Mechanical 17 illustrations ~410 words

GENERAL DESCRIPTION

Inertia principal axes system is incorporated into the engine mount system.

  1. Longitudinal Installation type of cylindrical liquid-filled engine front mounting bracket is used for reduction of the idle vibration improvement of ride feeling.
  2. For transaxle mounting body side bracket, liquid-filled mount is used to improve ride feeling by optimizing insulator.
  3. Upper installation of roll stopper bracket reduces engine rolling, and increase of insulator bore also reduce idle vibration.
