6E1-4 ENGINE AND EMISSION CONTROL SYSTEM (TBI FOR G10)
The main components of this system are fuel tank,
fuel pump, fuel filter, throttle body (including fuel injec-
tor, fuel pressure regulator and idle speed control ac-
tuator), fuel feed line, fuel return line and air cleaner.
The fuel in the fuel tank is pumped up by the fuel
pump, filtered by the fuel filter and fed under pressure
to injector installed in throttle body. As the fuel pres-
sure applied to the fuel injector (the fuel pressure in
the fuel feed line) is always kept a certain amount
higher than the pressure in the intake manifold by the
fuel pressure regulator, the fuel is injected into the
throttle body in conic dispersion when the injectoropens according to the injection signal from ECM.
The fuel relieved by the fuel pressure regulator re-
turns through the fuel return line to the fuel tank.
The injected fuel is mixed with the air which has been
filtered through the air cleaner in the throttle body. The
air/fuel mixture is drawn through clearance between
throttle valve and bore.
Then the intake manifold distributes the air/fuel mix-
ture to each combustion chamber.
For the structure and operation of the fuel tank and fil-
ter, refer to SECTION 6C “ENGINE FUEL”.

REMOVAL
NOTE:
Use care when handling fuel injector especially not to damage
filter and its needle.
Also, because injector is an electrical component, it should
not be immersed in any type of liquid solvent or cleaner, or it
may get damaged.
1) Relieve fuel pressure, referring to Section 6.
2) Disconnect battery negative cable at battery.
3) Remove air cleaner assembly referring to Section 6A.
4) Remove air cleaner mounting stay from throttle body.
5) Remove injector wire and then remove fuel injector from throttle
body.
INSPECTION
Check fuel injector filter for evidence of dirt and contamination. If
present, clean and check for presence of dirt in fuel lines and fuel
tank.
INSTALLATION
1) Apply thin coat of spindle oil or gasoline to new upper and lower
O-rings, install lower O-ring and upper O-ring to injector.
2) Install injector by pushing it straight into fuel injector cavity.
Never turn injector while pushing it.

6E2-6 ENGINE AND EMISSION CONTROL SYSTEM (SFI FOR G13)
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 accord-
ing to the signal from ECM (PCM), the air (7) by-
passes the throttle valve (6) through bypass passage
and is finally drawn into the intake manifold (5).
