caption_attribution_description: English: This is a picture that I took of my glowplug out of my Peugeot 306 TDI being heated up by a 12 Volt Booster Pack. The glow plug is glowing white hot. I thought thaat it would be good on the glowplug page https://en.wikipedia.org/wiki/Glowplug
context_page_description: A glowplug is a heating device used to aid starting diesel engines. In cold weather, high speed diesel engines can be difficult to start because the mass of the cylinder block and cylinder head absorb the heat of compression, preventing ignition. Pre-chambered engines use small glowplugs inside the pre-chambers. Direct-injected engines have these glowplugs in the combustion chamber. The glowplug is a pencil-shaped piece of metal with a heating element at the tip. This heating element, when electrified, heats due to its electrical resistance and begins to emit light in the visible spectrum, hence the term glowplug. The visual effect is similar to the heating element in a toaster. The fuel injector spray pattern then impinges directly upon the hot tip of the glow plug during the injection of fuel at top dead center. This ignites the fuel even when the engine is insufficiently hot for normal operation, which reduces the cranking time to start the engine.
