Controllable Engine Mounts: Notes
The 4-cylinder engines are fitted with controllable engine mounts. The controllable engine mounts achieve the following:
- They insulate the car body from vibrations as well as possible when the vehicle is at a standstill and idling
- They prevent 'bouncing' when the vehicle is being driven on poor road surfaces
('bouncing' = 'dancing' of the engine mass on the engine mounts)
Deployment of the controllable engine mounts:
- E60: N46B20O2 (Rest of World = RoW) and N43B20O0
- E8x, E9x: N43B16O0, N43B20U0 and N43B20O0
NOTE:
The N43 has been developed for the European market.
The N43 with direct fuel injection will only be available in ACEA (ACEA: Association of European Automobile Manufacturers).
