understand and Q?

Hi , good day

I did not understand how to rotate Crankshaft 720 degrees ?. If the circuit 360 degrees

There are 720 degrees of rotation (two full revolutions of the crankshaft) in one engine cycle. The cams however rotate at half the crankshaft speed so they only rotate 360 degrees.

Does that answer your question?

Hi andre simon.

Ok thanks.

1:2 ratio

360 + 360 = 720

Turning Crankshaft 2 (360+360)= camshafts 1 (360)

Is this true ?
