Camshaft Position Control (VVT Variable Valve Timing) System DescriptionS7RS0B1401002
System Description
The VVT system is an electronic control system which continuously vary and optimize the intake valve timing in
response to the engine operating condition.
The optimized intake valve timing produce such an air intake with high efficiency that both the higher power generation
and lower fuel consumption can be attained in the whole engine speed range from low to high. In the area of the
average engine load, low emission of nitrogen oxides (NOx) and high fuel efficiency can also be attained by making
the valve opening overlap between the intake and exhaust valves longer.
For the brief of the system operation, the intake valve timing is varied by the cam timing sprocket (1) which varies the
rotational phase between the intake camshaft (3) and sprocket . The rotor (2) in the cam timing sprocket is actuated by
switching or adjusting the hydraulic pressure applied to the chambers for the timing advancing (7) and/or retarding (6).
To switch or adjust the hydraulic pressure appropriately, ECM operates the oil control valve (12) with detecting the
engine speed, intake air value, throttle opening, engine coolant temperature and camshaft position (angle).

Engine Lubrication System
General Description
Engine Lubrication DescriptionS7RS0B1501001
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 two paths in cylinder block.
The filtered oil is passed to the passage in heat
exchanger and cylinder block to piston cooling valve of
oil gushed to the lower side of piston. 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 cran
kshaft, and then injected
from the big end of connecting rod to lubricate piston,
rings and cylinder wall.
In the other path oil goes up to the cylinder head and
lubricates valves and camshafts, etc., after passing
through the internal oil way of camshafts.
An oil relief valve is provided on the oil pump. This valve
starts relieving oil pressure when the pressure exceeds
about 350 kPa (3.5 kg/cm
2, 49.8 psi).

Precautions
Precautions on Fuel System ServiceS7RS0B1700001
WARNING!
Before attempting service of any type on fuel system, the following should be always observed in
order to reduce the risk of fire and personal injury.
• Disconnect negative cable at battery.
• Do not smoke, and place no smoking signs near work area.
• Be sure to have CO
2 fire extinguisher handy.
• Be sure to perform work in a well-ventilated area and away from any open flames (such as gas hot heater).
• Wear safety glasses.
• To relieve fuel vapor pressure in fuel tank, remove fuel filler cap from fuel filler neck and then
reinstall it.
• As fuel feed line is still under high fuel pr essure even after stopping engine, loosening or
disconnecting fuel feed line directly may cause dangerous spout of fuel. Before loosening or
disconnecting fuel feed line, make sure to relieve fuel pressure referring to “Fuel Pressure Relief
Procedure”.
• A small amount of fuel may be released when the fuel line is disconnected. In order to reduce the risk of personal injury, cover a shop cloth to the fitting to be disconnected. Be sure to put that cloth
in an approved container after disconnecting.
• Never run engine with fuel pump relay disconnected when engine and exhaust system are hot.
• Note that fuel hose connection varies with each type of pipe. Be sure to connect and clamp each hose correctly referring to “Fuel Hose Disconnecting and Reconnecting”.
After connecting, make sure that it has no twist or kink.
• When installing inje ctor or fuel feed pipe, lubr icate its O-ring with gasoline.
General Description
Fuel System DescriptionS7RS0B1701001
CAUTION!
This engine requires the unleaded fuel only.
The leaded and/or low lead fuel can result in
engine damage and reduce the effectiveness
of the emission control system.
The main components of the fuel system are fuel tank,
fuel pump assembly (with fuel filter, fuel level gauge, fuel
pressure regulator, fuel feed line and fuel vapor line.
For the details of fuel flow, refer to “Fuel Delivery System
Diagram”.
Fuel Delivery System DescriptionS7RS0B1701002
The fuel delivery system consists of the fuel tank, fuel
pump assembly (with built-in f uel filter and fuel pressure
regulator), delivery pipe, injectors and fuel feed line.
The fuel in the fuel tank is pumped up by the fuel pump,
sent into delivery pipe and injected by the injectors.
As the fuel pump assembly is equipped with built-in fuel
filter and fuel pressure regulator, the fuel is filtered and
its pressure is regulated before being sent to the feed
pipe.
The excess fuel at fuel pressure regulation process is
returned back into the fuel tank.
Also, fuel vapor generated in fuel tank is led through the
fuel vapor line into the EVAP canister.
For system diagram, refer to “Fuel Delivery System
Diagram”.

Fuel Pump DescriptionS7RS0B1701003
The fuel pump (1) is an in-tank type electric pump.
Incorporated in the pump assembly are;
a fuel filter (2) and a fuel pressure regulator (3) are
included and a fuel level gauge (4) is attached.
Addition of the fuel pressure regulator to the fuel pump
makes it possible to mainta in the fuel pressure at
constant level and ECM controls compensation for
variation in the intake manifold pressure.
