How do you calculate the number of sparks a plug will do in 100,000 miles in a 4-cyl engine. Assume that average speed over that mileage is 30 MPH at 2,500 RPM.
To go that distance at 30 MPH it takes: (100,000 x 60)/30 = 200,000 minutes
Total RPM: 200,000 x 2500 = 500,000,000 RPM
One spark per RPM so the total sparks is 500 millions.
Imagine that a plug does 500 millions sparks over its lifetime for less than $10-15 each.
Something likes park plug is so trivial nobody pay attention, but looking at the detail how it works is really open my mind.
