Spark Plug Function

Video Transcript

"The function of the spark plug is to make the cylinder fire. So once you're in a combustion engine, once the power goes through, and goes through the distributor, and goes through a lot of the wires, it hits the spark plug, which then causes the spark to ignite the gas inside of the cylinder, whenever you reach that compression stroke. There are different kinds of spark plugs that you can get. There are just regular electro spark plugs that you can get, platinum spark plugs which it has like almost like, it has a platinum tip in this area where the electrode is in the spark plug. Then you have like cross fire spark plugs which they have different lobes on them right here, so you could have like, this is just a single tip right here, you can go from a single tip to anywhere up to four tips onto this area right here on the spark plug, so that kind of makes it to where it has a better range of fire, depending on what temperatures you're dealing with. When you get the high performance applications, the hotter the spark plug, the more fire that you get from the engine, so then you kind of want to watch out for that. Then, like I said in the other clip, you want to be careful not to drop this because if you crack the ceramic housing on here then basically the spark plug is no good. So basically that's what the function of your spark plug is, is to fire the engine."
