#89707 - divide by two? Responding to: ???'s previous message |
Andy Neil said:
Actually, that's every 2nd or 4th stroke - there are two strokes (one up, one down) per cycle (revolution). My mistake.... Andy Neil said:
Note that some 4-stroke engines spark at the top of every stroke - sometimes called a "spare" spark. The result should be divided by two to obtain the correct rpm instead of the multiplication by two (for the 4-stroke)? Is it feasible to use the sparking interference to detect the rpm? |
