I understand how a CPC V8 works. Fire a cylinder for every 90 degrees of crank rotation. 90 degrees x 8 cylinders = 720 degrees. How does the voodoo work?
No, just one at a time. I thought the word "alternately" would convey the "the right side then the left side then the right side and then the left side then the..." concept. Apparently not...Firing 2 cylinders at once?
I appreciate your feed back. Maybe it’s because of to many shot to the head over the years but I’m still not grasping the math. 720 degrees of crank rotation. 8 cylinders. 180 degree crank. Enlighten me. What am I missing?No, just one at a time. I thought the word "alternately" would convey the "the right side then the left side then the right side and then the left side then the..." concept. Apparently not...
In a four-stroke V8 engine, all cylinders fire once every two revolutions regardless of whether it's CPC or FPC. On each revolution of the engine, four cylinders are firing and the four that aren't are pushing out exhaust and sucking in clean air and fuel, getting ready to fire on the next revolution.
The Ford Coyote CPC firing order is 1-5-4-8-6-3-7-2 which is L-R-L-R-R-L-R-L. Cylinders 1, 5, 4 and 8 fire on the first revolution, and 6, 3, 7 and 2 on the second revolution.
Once every revolution in the CPC engine, one bank of cylinders fires twice in a row. On the first revolution, cylinder 1 immediately follows 2 and on the second revolution cylinder 6 immediately follows 8.
The Voodoo FPC firing order is 1-5-4-8-3-7-2-6 which is L-R-L-R-L-R-L-R.
As you can see, it doesn't matter which bank fires, the next firing is always on the other bank.
Never mind me. I just watched a bunch of YouTube videos. It’s the mechanical design of the crank assembly that allows it to fire every 90 degrees of crank rotation. Thanks for the reply’s. Sorry I’m so dense.Your math tells me your firing 2 cylinders at once. That is my confusion
