1 General information
The engine is of four-cylinder, in-line, single
overhead camshaft type (see illustration). It is
mounted longitudinally at the front of the car.
Three versions are available: 1.8 litre
carburettor, 2.0 litre carburettor and 2.0 litre
fuel-injection.
The crankshaft incorporates five main
bearings. Thrustwashers are fitted to the
centre main bearing in order to control
crankshaft endfloat.
The camshaft is driven by a toothed belt
and operates the slightly angled valve via cam
followers which pivot on ball-pins.
The auxiliary shaft, which is also driven by
the toothed belt, drives the distributor, oil
pump and on some models the fuel pump.
