A crankshaft has one (or more) offset sections where a connecting rod is attached around it. The connecting rod moves back-and-forth (or up-and-down) ONCE for every rotation of the crankshaft. The crank will always move in a circle, moving the connecting rod in a smooth sine wave like motion. The power can flow in either direction. That is, the crankshaft can drive the connecting rod, or the connecting rod can drive the crankshaft.
A camshaft has a cam follower that rides on the cam. The cam on the camshaft can have more than one lobe (high spot) on it, so it is possible for the cam follower to move back-and-forth (or up-and-down) more than once for each rotation of the camshaft. The cam can have a complex shape, so the cam follower can move in motion patterns that are non-sine wave like. Usually the power flows in only one way. The camshaft will drive the cam follower, but the cam follower usually cannot drive the cam.
If a significant amount of power needs to be transmitted, a crankshaft is usually used. If motion (with minimal power) needs to be transmitted, particularly if it is a non sinusoidal motion, then a camshaft is used.
In a typical piston engine (gasoline, diesel, etc) uses a crankshaft to convert the linear motion of the pistons into rotational motion. The crankshaft is good here because it must be able to push the pistons as well as the pistons pushing it. Also, a substantial amount of power must be transmitted.
In the same engine, a camshaft is used to operate the valves. The valves in the engine should stay fully closed most of the time, then open quickly, stay open for a bit, and then close quickly. The camshaft works well to produce this non-sinusoidal motion where little power needs to be transmitted.
the relationship between cad and cam is that one is called cad and the other is called cam ...... can't u see they both end differently
CAD stands for Computer Aided Drafting and is used to create working blueprints and designs. CAM is Computer Aided Manufacturing, where computers and software control machinery that makes things.
many cam
What is cad cam
A Four-lobed cam is like a snail cam but i has four quick drops instead of just one big drop.
Cam spins at half the speed of the engine.
A cam sensor tells the computer when number one compression stroke is happening, the crank sensor tell the computer when to fire the sparkplugs.
cam and crank shaft
One thing is for sure, it wouldn't run.
it could be one of the sensors crank shaft or cam shaft
crank or cam shaft position sensor is sometime the issue.it will not fuel if it cannot find the position of the cam or crank
Crank shaft sensor need replaced or cam shaft sensor
1. Pistons 2.Cam shaft 3. Crank shaft 4. Engine walls
ck cam shaft sensor, check crank shaft sensor also.
cam chains are a chain the attach to the crankshaft and the cam shaft , the crankshaft is the shaft making the pistons go up and down the cam shaft makes the valves open and close, the crank shaft and cam shaft have to be aligned a certain way or the car will not fire, this is called "timing" . if your looking for where it is , its most likely in the front of the engine get a pro to look at it.
A bad cam or crank sensor can cause a no start, but the engine will still crank or turn over.
I would like to know where the cam sensor is on a 1999 pathfinder and is there one or they calling it a crank shaft sensor The cam shaft position sensor is located in the distributor.
