The fuel consumption figures in accordance with 1999/100 EC standards were determined during the course of homologation
tests which include:
- an urban cycle which includes a cold start followed by a simulated varied urban cycle.
- an extraurban cycle which includes frequent acceleration in all gears simulating normal out of town usage of the vehicle.
The speed varies between 0 and 120 km/h.
- the average combined consumption figure includes 37% of the urban cycle and 63% of the non-urban cycle.
The type of route, traffic conditions, driving style, weather conditions, trim level/equipment/accessories, presence of special
equipment and the state of the vehicle in general can lead to different fuel consumption figures from those established
using the above mentioned procedures.
The CO2 exhaust emissions (in g/km) are measured during the combined average cycle.

ENGINE MANAGEMENT SYSTEM
The Marea-Marea Weekend 1596 16v has a 4 cylinder in line engine, with 16 valves, 1596 cc, twin over­
head camshaft and a Marelli IAW 4EF integrated electronic injection/ignition system.
The fuel system differs from the one described for the 1581 16v "99 range" version through the addition
of several variants to make it compatible with the EEC Stage 3 EOBD regulations.
The main modifications to the system can be summarized as follows:
- Engine management control unit with IAW 4EF
- Catalytic converter near the exhaust manifold to take maximum advantage of the heat of the gases.
- Two Lambda senors, one upstream (front) and one downstream (rear) which check the quality of the
exhaust gases and the operation of the catalyzer.
- Adoption of a timing sensor on the inlet side timing pulley.

FUEL ANTI-EVAPORATION SYSTEM
The fuel anti-evaporation system has several improvements, compared with previous versions, aimed at
sealing the fuel vapours on the outside.
In particular, the following measures have been adopted:
- multi-purpose valve on the tank to prevent leaks.
- New anti-evaporation solenoid valve and the adoption of rapid attachment connectors for the anti-
evaporation system pipes.
- Plug on the fuel filler with attachment cable.
For further information on the fuel system, refer to publication: 507137.

LOCATION OF DIAGNOSTIC SOCKET
The diagnostic socket for the analysis of the en­
gine management system is located under the
junction unit in the dashboard. This socket also
makes the connection with the diagnostic equip­
ment (Examiner or other instruments) for the
other electronic control units on the vehicle.
In effect, it is a "standardized" 16-way diagnostic
socket which can be connected to the diagnostic
equipment using the "MPX97" adaptor.
