how many degrees does a crank shaft rotate between power strokes?

Question

on a four stroke gas engine?

Answer 1

I think John paul's answer would be fine if it is a single cylinder

A common V8 would have 4 power strokes per rev - so maybe 360 divided by 4 = 90 degrees

I seem to recall the old Triumph 650cc motor cycles - where both cylinders fired at same time.... ponder it ..

Answer 2

on a standard v-8, it is 90 degrees of crank rotation per each cylinder firing. on a common 4 cyl engine, it is 180 degrees. on a 2 cyl, it is 360 degrees. on a 1 cyl engine, it is 720 degrees, or 2 revolutions of the crank. on a v-6 it is approx. 120 degrees. there are lots of diff. v6 engine designs, so that one will vary.

Answer 3

720 degrees two full rounds. Like this say it after me, Intake, Compression, -one turn- Power Exhaust -one turn- Intake, Compression, Power, Exhaust, Even in the Wankel Engine four stroke mean one down stroke intake one up stroke compression. one fast down stroke Power, and one up stroke exhaust. Stored energy in the flywheel keeps the three non powered strokes moving until "spark burn expand power push piston" Like a rifle shot!

Answer 4

360 degrees.
