It takes two complete revolutions of the crankshaft and one revolution of the camshaft to complete the four cycles. On intake stroke with the intake valve open, we are drawing air and fuel into ...

With dual overhead cam engines, there are separate camshafts for exhaust valves and intake valves. These camshafts are made of hardened iron or steel and are connected to the crankshaft via timing ...

but also allows a builder to adjust the cam timing for performance. Next, the crank gear is installed on the 0-degree keyway using a brass punch to lightly tap it against the nose of the crank ...

It's the timing belt that connects the camshaft and crankshaft in the engine together ... One of these processes is the drawing of fuel from the tank into the cylinders. With the belt messed ...

Although the camshaft(s) and crankshaft work together to keep your motor firing and your wheels moving, they rely on more than just each other to accomplish these feats. Like many other automotive ...

"With an alternate-firing camshaft, you're basically taking energy and moving it rearward, away from the crank's snout, where it can be absorbed by the flexplate," Billy Godbold of Comp Cams says.
