This latter term,however, is used principally todistinguish it from a latermodification in which theseries of operations is com-pleted in two strokes of thepiston, and the latter form istherefore called two-cycleengine. The series of operationswhich takes place in the four-cycle engine is as follows:Suppose the engine to be avertical one, as that is theform quite generally employedfor marine purposes.
