Depends on the type of engine. Some use chains and others use belts. Chains can be noisy and belts can brake. The Suzuki Ignis uses a special Suzuki 'silent chain'.
A camshaft opens/closes the intake/exhaust valves at predetermined points of the piston travel. The cam is driven by the crankshaft, the rotating cam lobes operates thru lifters/followers that ride against the lobes.
An automotive engine's camshaft rotates at A. the same speed as the crankshaft. B. one-quarter the speed of the crankshaft. C. one-half the speed of the crankshaft. D. twice the speed of the crankshaft.
it's a 2 to 1 ratio For ALL 4 cycle engines, no matter how many cylinders, the crankshaft turns twice for every turn of the camshaft.
Many reasons. Extreme valve spring pressure, sometimes if gear driven, the crankshaft will transmit vibration, thus breaking it, or maybe a connecting rod let go, and hit it. Or, it could have been a weak casting, though that is uncommon. These are the only reasons I have seen, in the field.
SHOULD BE THE BELT DRIVEN ACCESSORY DIRECTLY ABOVE THE CRANKSHAFT (LOWEST BELT DRIVEN ACCESSORY ON ENGINE)
By a chain or belt from the crankshaft.
The camshaft is driven by the crankshaft, via chain, usually, or, gears.
The camshaft typically turns at half the speed of the crankshaft in a four-stroke engine. This is because the camshaft is driven by the crankshaft and needs to rotate once for every two rotations of the crankshaft to synchronize the opening and closing of the engine's valves. This ratio ensures that the intake and exhaust valves operate at the correct times during the engine's cycle.
The connecting rods and pistons are connected to the crankshaft. Ignition of the air/fuel mixture in the combustion chamber pushes the pistons down which rotates the crankshaft which generates the engines torque/power. The camshaft controls the opening and closing of the valves which allows the air/fuel mixture to flow in and out of the engine. The camshaft is driven by the crankshaft and is kept in proper sequence by a timing belt/chain or gears.
The crankshaft is turned by the pistons going up and down. The cam shaft is driven by the timing belt or chain that is turned by the crank shaft. The camshaft on a four cycle engine turns 2 to 1 crankshaft revolution. The cams on the camshaft operate the intake and exhaust valves. intake valve on one revolution and exhaust on the next.
It is the gear that drives the camshaft. It is affixed to the end of the camshaft. It is driven by a belt or chain that goes around another gear at the crankshaft and has one or more tensioners to keep it tight.
In a twin-cylinder four-stroke engine, the crankshaft completes one full rotation for every two strokes of the pistons. Since the crankshaft is turning at 1000 RPM, the camshaft, which is typically driven by the crankshaft at half that speed, will turn at 500 RPM. Thus, the camshaft in this engine will be rotating at 500 RPM.
A camshaft is driven by a linkage from the crankshaft, and operates your valves; directly in an OHC setup, and via pushrods otherwise. Cam "follower" is just an updated "roller bearing" for a camshaft.
It has a belt and a chain. Belt driven from fuel pump to camshaft, and chain from crankshaft to fuel pump
The tone wheels on the camshaft and crankshaft are different.The tone wheels on the camshaft and crankshaft are different.
check for the camshaft/crankshaft sensors... where is your camshaft/crankshaft sensors
Camshafts can be driven by a timing belt, timing chain, or gear mechanism. These mechanisms transfer power from the engine's crankshaft to the camshaft to control the opening and closing of the engine's valves.
