9000 Hatchback L4-2290cc 2.3L DOHC Turbo EFI (1994)
DESCRIPTION
The hydraulic mounting has two chambers containing a special hydraulic fluid. Interposed between the two chambers are a diaphragm and a
passage, the length and diameter of which determine the damping characteristics of the mounting. The forces generated by normal small
movements of the engine are absorbed by the diaphragm.
OPERATION
If the engine movement is more pronounced, the damping action of the diaphragm is insufficient, and fluid is forced from the upper into the lower
chamber, equalizing the pressure. Thus, the damping action of the mounting is progressive, the damping force increasing as the load on the damper
increases.
ADVANTAGES
Hydraulic mountings have the following advantages:
^
Improved damping of horizontal engine movements during acceleration
^
Improved damping of vertical engine movement on bumpy roads
^
Improved damping of engine movement when idling
^
Reduction in structure-borne sound between engine and body
