CATALYTIC EXHAUST
TRAINING MANUAL: JET FORCE: Page : 8/43

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
Composition of the catalytic block
The catalytic block is composed of a metal grid, impregnated with precious metals, rolled inside a steel
tube forming a honeycomb.
1. Metal grid
2. Steel tube
3. Honeycomb
4. Impregnation with precious metals (Platinum, palladium, rhodium, etc...)

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).
1. Cylinder head
2. Petrol injector
3. Air injector
4. Spark plug

DIAGNOSTIC
TRAINING MANUAL: JET FORCE: Page : 12/43
Reproduction or translation, even partial, is forbidden without the written consent of Peugeot Motocycles
DIAGNOSTIC
Warning
A LED comes on on the instrument
cluster to warn the rider of a fault on the
injection and ignition system ELECTRICS
Fault processing principle
Three priority levels
1 - “ serious safety ” fault: fault
memorised in ECU and LED stays on
2 - “ serious ” fault: fault memorised in
ECU and LED flashes
3 - “ minor ” fault: fault memorised in the
ECU without lighting the warning light
Note: When the ignition is turned on, the
LED stays on to check it is functioning
correctly
Self-diagnostic principle
