: Turbo6LUOO43The lubrication system is the pressure-feed, full-
flow filter system. The engine oil sent under
pressure by the gear-type oil pump is filteredthrough the cartridge-type oil filter before being
delivered to the various engine parts.

. *the mounts, the principal axis of inertia support
system is employed.
This principal axis of inertia support system of
mounting functions to support the upper
part of the
engine and the upper part of the transaxle, thereby
effectively suppressing engine vibrations. Note that
there are the following features at the various
installation parts.
lThe transmission of engine vibration to the body
is reduced by the installation, via bushings, of
the centermember to the body.
lThe insulators each have a cavity that serves to
effectively absorb vibrations.

CavityPRINCIPAL AXIS INERTIA SUPPORT SYSTEM
The vibrations generated from the engine and drive train
consist of such eiements as vertical vibrations caused by the
engine’s combustion processes, as well as
rollings caused by
the torque reaction force of the tyres and the crankshaft
rotation etc.
In order to effectively suppress these vibrations, the principal
axis of inertia support system, by which the components that
contact the principal axis of inertia are mounted, is employed.
INSULATORS
Absorption of Minute Vibrations
The minute vibrations that are generated during idling and
during driving are absorbed because the spring constant is low
as a result of the fact that insulator A only causes vibration of
the space within the cavity.
Absorption of Larger Vibrations
The larger vibrations that are generated during starting from a
_stop and during acceleration are absorbed because insulator A
and insulator
B contact, and the spring constant becomes high.

using rubber hangers and, in addition, a flexible pipe
is used at the front exhaust pipe in order to reducethe transmission of vibrations from the exhaust
system to the body.
