No, glow plugs do not work when the engine is running. Glow plugs are part of the engine’s starting system and they heat up the air in the cylinder to help start diesel engines when temperatures are cold. The warmth from the plugs helps the diesel fuel to ignite easier and therefore helps the engine start more quickly.
When a diesel engine does not have a properly working glow plug, the engine can take longer to start and warm up, resulting in decreased engine performance and slower acceleration. Also, the glow plug is responsible for igniting the fuel in a diesel engine, and without a properly working glow plug, the fuel will not ignite at the right time
To correct you EVERY diesel is run off of compression ignition no matter what a glowplug simply warms the cylinder if its to cold out to help in compression ignition. bucket truck said: Cummins doesn't use glowplugs. They use an intake heater or grid heater. All 6 cyl. diesels big or small use this setup. Now V8's like Duramax and Powerstroke I've never heard of converting a diesel to cng. There isn't a place to put the spark plugs other than the glow plug hole and that wont work. You can modify a diesel to run with propane injected along with diesel tho. They can also run with a spray of windshield washer fluid (methanol/water) shot into the charged air pipe or intake manifold. Brett.
The glow plug does not ignite the fuel but is basically a small heater that helps with heating up the compressed air in the cylinder. Glow plugs, among other key advantages to diesel engines, are especially useful when starting a cold engine. How does a diesel engine work step-by-step? In order to understand the step-by-step process, let’s
How does a diesel engine start without glow plugs? Unlike gasoline engines, diesel engines do not use spark plugs to initiate combustion. Instead, they rely only on compression to elevate air temperature to the point where the diesel spontaneously combusts when exposed to hot, high-pressure air. Easy way to test your glow plugs. Check the glow plugs without removing them. If your plugs are good. Then its the module or harness. Yzk7.
