FUEL TANK
FUEL SUPPLY13C-4
•A resin coating is treated on the underfloor fuel
line pipes, improving reliability.
•A fuel tank pump with low power consumption
has been adopted to reduce the alternator load.
•A plastic tank pump and gauge assembly is used
to reduce weight.
•The fuel line tube and fuel line hose are made of
the material, which does not allow fuel vapour to
pass through it as much as possible, so that the
vapour gas emission to the air is reduced.
FUEL TANK
M2134001000442
The fuel tank assembly consists of components such
as a fuel tank pump and gauge assembly, a fuel
high-pressure hose, a fuel tank hose, and a fuel tank,
and has the following features:
•The fuel tank is located underneath the rear seats
to improve safety at a collision.
•The fuel tank itself is made of a pre-coat galva-
nized steel sheet that contains no lead.
•The fuel tank pump is housed in the fuel tank to
improve collision safety.
•A fuel tank safety valve, which prevents fuel leak-
age when the vehicle banks or rolls over, is
located inside the fuel tank pump and gauge
assembly.
•The fuel high-pressure hose and fuel tank hose
are made of the material, which does not allow
fuel vapour to pass through it as much as possi
-
ble.
The fuel tank pump and gauge assembly consist of
the following components:
•Fuel tank pump
•Fuel tank gauge unit
•Fuel tank filter assembly
•Fuel pump pressure regulator <4A9>
•Fuel tank safety valve
•Fuel tank 2-way valve

ENGINE CONTROL
ACCELERATOR SYSTEMM2170003000310
For the accelerator system, an electronic throttle
valve control system has been adopted, eliminating
of an accelerator cable. This system detects the
amount of the accelerator pedal movement by using
a accelerator pedal-position sensor in the accelerator
pedal assembly for electronic control of the throttle
valve angle.

EMISSION CONTROL
GENERAL INFORMATION <4A9>M2171000100838
Although the emission control systems are basically
the same as those of the 4G1-Non-Turbo engine
used in the COLT, the following improvements have
been added.•The adoption of the catalytic converter just
beneath exhaust manifold realizes the earlier
activation.
•The adoption of the dual oxygen sensor has
increased reliability air/fuel ratio control.

Although the emission control systems are basically
the same as those of the 4G1-Non-Turbo engine
used in the COLT, the following improvements have
been added.
•The adoption of the catalytic converter just
beneath turbo charger and under the floor
increased the performance of the emission con

trols.
•The adoption of the check valve between the
purge control solenoid valve and the canister pro
-
tects the regurgitation as turbocharging.
