Fouling deposits
WebJun 23, 2024 · Fouling deposits from oil, antifreeze or excess fuel can coat the spark plug. To the extent that these deposits offer an alternate path for the high voltage, they can cause misfires. This didn’t happen in the experiment vehicle, leading to its extremely long plug life. There are other failures as well. WebFouling definition, an encrusted deposit, especially on a submerged object, as the hull of a ship. See more.
