Alfa-Sud Flat Four Engine 740031

The new Alfa-Sud engine is a 4-cyl, liquid-cooled “boxer” type layout with a single overhead camshaft for each bank.

Discussed in this paper are some of the design approaches used in meeting the criteria of a high-performance, small-displacement engine for a subcompact sports sedan. Bulk reduction during the design stage is outlined, along with results of crankshaft load studies. Serviceability was one of the criteria affecting the design, as is shown by the interesting valve adjustment system.

The appendixes contain crankshaft load data and illustrations describing design, assembly, and service features.
