WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
For the descriptions (items) not found in this section, refer to the same section of the Service Manual
mentioned in FOREWORD of this manual.

6E2-6 ENGINE AND EMISSION CONTROL SYSTEM (SEQUENTIAL MULTIPORT FUEL INJECTION FOR H27 ENGINE)
Air Intake System
The main components of the air intake system are air cleaner, mass air flow sensor, air cleaner, intake air pipe,
throttle body, intake collector, idle air control valve and intake manifold.
The air (by the amount corresponding to the throttle valve opening and engine speed) is filtered by the air
cleaner, passes through the throttle body, is distributed by the intake manifold and finally drawn into each com-
bustion chamber.
When the idle air control valve is opened according to the signal from ECM (PCM), the air bypasses the throttle
valve through bypass passage and is finally drawn into the intake manifold.

ENGINE AND EMISSION CONTROL SYSTEM (SEQUENTIAL MULTIPORT FUEL INJECTION FOR H27 ENGINE) 6E2-7
Fuel Delivery System
The fuel delivery system consists of the fuel tank, fuel pump, fuel filter, fuel pressure regulator, delivery pipe and
fuel injectors.
The fuel in the fuel tank is pumped up by the fuel pump, filtered by the fuel filter and fed under pressure to each
injector through the delivery pipe.
As the fuel pressure applied to the 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
intake port of the cylinder head when the injector opens according to the injection signal from ECM (PCM).
The fuel relieved by the fuel pressure regulator returns through the fuel return line to the fuel tank.
