ACM, the full English name is Auxiliary-Control-Module, Chinese explanation: auxiliary control module. The ACM (Active Control Mount) system needs to be connected to the engine's intake manifold through an electromagnetic control valve (ECM) and is controlled by the electromagnetic control valve. The following extended information: Function of ACM: Under different conditions, the ACM (Active Control Mount) system provides corresponding forces to counteract the engine's impact inertia, effectively absorbing engine vibrations and the engine vibrations during idle start-stop function operation, achieving more stable driving control and ride comfort.
I remember friends often asking me what this car ACM thing is while driving. Simply put, ACM in the automotive world refers to the Air Conditioning Control Module, which acts like a tiny brain in the car specifically managing the air conditioning system. It automatically adjusts fan speed, cooling intensity, etc., based on the set temperature to ensure a consistently comfortable cabin environment—especially helpful during long summer drives to avoid unbearable heat. This device is similar to a home air conditioner's controller but more compact and intelligent, integrating sensors to monitor real-time temperature changes inside and outside the cabin. Without it, manually adjusting the AC would require frequent operations, which is both distracting and unsafe. Additionally, modern car ACMs are connected to the vehicle's computer, coordinating other functions like ventilation and humidity control to enhance the overall driving experience.
