CATALYTIC EXHAUST

CATALYTIC EXHAUST
Composition of the catalytic exhaust system:
The catalytic exhaust system is distinguished by the fitting of a catalyser cone just after the exhaust inlet
cone. All the exhaust gases are fed through the catalyser cone.

1. Exhaust pipe
2. Heat insulation
3. Catalyser cone
FUNCTIONING OF THE CATALYTIC CONVERTER EXHAUST
Definition
The catalyser is a block used to facilitate and acceleration chemical reactions without being modified itself

INJECTION SYSTEMS / TSDI IGNITION

Introduction
Of the throttle angle / engine speed type, the SYNERJECT system was developed for the following
applications:
Monopoint sequential injection
Static timing
The system basic principle consists in measuring the engine speed and load ( throttle opening ) in order to
determine the optimum quantity of fuel injected
This system is used on the JET FORCE 50 scooter and requires NO ADJUSTMENT
(Ditto Looxor and Elystar 50 cc).

INTRODUCTION
Of the throttle angle / engine speed type, the EFI system was developed for the following applications:
Monopoint sequential injection
Static timing
The system basic principle consists in measuring the engine speed and load ( throttle opening ) in order to
determine the optimum quantity of fuel injected
This system is used on the JET FORCE 125 scooter and requires NO ADJUSTMENT
(Ditto Elystar 125 150 cc)
ADVANTAGES OF THE INJECTION SYSTEM
Peugeot Motocycles has developed a new generation of engines. Cleaner, more reliable, more economical,
these engines comply with the most stringent emission control standards, whilst maintaining a very high
level of performance. There are many advantages :
- Reduction in polluting emissions
- Reduction in fuel consumption
- Improved rider comfort
Fuel injector
The injectors are of the electro-magnetically operated single-jet type
The ECU electrical pulses generate a magnetic field in the magnet winding, the core is attracted, the
injector plate raised off its seat and releases the pressurised fuel upline of the inlet valve

50 cc ignition on or engine running

The lighting relay (11) is powered when the ignition is on via terminals 1 and 3
Over terminal 2 of the relay, the control coil is earthed through the starter motor (13)
The power circuit, via relay terminal 5 powers:
- The rear and front sidelights
- The number plate light (50cc IL and 125cc)
- The instrument cluster lighting
- Power supply to the Dip/Full Beam control (4) and the headlight flasher for the 125 cc

50 cc starting function

Press starter button (3):

Pressing the starter button (3) earths the starter relay winding (12) which then powers:
- The starter motor
- Terminal 2 of the lighting relay (11)
The potential on the coil two terminals is the same (12 V):
- the magnetic field disappears
- the relay blade opens
- the lighting circuit is no longer powered
Note: All of the battery power will be used by the starter motor
Without pressing the starter button (3):
The magnetic field in the starter relay coil (12) disappears the power circuit opens:
- Terminal 2 on the lighting relay is earthed through the starter motor
- The lighting circuit is powered

TRANSPONDER IMMOBILISER

TRANSPONDER IMMOBILISER
Precautions:
Check that the diagnostic plug jumper is fitted. The jumper provides the link between the immobiliser
module and the injection/ignition ECU, and is essential to be able to start the engine
If the jumper is not fitted, the transponder LED diagnostic is always the same (no link between the
immobiliser and the ECU)
Note: Fitting of a 5 k resistive suppressor along with a resistive spark plug is essential for the proper
functioning of the engine
System programming
The machine is supplied with a red key (master) and a black key
The system is programmed in the factory
It is possible to program up to 7 black keys
The key memory procedure is the same as the AEC400 and ACI100 system
Reminder of the key memory procedure
1. Using the red key, set the ignition to on, and when the LED lights, turn off the ignition
2. Within a maximum of 15 seconds of cutting off the ignition with the red key, turn on the ignition with
the black key, and when the LED comes on turn off the ignition (repeat the operation for each black key
to be memorised (maximum of 7 black keys))
3. Within a maximum of 15 seconds of turning off the ignition with the last key memorised, turn on the
ignition with the red key, and when the LED comes on, turn off the ignition
Key memory check
Using the red key, turn on the ignition, the LED on the instrument panel comes on for 0.5 seconds and
flashes a number of times. The number of flashes indicates the number of keys memorised, including the
red key
Additional information
Before carrying out any work on the transponder immobiliser, have the machine red key and black key to
hand
If the engine will not start, a first diagnostic may be carried out using the LED before checking the other
parts of the ignition system
Note: Do not remove the diagnostic plug jumper
In case of a fault, do not use an immobiliser module or ECU from another machine to carry out tests. The
keys, immobiliser module and ECU programmed on another machine form an assembly, are linked by a
code and must under no circumstances be separated
Important : If an ECU is changed without memorising the keys, do not turn on the ignition more than 16
times if the diagnostic jumper is disconnected as beyond this number, the ECU immobiliser function is
erased.

- Press for >5s to erase the symbol
Fuel gauge self-diagnostic
If the fuel system is cut off from the fuel gauge, when the ignition is turned on, the 8 LEDs light one after
the other
Gauge functioning (8s timer)
8 LEDs represent a full tank (10 ohms)
2 LEDs flash (75 ohms)
1 LED flashes (98 ohms)
8 LEDs flash (R> 87 ohms) means an empty tank
