The camshaft is driven by the crankshaft, via chain, usually, or, gears.
The camshaft turns one revolution to the crankshafts two revolutions.
The camshaft turns one revolution to the crankshafts two revolutions.
The engine's camshaft rotates at half the speed of the crankshaft. The crankshaft turns two full turns for every one full turn of the camshaft.
the camshaft turns once to every time the crankshaft turns twice meaning it is 2:1
A camshaft would travel 180 deg for every 360 that the crank turns.
a camshaft moves the rods up and down as to open and close the valves. a rod rides on the camshaft and the lobes are oval, so every time it turns the rods are pushed up and when the lobe is down they are closed. this happens very fast, the rod rides on camshaft and pushes on rocker arms to open and close valves.
The oil pump drive gear, which is driven by the camshaft, drives the distributor.The oil pump drive gear, which is driven by the camshaft, drives the distributor.
the shaft that runs through the distributor. it turns on the camshaft housing to make the top of it spin which makes the points open and close, and turns the rotor to send spark to the plugs
The camshaft turns at half the speed of the crankshaft. If you count the gears, you should find that there are twice as many on the camshaft. If you line up the marks at TDC, then turn the crankshaft 360 Degrees, you should find that the camshaft has turned 180 degrees. So, every time the crankshaft turns back around to TDC, the camshaft will turn 180 degrees and if that's what your're seeing, then everything is normal.
The camshaft turns one half turn for every full turn of the crankshaft.
Check Timing First Sounds Like That Is Your Problem. If it turns out to not be the ignition timing, it could also be the camshaft timing. If your camshaft is mistimed it means that your timing chain or timing belt has slipped and must be replaced.
In a four-stroke overhead-cam engine, the timing chain connects the crankshaft to the camshaft. The camshaft opens and closes the valves in the cylinders and turns at half the speed of the crankshaft. Many engines now have a cog-belt instead of a chain.
