OHV and HCS engines

OHV and HCS engines

The 1.1 litre and 1.3 litre OHV engines are of four-cylinder, in-line overhead valve type (hence OHV), mounted transversely together with the transmission, at the front of the car.

The crankshaft on 1.1 litre engines is supported in three shell type main bearings, whereas the 1.3 litre unit features a five main bearing crankshaft. Apart from this difference and other minor alterations, the two engines are virtually the same in design and construction.
