GENERAL INFORMATION

M2140000101567

For the cooling method, a forced water-cooling circu-
lation system is adopted and it has the following
characteristics:

• To reduce the coolant temperature variation, the

inlet control system which arranges the thermo-
stat at the inlet side of the coolant flowing from
the radiator to the engine is adopted.

• A down-flow radiator has been adopted in order

to reduce the number of parts and improve serv-
iceability.

• A ring fan has been adopted in order to reduce

noise.

• A radiator condenser tank is assembled into the

fan shroud in order to reduce the number of parts
and improve serviceability.

CONSTRUCTION DIAGRAM

In order to save weight, an air cleaner element with-
out plastics is used and the panel thicknesses of the
cover and the housing are optimised.

INLET MANIFOLD

M2150010000666

The inlet manifold is made of plastic for weight
reduction, and the surface roughness of the inner
walls of the ports has been improved to reduce
intake resistance.

EXHAUST SYSTEM

EXHAUST MANIFOLD

M2150006001105

The exhaust manifold incorporates a catalytic con-
verter. In order to reduce vibration, a spherical joint is
used at the front pipe connection.
