23-32BODY - Seat Belts
OPERATION OF AUTOMATIC SEAT BELTS
The operation of the Automatic Seat Belts is as follows.
(1) The belts fasten itself around the occupant when the front
door is closed with the ignition switch in the “ON” position.
(2) The belts release itself from the occupant when the front
door is opened with the ignition switch in the
*“ON” or
“LOCK” or “ACC” position.
(3) The belts cease to fasten itself around the occupant if the
ignition switch is turned to “LOCK” or “ACC” or when the
front door is opened during the belt motion.
(4) The belts for the driver’s and front passenger’s seats
operate independently of each other.

SWITCHOVER MECHANISM
The
ELR/ALR switchover mechanism is installed at the re
tor for the lap belt for the front passenger’s seat,
The component is an assembly supply item, and so is not to be
disassembled. Its construction and operation are, however, as
described below.
Gear
B is coupled with the shaft of the retractor; it rotates in ::the counterclockwise direction when the belt is pulled out.
Gear A is meshed with gear
B, and revolve in the same
direction as gear
B.The illustration
(19PO373) shows the condition when the belt is
completely rewound.
When the belt is pulled out completely, gear A revolves about
three times, and the gear A cam contacts rod A, thereby
pressing rod A. Rod A then presses the stopper, and the
stopper presses the sub
pawl.When the sub pawl is pressed, the internal lock mechanism
functions, and the belt pull-out motion becomes lock, thus
becoming ALR.
When the belt
is rewound about 600 mm (23.6 in.) from the
completely pulled-out position, gear A revolves in the clockwise
direction. with the result that the cam of gear A contacts rod
6and causes rod
B to be pressed.
Rod
B then presses the stopper, thus causing the sub pan -return. thereby unlocking the lock and making pull-out
freti.thus becoming ELR.

25-2EMISSION CONTROL SYSTEMS - General Information
GENERAL INFORMATION
There are three sources of vehicle exhaust emis-
sions generated: the exhaust gases resulting from
combustion, the blow-by gases generated within
the crankcase, and the evaporative emissions
generated from the fuel tank and other components
of the fuel line.
The emissions-control system, which is designed to
control the discharge of these exhaust gases into
the atmosphere, is composed of the following
system components.
(1) Exhaust emission control system
(2) Crankcase emission control system
(3) Evaporative emission control system
R258A’The exhaust emissions-control system reduces the
amount of carbon monoxide, hydro carbon and
oxides of nitrogen in the exhaust gases by adding
the exhaust gas recirculation device and the cataly-
tic converter to fundamental improvements such as
improvement of the combustion chamber and the
camshaft, as well as other improvements to the
engine such as feedback control of the air/fuel ratio
by the electronically controlled fuel injection sys-
tem.
The crankcase emissions-control system is a closed
type so that blow-by gases are not discharged out to
the atmosphere. The evaporative emissions-control
system is the canister type; vapors that are gener-
ated within the fuel tank are introduced into the
intake manifold and are combusted so that they are
not emitted out to the atmosphere.

AIR-FUEL MIXTURE RATIO CONTROL
SYSTEMThe
MPI system is a system which employs the signals from
the oxygen sensor to activate and control the injector installed
at the each cylinder head thus precisely regulating the air-fuel
mixture ratio and reducing emissions,
This in turn allows the engine to produce exhaust gases of the
proper composition to permit the use of a three-way catalytic
converter. The three-way catalytic converter is designed to
convert the three pollutants
(1) hydrocarbons (HC), (2) carbon
monoxide (CO), and
(3) oxides of Nitrogen (NOx) into harmiess
substances.There are two operating modes in the
MPI system:
(1) Open Loop
Air-fuel ratio is controlled by information programmed into
the engine control unit at manufacture.
(2) Closed Loop
Air-fuel ratio is varied by the engine control unit based on
information supplied by the oxygen sensor.
NOTEFor detailed information concerning the
MPI system, refer
to Fuel System.

The overfill limiter consists of a pressure valve and a vacuum
valve. The pressure valve is designed to open when the fuel
tank internal pressure has increased over the normal pressure
and the vacuum valve opens when a vacuum has been
producted in the tank.
FUEL CHECK VALVE
The fuel check valve is used to prevent fuel leaks if the vehicle
rolls over. This valve is connected in the fuel vapor line
(between canister and overfill limiter) and is installed on thefirewall.
The fuel check valve contains two balls, as shown in the
illustration. Under normal conditions, the fuel vapor passage in
the valve is opened, but if roll-over occurs one of the balls
closes the fuel passage, thus preventing fuel leaks.
FUEL FILLER CAPThe fuel filler cap is equipped with a relief valve to prevent the
escape of fuel vapor into the atmosphere.
