Engine Mount Construction [Mzi-3.5] - Mazda CX-9 2007 Service Highlights

ENGINE MOUNT CONSTRUCTION [MZI-3.5]

• The surface of No.1 engine mount rubber is made of aluminum alloy. The torque rod structure regulates the
conventional rubber function and the rotation from the power train, and it has a vibration isolator.
• The No.3 engine mount rubber is oil-filled for noise reduction and vibration isolation.
• The No.3 engine joint bracket is integrated with the aluminum alloy engine front cover.
NO.1 ENGINE MOUNT
• The engine is supported at the following three points: front part of the engine (No.3 engine mount), one side of
the transaxle (No.1 engine mount), and the rear upper part of the transaxle (No.4 engine mount). The
supporting point at the side of the transaxle (No.1 engine mount) has been set at the transaxle's lowest edge.
With this layout, the No.1 engine mount absorbs the rotation force generated under the engine torque's
fluctuation and transmitted to the powertrain, and distributes the rotation force to the front and rear part of the
engine (pendulum).
