What Is the Idle Air Control Valve, & Why Is It Important for Maintaining a Healthy Engine?

You know that for proper operation, there are various inputs that the engine and the other parts need because all these things can not only make the car run but they help the car to run efficiently, smoothly, efficiently. Air is a necessary input just like the fuel. But the air should be present in a definite quantity to make the engine run properly. For their flow control, there are many components. An idle air control valve is such a type of component. If you own a car, then you have to know more about such a component. Here you will know about the idle control valve in detail and its importance.

What is an Idle air control valve?

The idle air control valve, also known as the IAC valve is a very important part of the air intake and the throttle system. Its main function is the regulation of air flow to the engine. It’s the rate of air flow which can make a change in the performance of the engine. The fuel used in the engine is burned to produce power and the fuel need air to burn, and the air should be in proper quantity depending on the amount of fuel. So, there is a fixed ratio found out, and this is maintained in the mixture of the air and the fuel in the cylinders. The air and the fuel in this ratio are a very important thing and maintaining it is carried out by various components in the engine and also the engine control module. The idle air control valve or IAC valve controls the air flow so that the engine would get a correct air quantity and can burn the fuel properly. More air can make the engine to run lean and less power will be produced. If the air quantity is less, then the engine would run rich, that is the fuel would not be properly burned due to such less amount of air.

It’s the engine control module which knows how much air is required to burn the certain amount of fuel, so it sends signals to control the idle air control valve in such a way that the quantity of air that the ECU wants is transferred to the engine.

The importance if the idle air control valve

The engine when burns down the fuel and air mixture, the power is produced to push the piston and make the crankshaft to turn. This turning and rotating of the crankshaft is the revving and the speed is measured in RPM (rotation per minute), this RPM is what makes the transmission and the drive train to run and make the wheels to rotate. The way of rotation of the crankshaft affects the performance of the engine. The RPM has to be maintained constant as much as possible. But some problems in the air or fuel intake system of other parts of the engine make the RPM to rise and fall constantly. This can lead to a rough running of the car as the drive train components would find it hard to make the car run smoothly as they get a fluctuating RPM. Hence the idle air control valve work to prevent the RPM of the car to go wrong.

Mostly the rough idling of the car makes more annoying thing. While the car idle, the engine maintains a proper RPM, the credit goes to the IAC valve which maintains a minimum idle speed for all low and high loads in the car by maintaining the air flow precisely. As the RPM is maintained and the car stops to shake during the idle. The engine health and the performance are improved. The rough idling can make the engine parts to wear quickly and lead to more loss of power. The ignition system and the other mechanical and electrical parts may not work properly and there are chances of having high deposits of carbon dust in the engine parts. If the air flow is not controlled, then the health of the engine would degrade.

Conclusion

The idle valves are one of the most essential parts in engine, so you have to take care of it.
