GENERAL DESCRIPTION

Engine

The engine is a water-cooled, in-line 3 cylinders,

4-stroke cycle gasoline unit with its S.O.H.C. (single

overhead camshaft) valve mechanism arranged for

“V”-type valve configuration.

The single overhead camshaft (S.O.H.C.) is mounted

over the cylinder head; it is driven from crankshaft

through timing belt. Unlike conventional overhead

valve (O.H.V.) engines, this engine has no pushrods.

Thus, drive for valve is more direct and enables the

valves to follow the crankshaft without any delay.

Engine Lubrication

The oil pump is of a internal gear type, and mounted on

the crankshaft at the crankshaft pulley side.

Oil is drawn up through the oil pump strainer and

passed through the pump to the oil filter.

The filtered oil flows into two paths in cylinder block.

In one path, oil reaches the crankshaft journal bear-

ings.

Oil from the crankshaft journal bearings is supplied to

the connecting rod bearings by means of intersecting

passages drilled in the crankshaft, and then injected

from a small hole provided on the big end of connecting

rod to lubricate piston, rings, and cylinder wall.

In another path, oil goes up to the cylinder head and lu-

bricates rocker arms, valves and camshaft, etc., after

passing through the internal oilway of rocker arm

shafts.

An oil relief valve is provided on the oil pump. This

valve starts relieving oil pressure when the pressure

comes over about 3.3 kg/cm

(46.9 psi, 330 kPa). Re-

lieved oil drains back to the oil pan.
