You might want to put a little more thought into that concept.

Either that, or remember the old saying: "When you find yourself in a hole, stop digging."

You still haven't grasped the relationship between a drive gear and a driven gear.

At TDC the crank is at 0 degrees. Where the timing mark is on the cam is irrelevant. You can put the cam at any position you want but the crank would still be at TDC. The #1 crank journal would be at its highest point.

Whether it is on its compression stroke or exhaust is dependent on where the cam gear is positioned. Moving the cam gear changes VALVE opening and closing.

The crank doesn't care. All it does is move the pistons up and down.

You are just arguing for the sake of an argument.

You are the one inventing arguments to distract from your basic failure to understand fifth grade arithmetic. My only argument has been that 1:2 does not equate to 18:9 like you claimed it did. Everything else was in response to the irrelevant facts you presented in a failed attempt to explain something that you didn't understand in the first place.

If one gear rotates twice as fast as the other, it doesn't matter which gear is driving. The big gear still goes slow and the little gear still goes fast. Let us know when you have grasped that concept.

And that is supposed to explain how 18º rotation at the cam equals 9º at the crankshaft?

And, for over half a century, I had believed that the pistons rotated the crank shaft. Thanks for setting me straight on how things really work. Evidently, I have difficulty understanding mechanical relationships.
