Aside, I had never heard of a glow plug, after working on a few generations of cars... I figured it might be a US vs rest of the world thing with naming something like a "spark plug".
But I looked it up and for the benefit of anyone else who's never worked on diesel, it's part of the diesel ignition cycle it seems. TIL!
- doubled112 1y agoA glow plug is basically a heater. Diesel being injected into the engine isn't ignited by a spark, but spontaneously by compression. This can't happen if the temperature in the cylinder is too low. Having your fuel being ignited by the engine running, as opposed to something like a spark plug, has interesting side effects like dieseling and runaway.
