An idle air control actuator or idle air control valve ( IAC actuator / valve) is a device commonly used in fuel-injected vehicles to control the engine's idling rotational speed ( RPM ). [1] In carburetted vehicles a similar device known as an idle speed control actuator is used. Description This chapter discusses engine idle-speed control. The engine speed at idle is maintained at a desired value despite changes in engine loads (e.g., due to accessories such as an air-conditioning compressor). The controlled variable is engine idle speed and it is measured as discussed previously. Idle speed control adalah bagian dari sistem Electronic Fuel Injection yang fungsinya mengatur putaran mesin, kenali lebih lanjut di sini. The idle speed controller ensures that the idle speed of the engine remains constant in all load conditions. On this page you can find out about how the idle speed actuator regulates the intake air mass of the engine, and how the failure of this actuator impacts on the engine running. Practical tips for troubleshooting and assembly instructions The idle air control valve controls the air needed to maintain a steady idle speed. It essentially acts as a bypass of the throttle body plate. The solenoid in an idle air control valve can get It is however an aspect that is often overlooked or incorrectly tuned, leading to unstable idle and stalling. In this webinar we'll discuss what you need to know to get a rock solid idle, what hardware is required, and how to approach the tuning on the ECU Master EMU Black. 00:00. .
