Glow Devices

Want to know more about the glow devices for ships and boats?

A marine diesel engine has electric glow plugs that help the engine of your ship or boat start when cold. A diesel engine uses self-ignition by compressing oxygen and fuel.

Just before the pressure is at its highest and the piston is at the top, fuel is injected by means of an atomiser and the ignition process begins.

Because the engine is still very cold after a standstill, it needs some help. Then the glow plug helps. A glow plug is located in the combustion chamber of the engine and is made of high-quality material.
