Engine Mount: Description and Operation

System Description

Overview
The active control engine mount (ACM) system reduces the amount of engine vibration that creates engine noise which is transmitted to the passenger's compartment.

The ACM system consists of the ACM actuators, the engine mount control unit and the powertrain control module (PCM).

The PCM sends the crankshaft position (CKP) sensor information and camshaft position (CMP) sensor information to the ACM. The ACM uses this information to predict the amount of vibration created by the engine.

The ACM system then uses the ACM actuators to generate a canceling vibration that operates like the active noise control (ANC) and reduces the amount of noise and vibration in the passenger's compartment.
