Engine mounts are critical components securing the engine and transmission assembly to the vehicle chassis. They isolate vibration and dampen noise generated by engine operation, preventing transfer to the passenger compartment. These mounts utilize varying durometer rubber or fluid-filled designs to manage dynamic loads and frequency. Construction typically includes a steel housing bonded to an elastomeric core, with variations for different engine weights and vehicle applications. Hydraulic or active engine mounts utilize fluid control to further minimize vibration under specific operating conditions. Failure manifests as increased NVH, driveline clunk, or engine movement.
