Frozen with Fear: Glow Plugs and Cold Starts

There’s no greater horror than a generator that won’t start. Whether it be due to cold or inactivity, sometimes even the best Diesel generators just don’t start. To avoid the nightmarish horror of an inactive generator this Halloween, you need a glow plug. Read on to learn about a strange glowing object you can depend upon when you’re frozen with fear.

What is a Glow Plug?

A glow plug is a small piece of metal, with a heating element at the end. It is designed to start a Diesel engine. Unlike a petrol engine, a spark plug is not built into a Diesel generator. This is because compression is used to generate hot pressurised air to create combustion in a Diesel generator. Therefore, a glow plug is required to create the ideal temperature for the air in the engine to cause combustion.

How Does a Glow Plug Work?

When a Diesel generator is turned on in particularly cold weather, it won’t start right away. First, the glow plug will begin to heat the air inside the generator. On older models, this can take up to 6-8 seconds, but your typical modern glow plug will heat in around 2-3 seconds. Many glow plugs heat up to over 1000 degrees, giving them their distinctive glow. Once they have heated the engine to an ideal temperature for combustion, a glow plug may stay heated to ensure that temperature can be maintained. This could last anywhere from a few seconds to a few minutes depending on the temperature
