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.
