What is Camshaft adjusters

The camshaft is a rotating object— usually made of metal— that contains pointed cams, which converts rotational motion to reciprocal motion. Camshafts are used in internal combustion engines (to operate the intake and exhaust valves), mechanically controlled ignition systems and early electric motor speed controllers. Camshafts in automobiles are made from steel or cast iron, and are a key factor in determining the RPM range of an engine's power band.

How Does a Camshaft Work?

As the camshaft rotates, the lobes of the cam move up and down. Every rotation causes a single cam lobe in DOHC engines to push down the valve and open it to the cylinder. Similarly, in the SOHC and pushrod engines, the cam lobe pushes the rocker arms (or pushrods, then the rocker arms) to open the valve. As the cam's lobe further rotates, the valvespring forces the valve back up and closes it.

The camshaft is usually connected to the crankshaft utilizing a timing chain or timing belt. Timing gears may also be used in some push-wheel engines. The camshaft gear has twice as many teeth as the crankshaft gear, allowing it to rotate at half the crankshaft's speed. There are four distinct strokes in the camshaft: intake, compression, power, and exhaust.

Timing

Timing is essential. Valves must be opened and closed at specific intervals concerning the position of the cylinder. For example, as cylinder #1 arrives at the top dead center (TDC) on the exhaust stroke, the camshaft opens the intake valves and closes the exhaust valves. Simultaneously, the #3 cylinder could reach the TDC at the compression stroke so that the camshaft would leave the valves closed.

Camshafts fitted with variable valve timing (VVT) use hydraulic actuators to advance or delay the valve's timing about the crankshaft angle. VVT enables high-speed or low-speed performance.

Using specialized variable valve lift (VVL) camshafts and computer-controlled solenoids or hydraulic actuators, ECM can choose between two valve lift options depending on the driver's requirements.

For vehicles with direct fuel injection, diesel engines, and most gasoline direct injection engines, the high-pressure fuel pump (HPFP) is driven by a lobe on one of the camshafts.
