WebThe role of the camshaft is to open the intake and exhaust valves at the correct time. The camshaft has egg-shaped "lobes" that lift the valves open as the shaft rotates. The valves are spring-loaded, so when the cam lobes rotate off, the valves automatically close. … WebMay 1, 2008 · This means the number of crankshaft degrees the cam holds the valve open from the point that it raises 0.050-inch off the seat until it is lowered to within 0.050 from the seat.

Web4th stroke, the exhaust valve opens, the piston moves up. The engine has completed 2 revolutions and each valve has opened once. The camshaft travels at half the crankshaft speed because each valve opens only once on every two revolutions of the crankshaft. Therefore, In four-stroke engines, the camshaft gear has twice the number of teeth as on ...

WebJan 25, 2013 · In a 4-stroke engine, the crankshaft drives the camshaft at 1/2 crankshaft speed (obviously, since each valve opens and closes once for evvery two rotations of the crankshaft) . The camshaft typically … The crankshaft is one of the most significant components of your engine. Crankshafts turn linear power from the pistons into rotational power that the transmission can deliver to the wheels. It also uses all that … See more One of the most significant differences between the two is their shape. Camshafts are long and narrow, with offset lobes throughout.
