ENGINE MECHANICAL (M13 ENGINE) 6A1-3
ENGINE LUBRICATION
The oil pump is of a trochoid type, and mounted on the crankshaft. Oil is drawn up through the oil pump strainer
and passed through the pump to the oil filter.
The filtered oil flows into 2 paths in cylinder block.
In one path, oil reaches the crankshaft journal bearings. 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
the big end of connecting rod to lubricate piston, rings, and cylinder wall.
In other path oil goes up to the cylinder head and lubricates valves and camshafts, etc., after passing through
the internal oilway of camshafts.
An oil relief valve is provided on the oil pump. This valve starts relieving oil pressure when the pressure exceeds
about 400 kPa (4.0 kg/cm
2, 56.9 psi).

DISASSEMBLY AND REASSEMBLY
Disassemble and reassemble fuel pump assembly, noting the fol-
lowings.
When removing fuel level sensor (3), press snap-fit part (4)
and slide it in the arrow direction as shown in figure.
When installing fuel level sensor to housing, fit fuel level sen-
sor securely.

4. Housing 9. Bracket
CAUTION:
While removing fuel level gauge, do not contact resis-
tor plate (1) or deform arm (2). It may cause fuel level
gauge to fail.
When removing grommet from fuel tube or bracket sub
assembly, be very careful not to cause damage to
grommet installed section (sealed section in bore).
Should it be damaged, replace it with new one, or fuel
will leak from that part.

ENGINE AND EMISSION CONTROL SYSTEM 6E1-5
AIR INTAKE SYSTEM
The main components of the air intake system are air cleaner (1), air cleaner outlet hose (2), throttle body (3),
idle air control valve (4) and intake manifold (5).
The air (by the amount corresponding to the throttle valve (6) opening and engine speed) is filtered by the air
cleaner (1), passes through the throttle body (3), is distributed by the intake manifold (5) and finally drawn into
each combustion chamber.
When the idle air control valve (4) is opened according to the signal from ECM, the air (7) bypasses the throttle
valve (6) through bypass passage and is finally drawn into the intake manifold (5).
