combustion duration

Using the frame counter the entire combustion event is over at about 475/10000 seconds. That is a duration of .000475 seconds.

If we assume that the major portion of combustion runs from 30 deg BTDC to 90 deg ATDC that would be 1/3 of a crank rotation. 3 x .000475 equals roughly 1100 rpm so this would be similar to idle speed combustion.

found a math error corrected it equivalent rpm is more like a fast idle.
