ENGINE EXHAUST SYSTEM
1. EXHAUST SYSTEM
When you are inspecting or replacing exhaust system components, make sure there is
adequate clearance from all points on the underbody to avoid possible overheating of the
floor panel and possible damage to the passenger compartment insulation and trim
materials. -
Check the complete exhaust system and the nearby body areas and trunk lid for broken,
damaged, missing or mispositioned parts, open seams, holes, loose connections, or othe
r
deterioration which could permit exhaust fumes to seep into the trunk may be an indication of a
problem in one of these areas. Any defects should be corrected immediately.
2. MUFFLER
Aside from the exhaust manifold connection, the exhaust system uses a flange and seal joint
design rather than a slip joint coupling design with clamp and U-bolts. If hole, open seams, o
r
any deterioration is discovered upon inspection of the front muffler and pipe assembly, the
complete assembly should be replace, the complete assembly should be replaced. The same
procedure is applicable to the rear muffler assembly.
Heat shields for the front and rear muffler assembly and catalytic converter protect the vehicle
and the environment from the high temperatures that the exhaust system develops.
3. CATALYTIC CONVERTER
When jacking or lifting the vehicle from the body side rails, be certain that the lift pads do
not contact the catalytic converter, as this could damage the catalytic converter. -
Use of anything other than unleaded fuel will damage the catalyst in the catalytic converter. -
The catalytic converter are emission-control devices added to the exhaust system to reduce
pollutants from the exhaust pipes.
The oxidation catalyst is coated with a catalytic material containing platinum and palladium,
which reduces levels of hydrocarbon (HC) and carbon monoxide (CO) from the exhaust gas.
The three-way catalyst has coatings which contain platinum and rhodium, which additionally
lower the levels of oxides of nitrogen (NOx).

3) Fuel System Specification
Use Only Unleaded Fuel Rated at 89 Octane or Higher ▶
Fuel quality and additives contained in fuel have a significant effect on power output, drivability,
and life of theengine.
Fuel with too low an octane number can cause engine knock.
Use of fuel with an octane number lower than 89 may damage engine and exhaust
system.
To prevent accidental use of leaded fuel, the nozzles for leaded fuel are larger, and will
not fit the fuel filler neck of your vehicle. -
-
Do Not Use Methanol ▶
Fuels containing methanol (wood alcohol) should not be used in vehicle.
This type of fuel can reduce vehicle performance and damage components of the fuel system.
Use of methanol may damage the fuel sys-tem. -
For safety reasons (particularly when using noncommercial fueling systems) fuel containers,
pumps and hoses must be properly earthed.
Static electricity build up can occur under certain atmospheric and fuel flow conditions i
f
unearthed hoses, particularly plastic, are fitted to the fuel-dispensing pump.
It is therefore recommended that earthed pumps with integrally earthed hoses be used, and
that storage containers be properly earthed during all noncommercial fueling operations.Vehicle Fueling from Drums or Storage Containers ▶

2. FUEL SYSTEM
The function of the fuel metering system is to deliver the correct amount of fuel to the engine
under all operating conditions.
The fuel is delivered to the engine by the individual fuel injectors mounted into the intake
manifold near each cylinder.
The main fuel control sensors are the Mass Air Flow (MAF) sensor and the oxygen (O2)
sensors.
The MAF sensor monitors the mass flow of the air being drawn into the engine.
An electrically heated element is mounted in the intake air stream, where it is cooled by the
flow of incoming air.
Engine Control Module (ECM) modulates the flow of heating current to maintain the
temperature
differential between the heated film and the intake air at a constant level. The amount o
f
heating current required to maintain the temperature thus provides an index for the mass ai
r
flow.
This concept automatically compensates for variations in air density, as this is one of the
factors that determines the amount of warmth that the surrounding air absorbs from the heated
element. MAF sensor is located between the air filter and the throttle valve.
Under high fuel demands, the MAF sensor reads a high mass flow condition, such as wide
open throttle.
The ECM uses this information to enrich the mixture, thus increasing the fuel injector on?time,
to provide the correct amount of fuel. When decelerating, the mass flow decreases.
This mass flow change is sensed by the MAF sensor and read by the ECM, which then
decreases the fuel injector on?time due to the low fuel demand conditions.
The O2 sensors are located in the exhaust pipe before catalytic converter.
The O2 sensors indicate to the ECM the amount of oxygen in the exhaust gas, and the ECM
changes the air/fuel ratio to the engine by controlling the fuel injectors.
The best air/fuel ratio to minimize exhaust emissions is 14.7 to 1, which allows the catalytic
converter to operate most efficiently. Because of the constant measuring and adjusting of the
air/fuel ratio, the fuel injection system is called a “closed loop” system.
The ECM uses voltage inputs from several sensors to determine how much fuel to provide to
the engine.
The fuel is delivered under one of several conditions, called ‘‘modes”.

ENGINE CONTROL SYSTEM
1) Starting Mode
When the ignition is turned ON, the ECM turns the fuel pump relay on for 1 second.
The fuel pump then builds fuel pressure.
The ECM also checks the Engine Coolant Temperature (ECT) sensor and the Throttle Position
(TP) sensor and determines the proper air/fuel ratio for starting the engine.
This ranges from1.5 to 1 at -36°C (-33°F) coolant temperature to 14.7 to 1 at 94°C
(201°F) coolant temperature.
The ECM controls the amount of fuel delivered in the starting mode by changing how long the
fuel injector is turned on and off.
This is done by ‘‘pulsing” the fuel injectors for very short times.

2) Run Mode
3) Open Loop
When the engine is first started and it is above 690 rpm, the system goes into “open
loop” operation. In “open loop”, the ECM ignores the signal from the O2S and calculates
the air/fuel ratio based on inputs from the ECT sensor and the MAF sensor.
The ECM stays in “open loop” until the following conditions are met:
The O2 has a varying voltage output, showing that it is hot enough to operate properly.

A specific amount of time has elapsed after starting the engine. -

4) Closed Loop
The specific values for the above conditions vary with different engines and are stored in the
Electronically Erasable programmable Read-Only Memory (EEPROM).
When these conditions are met, the system goes into “closed loop” operation. In “closed
loop”, the ECM calculates the air/fuel ratio (fuel injector on-time) based on the signals
from the O2 sensors.
This allows the air/fuel ratio to stay very close to 14.7 to 1.
5) Acceleration Mode
The ECM responds to rapid changes in throttle position and airflow and provides extra fuel.
The ECM responds to changes in throttle position and airflow and reduces the amount of fuel.
When deceleration is very fast, the ECM can cut off fuel completely for short periods of time.
