The lobes are positioned along the axle such that rotation of the axle causeseach lobe to open and closeits valve which allows the intake valves to be lifted to allow fuelair into the cylinder and lowered to seal off the cylinder when the. The camshaft controls the opens and closes the valves at the correct times for the engine to actually run. The cam phaser is a part of the variable valve timing system.

It determines how much when and how long. Your cars cam belt is a vital piece of the engine. The cams are oval-shaped bulges placed precisely along the shaft.

In some engines it is placed on the cylinder head. As the camshaft spins the lobes open and close the intake and exhaust valves in time with the motion of the piston. Ad Search from over 10 Million Auto Parts.

Camshafts are manufactured of hardened steel or cast iron alloy. Cam is shorthand for camshaft the engine part that opens and closes the valves to let the air-fuel mixture in and out of the combustion chambers. The engines camshaft controls the valves letting fuel and air in and out.

The camshaft is a rotating object usually made of metal that contains pointed cams which converts rotational motion to reciprocal motion. A camshaft is only a shaft on which cams are installed. Quite literally the camshaft is a shaft with cams attached to it.

The cam belt is made of of sturdy composites like Kevlar and polyurethane with teeth on it thats designed to keep the camshaft and crankshaft in time. As the shaft turns cams along. The camshaft is mounted on bearing in the lower part of the cylinder block most in-line engines.

Camming a car refers to increasing the duration and timing of the valve openings. Or in automotive terms increasing the lift and timing. A cam shaft in a car is basically an axle that has a lobeassigned toeach valve.

The valves and camshaft together make up the valve gear or valvetrain. On single and double overhead cam engines the cams are driven by the crankshaft via either a belt or chain called the timing belt or timing chain.

Camshafts are used in internal combustion engines to operate the intake and exhaust valves 1 2 mechanically controlled ignition systems and early electric motor speed controllers. The result of all the camshaft specifications is where in the RPM band the motor will make the best power. These belts and chains need to be replaced or adjusted at regular intervals.

What is a cam in a car engine. The camshaft is a rotating shaft or shafts in an engine that activates the intake and exhaust valves for each cylinder. Lift or valve lift refers to how far the cam opens the valves.

It turns out that there is a direct relationship between the shape of the cam lobes and the way the engine performs in different speed ranges. If we focus this term camshaft to the modern day automobiles it refers to a vital part usually located under the engine. Clarification needed A common example is the camshaft of an automobile which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
