What Is Cam Phaser and Why It Matters for Your Car?

There are various components which improve the performance of the car and help in consumption of very less fuel as possible. These components are available of both electrical and mechanical. Hence, they are given more priority and the car specialists always advice to fix the problems with these components as early as possible. Some are older and some are installed now a days in modern cars. Before the timing was considered to be fixed and cannot be modified but the use of cam phaser brought a changed in this system. Cam phaser is one of the mechanical components that improves the performance and the fuel economy. Here you will know about the cam phaser in detail and its importance in today’s cars.

Cam phasers and its uses

The cam phaser is a component of the engine which can adjust the cam shaft position. You all know that the camshaft and the crankshafts are synchronized by the help of the timing belt or chain. There is a VVT or variable valve timing system which works to change the valve timing by adjusting the camshaft and to do this it uses it most important part which is can phaser also known as can actuators. As its name itself tells that it changes the phase or the position of the cam shaft as per the requirement to improve the engine performance.

Then how can the performance would be improved by the adjusting the phase of the camshaft? The camshaft positioning in the right time highly improves the performance to high extent. It is the camshaft which controls the opening and closing of the intake and exhaust valves, by doing this, it controls the amount of fuel and air entering to the combustion chamber and the amount of exhaust gasses released out of the combustion chamber. The fuel and the air amount are what that makes the generation of more or less generation of power. Hence the cam phaser just adjusts the timing in such a way that the engine can run more with a less intake of fuel. This is how the cam phaser provides the variable or adjustable timing to the cam shaft to control the valves movement and improve the performance.

It is the engine control unit or the car computer which controls the cam phaser. When there is correct time, the cam phasers get the signals to make the adjustment of the camshaft timing. The VVT system consists of a solenoid which gives pressure to the cam phaser so that it would be activated and to make the solenoid work, the VVT gets the signals from the PCM.

Importance of cam phaser and how dangerous to use faulty

The cam phaser acts in correct times to adjust the timing and bring a change in the performance. In older cars there were no cam phasers so the fuel efficiency was not that much good as the fuel is not conserved. The cam phaser conserves the power and provides the best performance it can. The cam phaser is controlled by PCM to make a change in the control valve.

The valves at the cylinders open and close to control the fuel and the air amount in engine. When the valves close, flow of the air and fuel is stopped, when the valves open, then fuel and air flow into the chambers. Similarly, the opening and the closing of the exhaust valve can affect the intake. To have more power, the camshaft timing becomes slow and the slow timing can make the valves to remain open for long and allow more fuel and air into the chamber. When the timing is faster, the opening time of the intake valves is very less that’s why less fuel and air enters into the combustion chamber for one stroke and leads to less power. You cannot get such type of control if there is faulty or no cam phaser, a cam phaser is useful but can become faulty leading to some major engine performance issues, which should be avoided.

Conclusion

Get your cam phaser fixed as soon as possible so that you would not get any issues in the engine, take the help of authorized service centers to get good service.
