What is Glow Plug


A glowplug is a heating device used to prop starting diesel machines. In cold weather, high speed diesel motors can be difficult to start because the mass of the cylinder block and cylinder head soak the heat of compression, preventing ignition due to the higher surface- to- volume rate. Pre-chambered engines make use of small electric heaters inside thepre-chambers — glow plugs — while the direct-injected engines have these glow plugs in the combustion chamber.
The glowplug is a pencil- shaped piece of device with a heating coil at the tip. This heating coil, when electrified, heats due to its electrical resistance and begins to emit light in the visible spectrum, hence the term "glow plug". The visual effect is very similar to that of a toaster oven.
The diesel injector spray pattern then impinges directly upon the hot tip of the glow plug during the injection of diesel at top dead center. This enables the diesel to burn even when the engine is insufficiently hot for normal operation. This reduces the cranking time needed to start the diesel motor.
