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

When driving (part/full throttle), the servo motor controls the throttle valve in line with the
various load states and according to the input signals from the pedal value sensor according to
the input signals from the pedal value sensor according to the position of the accelerator pedal.
The function of the EA (electronic accelerator) in the ECM determines the opening angle of the
throttle valve through the throttle actuator.

TORQUE ON DEMAND
RODIUS 2005.07
3240-01
2. GENERAL DESCRIPTION
TOD system means the full time 4WD system and the registered trade mark of Borg Warner.
TOD is an abbreviation of Torque On Demand.
TOD (Torque On Demand) system, which is superior than existing Full Time 4WD, checks the
road surface and vehicle conditions via various sensors and, subsequently, according to the
situations and conditions, distributes the most optimal driving force to front wheels and rea
r
wheels by activating the electro-magnetic clutch located inside of TOD Transfer Case.
TOD receives the speed signals from speed sensors installed in front axle and rear axle, the
TPS signals from engine, and the operating signals from ABS control unit via CAN.
Based on these data, TOD control unit controls the electro-magnetic clutch to distribute the
3:97 ~ 44:56 of driving force to front wheels and rear wheels.
The conventional system uses “FR driving” (theoretically, the 100 % of driving force is
transferred to rear wheels) on normal paved road.
When the system detects a slip in the rear wheels, a proper percentage of driving force is
transferred to front wheels.
TOD control unit receives the wheel speed signals from the speed sensors in propeller shaft o
f
transfer case and engine output information from the engine control unit.
TOD control unit changes the pressure force of the electromagnetic clutch based on the
analyzed data.
1) Distribution of Driving Force According to Road Surface
On normal road surface ▶
In vehicle with existing part time transfer case, when a driver turns the steering wheel to park in
the 4WD mode, the vehicle may halt sensation of tight corner braking phenomena. However, in
vehicle with TOD system, this phenomena does not occur and the driving force is properly and
automatically distributed.
On paved road with high speed ▶
Driving at high speed on roads such as highway mainly uses rear wheels as driving wheel.
At this moment, some of torques is also distributed to front wheels so that the vehicle could
maintain safe ground grab capacity against side winds and rain.
Distribution ratio: 15 % for front wheels and 85% for rear wheels.

1. PROPELLER SHAFT GENERAL INFORMATION
The propeller shaft transfers the power through
the transmission and transfer case to the
front/rear axle differential carrier (final reduction
gear). It is manufactured by a thin rounded steel
pipe to have the strong resisting force against
the torsion and bending. Both ends of propelle
r
shaft are connected to the spider and the cente
r
of propeller shaft is connected to the spline to
accommodate the changes of the height and
length. The rubber bushing that covers the
intermediate bearing keeps the balance of rea
r
propeller shaft and absorbs its vibration.
