1) Stalled Engine - A bad idle speed control valve will cause your engine to stall. Depending on the extent of the wear 2) Idle Speed Changes - When you bring your vehicle to a complete stop, you may notice your engine idle speed changing 3) Difficulty Steering - During a situation where
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.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
Fluctuating Idle Speed Your vehicle's idle control valve is supposed to keep everything smooth when idling, so it makes sense that if it's acting up, your idle speed is going to fluctuate. While it depends on what's wrong with the valve, a fluctuating idle speed is one of the most common symptoms.
The main objective of the idle speed control is to maintain the idling speed at 650rpm and to reject as quickly as possible the extra load exerted on the engine system during idling mode. Comparing the three methods, it shows that PID tuning by ILA produced better results than heuristic tuning and pole placement.
Idle speed control adalah bagian dari sistem Electronic Fuel Injection yang fungsinya mengatur putaran mesin, kenali lebih lanjut di sini.
