ENGINE LUBRICATION

The engine lubrication is of the wetsump method to draw
up the oil forced by the oil pump. The oil pump is of a
trochoid type, and mounted on crankshaft at crankshaft
pulley side (a). Oil is drawn up through oil pump pickup
tube (b) and passed through pump (c) to oil filter (d). The
filtered oil flows into two paths in engine block. In one
path (e), oil reaches crankshaft journal bearings. Oil
from crankshaft journal bearings is supplied to connect-
ing rod bearings by means of intersecting passages
drilled in crankshaft, and then injected from a small hole
provided on big end of connecting rod to lubricate piston
(f), rings, and cylinder wall. In another path (g), oil goes
up to cylinder head and lubricates rocker arm (i), valve
(j), camshaft (k), etc. through the oil hole provided on the
rocker arm shaft (h).

D102B002

CYLINDER HEAD AND VALVE TRAIN

The cylinder head is made of cast aluminum alloy for
better strength in hardness with lightweight, and cam-
shaft (k) and rocker arm shaft (h) arranged in-line sup-
port.

D102B003

The combustion chambers are formed into the manifold
combustion chambers with increased squish parts for
better combustion efficiency and its intake and exhaust
