The idle air control valve, commonly referred to as the "idle speed control valve," manages how quickly your engine idles. The computer in the engine is in charge of this. Your car may occasionally stall or idle abnormally due to faulty parts.
ISC (Idle speed control) atau disebut juga IAC (Idle air control) merupakan suatu rangkaian elektronika yang digunakan untuk mengatur banyak sedikitnya udara yang melewati idle port ketika katup gas dalam posisi tertup atau tidak diinjak pedal gas. PDF | This paper proposes a novel modelling and optimization approach for steady state and transient performance tune-up of an engine at idle speed. In | Find, read and cite all the research 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. The idle speed control mode is used to prevent engine stall during idle. The goal is to allow the engine to idle at as low an RPM as possible yet keep the engine from running rough and stalling when power-consuming accessories, such as air-conditioning compressors and alternators, turn on. Idle speed control is mainly control the volume of idle speed air intake, which is to adjust the opening degree of the idle speed inlet valve to implement the actual speed approach target aoLO.
