2 to 1 crankshaft turns 720 degrees crankshaft for 360 degrees cam shaft rotation. Thus a four cycle engine was born. Intake valve opens crank turns 180 valve closes crank pushes the piston up compresses this air fuel the intake valve let in 180 electricity causes a spark to jump the spark plug gap that ingnites the compressed air fuel mixture. Heat expansion causes the piston to shoot down another 180 and the exhaust valve opens. Here is where inertia helps that weight connected to the engine flywheel stores energy and keep the crank roating thru the exhaust cycle 180 exhaust valve closes and the next intake cycle begins over lap happes here. Thank You Gustaff Otto maker of the first four stroke engine. Makes me roar! 461 horsepower 456 lb TORQUE 6.0 LITER v-8

It has to be 1::2. Since you only want the valves to open everyother time that the piston comes to the top of the cylinder. One time it is the exhaust stroke and the next time it is the compression stroke and you don't want any valves open. The next time you get to look at the timing gears or pulleys count the number of teeth. The cam gear will have twice as many. good luck.

The camshaft runs at half the speed of the crankshaft.
That's a 1:2 ratio.

For every two revolutions or the crankshaft, the camshaft turns once.
2:1
