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).

FUEL DELIVERY SYSTEM
The fuel system consists of fuel tank (1), fuel pump (2) (with built-in fuel filter (3) and fuel pressure regulator (4)),
delivery pipe (5), injectors (6) and fuel feed line (7).
The fuel (8) in the fuel tank (1) is pumped up by the fuel pump (2), sent into delivery pipe (5) and injected by the
injectors (6).
As the fuel pump assembly is equipped with built-in fuel filter (3) and fuel pressure regulator (4), the fuel (8) is fil-
tered and its pressure is regulated before being sent to the delivery pipe (5).
The excess fuel from fuel pressure regulation process is returned back (9) into the fuel tank.
Also, fuel vapor generated in fuel tank is led through the fuel vapor line (10) into the EVAP canister (12).
FUEL PUMP
An in-tank type electric pump has been adopted for the fuel pump
(1). Incorporated in the pump assembly are;
Tank pressure control valve (2) which keeps the pressure in
the fuel tank constant, and prevents the fuel from spouting
and tank itself from being deformed.
Relief valve (3) which prevents the pressure in tank from ris-
ing excessively.
Fuel cut valve (4) which closes as the float rises so that the
fuel will not enter the canister when the fuel level in the tank
rises high depending on the fuel level in the tank and the
vehicle tilt angle.
Also, a fuel filter (5) and a fuel pressure regulator (6) are included
and a fuel level gauge (7) is attached.
Addition of the fuel pressure regulator (6) to the fuel pump makes
it possible to maintain the fuel pressure at constant level and
ECM controls compensation for variation in the intake manifold
pressure.
