3Foreword



IntroductionIn line with strategy of Saipa Company for environmental protection and emission control, installation of new

injection fuel delivery system was begun on new products of the Company.

The implementation of this project has pawed the way for production of cars equipped with new system as

main products of Saipa Company to comply with the environmental standards.

The emission of pollutants from cars equipped with this system is decreased and, on the other hand, the

output and escalation of the engine is promoted. Also some parts such as ignition distributor, carburetor, …

in old fuel delivery systems are replaced with other parts like ECU, injector, double injection coil, fuel rail, ….

In addition to high service life, new system has more efficiency and the diagnosis and part replacement is

easier.

The SIEMENS injection kits were being used on Pride cares of KIA MOTORS products. Due to some defects

of the said kits, in collaboration with JOHNSON CONTROLS, the Company has begun installation of new

injection kits (JCAE S2000) on Pride Engines. Among the advantages of JCAE kits over Kia Motors' kits

are decrease in fuel consumption, elimination of ignition coil through application of DLI (Distributor – Less

Ignition) system, and use of Knock Sensor and, finally, the foregoing result in decrease in engine defects due

to kick and piston melting, adoption of the engine operation with the climatic conditions and fuels used in Iran,

elimination of the need to EGR system, application of external diagnostic system, use of Inertia Switch for

fuel pump circuit cut at the time of sever traffic accidents, use of MIL (Malfunction Indicating Lamp) system for

diagnosis of defects by the driver, …..

14 Introduction of the System

A microprocessor is placed in Fuel Delivery Control Unit (JCAE S2000). The microprocessor and all its rel-

evant parts have been assembled on a printed circuit. The needed air intake is adjusted by throttle valve,

which in turn is controlled by the driver.

For the purpose of optimization of operations of the system during all times and under all conditions, ECU

controls the operations of ignition coil and injector.

The engine management system also adjusts the air intake through controlling the throttle position. Throt-

tle control also promotes the capabilities of driver and starting with a closed throttle will be easy.

The excess fumes of fuel tank are also sent to intake air manifold. The engine control system controls the

canister purge valve and the process of transfer of the excess fume is done without affecting the capability

of the driver (through the closed circuit of the system).

Electronic Control Unit (ECU)As you see in the following figure, the unit receives signals from a number of sensors and transforms them

to the digital display.

A/D is an electronic circuit, which transforms the analog signals received from sensors to the digital ones.

The reason for use of A/D in ECU is that the microprocessor circuits are activated by digital signals.

The intake air manifold, in comparison with old carburetor engines, uses a new design which optimized

for increasing engine torque and power. The fuel delivery is done by four injectors (each delivers the fuel

to one of cylinders), which have been connected to fuel rail. At any time, two of these injectors are operat-

ing synchronous. The ignition is done by double ignition coils with four outlets which in turn consists two

coils.

The application of oxygen sensor (Lambda Sensor) together with catalyst manifold converter, result in

decrease in the pollutant emission.

Fuel Delivery SystemThe fuel delivery system used on Pride engine,

equipped with Johnson Controls injection system, is

of Multi Point Fuel Injection (MPFI) type.

The system consists of four injectors, which are sit-

uated immediately before intake valve and the fuel

is directly injected into intake manifold.

Because of mixed fuel control and taking the mix-

ture ratio, MPFI system operates in an optimum

way. The engine operation conditions are deter-

mined by ECU, which receives the needed signals

from different sensors and injectors. On the basis of

the received signals, the engine operation is con-

trolled and optimized.

Fuel delivery system consists of injectors, fuel

pump, pressure regulator, fuel filter, fuel rail, and

fuel ducts.

1-Fuel Pump

The pressure of fuel pump is more than the pres-

sure needed for fuel system; this eliminates fuel def-

icit, which commonly happens as a result of speed

change in the vehicle. The outlet duct is equipped

with a check valve that maintains the fuel pressure

at a fixed rate throughout the duct when the vehicle

is switched off.

Fuel pump is installed in the fuel tank and is floating

in the fuel at all times. This reduces pump noise and

does not allow formation of bubbles also protects

the pump against strokes of other objects.

The needed voltage for fuel pump to operate is 12

V, which is supplied through double relay and fuel

inertia switch as per following timing criterion:

-when the switch is on for 3 to 5 seconds, and

-at all times that the engine is running.

2-Fuel Filter

Fuel filter is located at the left hand of the engine

under brake booster and near the fuel rail.

The fuel passes through this filter and all the parti-

cles are removed from it, which is the first action for

protection of injectors.

The filters are capable to remove particles with 8 to

10 micron diameters and they should be replaced

every 20,000 kilometers of travel.

Another filter is placed in the tank, which should be

never lubricated.

Fuel Delivery System


17

3-Hoes and Fuel Delivery Line

The steel pipes of fuel delivery system and rub-

ber hoes are extended from the tank to the engine

where fuel filter is located. The fuel is transferred to

fuel rail through a rubber hoes which is fixed to the

rail by a clamp. The connection of fuel filter to fuel

rail and also fuel rail to the excess fuel return pipe is

by use of flexible rubber pipes and a clamp.

Note: Never lubricate the fuel carrying hoes (Fig-

ure …..).

4-Fuel Rail

Like Kia Motors’ injection fuel delivery system, in

this system the fuel rail is located at the center of

the engine in central space of air intake manifold

assembly near cylinder head and four injectors; fuel

pressure regulator and fuel intake and outflow hoes

are installed on it.

Fuel rail is fixed on air intake manifold by use of

screws. In fuel rail the pressured fuel is ready to be

delivered to the injectors; at the time of activation of

each of injectors, the fuel is entered into injector and

is injected in powdered form into intake port and,

eventually, into the cylinder.

5-Fuel Pressure Regulator

The fuel pressure regulator maintains the fuel pres-

sure rate in the fuel rail (at inlet of the injectors) at

a fixed level (3.5 bars) considering the air pressure

in the air intake manifold assembly. Consequently,

at all times, the fuel with a fixed pressure is ready at

inlet of the injectors and, notwithstanding different

conditions and speeds of engine, the fuel is deliv-

ered continuously. Also a check valve is installed on

the fuel delivery route above the fuel pump which

prevents from return of fuel into the tank; therefore,

the pressure is continuously maintained at a fixed

level. This will ease the start up of the engine and

prevents from formation of gas barrier in fuel deliv-

ery ducts.

6-Inertia Switch

Inertia Switch is installed on a special location of the

engine which has the minimum possible vibration.

This switch cuts-off the fuel pump circuit and other

actuators at the time of sever accidents. In vehicles

equipped with electric fuel pump, the continuous

fuel delivery, even at the time of sever accidents,

may result in fire accident.

20 Fuel Delivery System


21

7-Injector

The fuel delivery system of Pride engines is

equipped with Johnson Controls’ injection system of

MPFI type which for each cylinder there is an injec-

tor.

Injectors inject the fuel in powdered form into inlet of

cylinders. Injectors are located between fuel rail and

intake air manifold and are sealed by use of O rings

placed on both ends of them and are fixed on fuel

rail by clamps. At the time of activation of each of

injector, the fuel is injected into cylinder inlet in pow-

dered form. The injectors used in Johnson Controls

system are of Top-Feed type.



1-Throttle Body Assembly

1-1Throttle Body

On this body, butterfly valve, stepper motor and

throttle valve potentiometers have been installed,

which control the throttle position.

1-2Air By-Pass Valves (Stepper Motor)

In addition to intake air butterfly valve, throttle body

has an additional duct which the air is by-passed

through it. The amount of air intake through this

route, which is measured by an ECU, is controlled

by a stepper motor considering the operation condi-

tions of the engine for the following purposes:

1-To act as a strangler at the time of starting.

2-Adjust the idling speed at the time of engine over-

load (when cooler and other devices are on).

3-Regulate the air-fuel mixing process at the time

of idle speed.

4-Prevent from rapid blockage of air duct when the

driver, at high speeds, suddenly releases the accel-

erator pedal

1-3Throttle Valve Potentiometer

This potentiometer sends to ECU the instantaneous

position of throttle to be used for detection of idle

positions, total load and acceleration and speed re-

duction processes.

The feed voltage of the sensor is 5V which is sup-

plied by ECU

Air Delivery System

22 Air delivery system


23

2- Intake Manifold

The intake manifold assembly in Pride engine

equipped with injection system contains air intake

manifold, speed reduction duct, fuel rail, injectors,

throttle valve, pressure sensor, intake air tempera-

ture sensor, and end of brake booster hoes, canis-

ter valve and water temperature sensor.

Air delivery system


2-HT Leads

HT leads are used for connecting the ignition plugs

to the coils and combusting the fuel in cylinder.

The used HT leads are parasite resistant.

1-Ignition Coil

The ignition coil supplies the needed electric volt-

age for ignition plugs and contains four leads which

are connected to the ignition plugs through two in-

ternal coils.

The ignition in 1st and 4th and also in 3rd and 2nd

are simultaneous.

On the other words, the ignition plugs of both of

cylinders that one is in combustion phase and the

other one is in end of exhaust phase act simultane-

ously. The ignition time and duration of dowel time

are controlled as per data received from ECU. The

ignition coil is installed on cylinder head.

Double Ignition Coil System

24 Ignition System


25

In Johnson Controls system, the operation is con-

trolled and managed by use of an ECU (JCAE

S2000).

Based on signals that are received from different

sensors, ECU controls time and duration of fuel

injection by injectors, time and duration of ignition,

idle position of engine, the knocking level of engine

and also the operations of fuel fume emission con-

trolling equipment.

In addition, ECU also controls the operations of elec-

tric fuel pump and malfunction indicating system.

The ECU operates on the basis of an initial calibra-

tion that is done by the manufacturer considering

the engine and vehicle specifications.

The following parameters are monitored by ECU:

• Engine speed

• Manifold pressure and intake air temperature

• Throttle valve position

• Water temperature

• Vehicle speed

• Camshaft position

• Ratio of intake air to fuel

• Engine knocking level

• Air conditioning system function

• Battery voltage

ECU uses the above parameters to control the fol-

lowing functions:

• Time and duration of fuel injection

• Ignition time and dowel duration

• Idle working of engine

• Fuel pump operation

• Canister purge valve operation

• Fuel injection cut-off for prevention from elevation

of engine speed

• Malfunction indicating lamp operation

In addition, which data that are sent to ECU, are

used for displaying the following information:

ECU Operation under Different Condi-tions• ECU Operation at the Time of Starting

At the time of starting, ECU sends activation com-

mand to injectors in the form of pulse (stepper wave)

with a fixed width.

Consequently, the injectors inject the fuel alterna-

tively.

The amount of the injected fuel is determined by

taking into account the engine speed, water tem-

perature and also temperature and pressure of the

intake air. Also the excess air is determined by the

stepper motor and by use of the engine operation

parameters.

After starting, the idle speed is determined by use of

water temperature.

• ECU Operation in Different Engine Speeds

At the time of instantaneous change in engine

speed (acceleration and speed reduce), the dura-

tion of injection is determined by taking into account

the changes in the following parameters:

- engine speed (which is detected by engine speed

sensor)

- throttle valve position (is detected by throttle posi-

tion sensor)

- intake air pressure (is detected by intake air pres-

sure sensor)

- water temperature (is detected by water tempera-

ture sensor)

• ECU Operation at the Time of Fuel Injection

Cut-Off

A. At the time of speed reduction, when the driver

suddenly releases the accelerator pedal, ECU cuts-

off the fuel injection due to the following reasons:

- Fuel consumption reduction

- Reduction of pollutant emission

B. For the purpose of prevention from excess en-

gine speed elevation, the fuel injection is stopped

when the engine speed reaches around 5500 rpm.

• ECU Operation at the Time of Resume of Fuel

Injection

After fuel cut-off, when the engine speed reduces

to a safe level, the unit activates the fuel injection to

prevent form shot down.

ECU Memory

ECU has two kinds of memories:

- permanent memory

- RAM memory

The data on permanent memory are not cleared as

a result of power failure; this memory stores the ta-

bles of engine operation, thereby ECU processes

the signals that are received from different sen-

sors.

The RAM memory data are cleared a short time af-

ter power switch off.

26 Electronic control unit(ECU)


27

For the purpose of measurement of different param-

eters of engine operation, a number of sensors are

used in new fuel injection engines of Pride cars; the

operation and positions of these sensors are de-

scribed as follows:

1-Engine Speed Sensor

This sensor is installed on clutch case and meas-

ures engine speed and also TDC of 1st and 4th

cylinders and sends the signals to ECU. The fly-

wheel, which is connected to the crankshaft, moves

and, proportional to its speed, creates a magnetic

field and each speed has its own voltage, which is

sensed by this sensor and sent to ECU in the form

of signal.

The signals sent by this sensor are used by ECU for

processing several parameters including fuel injec-

tion, ignition time, etc.

2-Camshaft Sensor

This sensor determines the TDC position of 1st cyl-

inder and sends a signal to the ECU in different from

signals sent by engine speed sensor.

It is installed on camshaft.

Sensors

Sensors


3-Manifold Pressure and Intake Air Temperature

Sensor

This sensor continuously measures the data of

manifold pressure and intake air temperature and

sends the relevant signals to ECU.

The feed voltage of the sensor is 5 V, which is sup-

plied by ECU. Proportional to the measured pres-

sure by the sensor which is measured by a piezo-

electronic device installed in the sensor (the electric

resistant of the device is changed proportional to

the measured pressure).

The ECU uses the different return voltages, which

are changed as a result of different pressures, for

processing the following data:

- the intake air mass

- ratio of fuel to intake air, proportional to engine

load and ambient pressure

- advance ignition

The used resistant in the sensor is of NTC type (its

resistance is increased proportional to temperature

increase) and its operation range is between 40 to

50 ˚C. ECU uses the signals sent by this sensor for

processing the intake air mass.

4- Water Temperature Sensor

This sensor measures the temperature of cooling

water and sends the relevant data to ECU.

The sensor is equipped with NTC resistant and has

a connector with two supports.

28 Sensors


29

6-Oxygen Sensor

Oxygen sensor is installed on exhaust manifold in

outflow fumes duct between the engine and cata-

lytic converter.

This sensor measures the concentration of the fuel-

air mixture and sends the relevant signals to ECU.

ECU uses the signals sent by this sensor for

processing the following parameters:

- calculation of fuel and air mixture

- adjustment of fuel and air mixture for optimum op-

eration of the engine. The optimum operation indi-

ces of fuel-air mixture are stored in the permanent

memory of ECU and used for appropriate operation

of catalytic converter.

Proportional to the concentration of fuel-air mixture,

ECU receives a signal with a range of 0 – 1 Volt

from oxygen sensor and uses the same and the

indices in the permanent memory for adjusting the

fuel and air intake for proper operation of catalytic

converter.

- The lean mixture creates a Voltage equal to 0.1

Volt, and

- The over-rich mixture creates a Voltage equal to

0.9 Volt

5-Vehicle Speed Sensor

This sensor is installed on mileage indicator gear

of Pride car and creates a signal proportional to the

gearbox shaft speed and, as a result, measures the

vehicle speed.

Sensors


7-Knock Sensor

The sensor sends the signals of engine knock to the

ECU. The knock is a vibration, which is occurred as

a result of early combustion of the fuel-air mixture in

the cylinder.

In case of such occurrence in cylinder, the ECU

controls the engine advance by use of signals it re-

ceives from knock sensor and, simultaneously, in-

creases the fuel-air mixture ratio.

30 Sensors


31

2- Canister Purge Valve

The fuel fumes of fuel tank are recovered in canister

by use of canister purge valve which is in turn con-

trolled by ECU.

Whenever the valve is open, the fumes of canister

are transferred to the engine through air intake duct

and used in the cylinders

The following actuators are installed in the New

Fuel Delivery System of Pride cars for controlling

the engine operation conditions:

1- Double Relay

The relay carries out the electric feed of the injection

system under different conditions of engine opera-

tion including switch off, switch on and running.

Double relay is connected to the main power supply

wire by use of a 15-way connector and has three

phases of operation:

A. Switch Off

During switch off period, a 12 V currency is fed to

ECU through 10th terminal of the double relay for

storage of its data.

B. Switch On

In switch on position, ECU supplies the needed volt-

age for 2 to 3 seconds to the following parts:

- ECU

- Fuel pump

- Injectors

- Double ignition coil

- Canister purge valve

- Resistant of oxygen sensor heater

C. Running Position

In running position, the needed Voltage is supplied

to all the parts of the system.

DIAGNOSIS OF SYSTEM PARTS DEFECTS



This Chapter includes the procedure of defect di-

agnosis in Pride cars equipped with new fuel de-

livery system (Johnson Controls Kit). The probable

defects of injection system are detailed step by step

and the reader is provided with the appropriate ac-

tion in each step. Please note the following facts

prior to beginning diagnosis process:

• BOB is the initiatives of Break Out Box, or inter-

face connector; by using it you can easily access to

ECU pins. If you have not this tool, then use a pin;

insert the pin into the concerned wire and carry out

your needed tests.

• Please carry out the diagnosis process carefully

and allot to it appropriate time and follow the steps

and instructions carefully.

• Multi-meter (Ohmmeter, Voltmeter and Ampere

Meter) is an essential tool in diagnosis process of all

parts. It is evident that you have to be fully familiar

with the use of this tool before to begin to diagno-

sis.

• Never connect the wires carrying 12 DC current

to sensors and actuators!

• When the switch is on or the engine is running,

never cut the connector.

• ECU connector consists three parts: Black con-

nector (M1), Brown connector (CP), and Grey con-

nector (M2); please note that, at the time of connect-

ing the connector to ECU, in the first step connect

M1, then connect CP and, finally, connect M2 and

follow the reverse order at the time of disconnect-

ing: First M2, second: CP and third: M1.

• Please look at the ECU connector carefully to find

the appropriate wire and find the concerned pin us-

ing the signs; use figure on page 49 as a guide.

• Whenever you intend to measure ignition or com-

pressor systems, please note that the connectors

and injectors should be already disconnected.

• Whenever a defect is found by the diagnosis

equipment, the found defect is entered into the

memory of the equipment (error memory). After re-

moving the found defect, the error remains in the

memory and should be deleted by the equipment.

Therefore, please note that the errors should be

deleted at any time after removing of defects of

each step.

• Please note the following fact at the time of diag-

nosis operation on electric parts:

1- The battery should be fully charged, and

2- Never use the supply sources with more than

16 V DC currency!
