In a three-cylinder engine a power stroke occurs every 240 degrees (720В° Г· 3 = 240В°). In a one-, two-, or three-cylinder engine there are times when no power stroke is occurring.

At the end of one cylinder's power stroke another cylinder fires. A crossplane V8 engine gets a power stroke every 90 degrees: 720В° Г· 8 = 90В°, which is four power strokes for each revolution of the crankshaft.ДЄ given power stroke can last no more than 180 degrees of crankshaft rotation, so the power strokes of a four-cylinder engine are sequential, with no overlap. For a four-cylinder engine, 720В° Г· 4 = 180В° so there is a power stroke every 180 degrees, which is two power strokes per revolution of the crankshaft. Assuming an even firing engine, divide 720 degrees by the number of cylinders to determine how often a power stroke occurs. In a four-stroke cycle the engine fires every cylinder once every 720 degrees - each piston fires for every two rotations of the crankshaft. The five-cylinder engine's advantage over a comparable four-cylinder engine is best understood by considering power strokes and their frequency. This particular engine is found aboard a 29,000-tonne chemical carrier. The MAN B&W 5S50MC five-cylinder two-stroke diesel engine. In recent years the engine has been falling out of favour, with Volvo announcing in 2014 it would discontinue building them, for example. They were often used by middle-market brands seeking to extend their engine ranges into higher capacities without going for the six-cylinder option. The first production petrol straight-five was the 2.1 R5 introduced by Volkswagen Group in the Audi 100 towards the end of the 1970s, developments of which powered the Audi Quattro rally car. ДЄ straight-five engine did not see production for passenger cars until Mercedes-Benz introduced the OM617 diesel in 1974. This truck remained in production until 1950. The subsequent model became known as the 3RO and was used by both Italian and German armed forces during WW2.

Lancia of Italy developed a 5-cylinder diesel engine in the late 1930s for use in their RO truck series to replace the earlier 2-cylinder diesel and 3-cylinder petrol engines used. Henry Ford had an inline-five engine developed in the late 1930s to early 1940s for a compact economy car design, which never saw production due to lack of demand for small cars in the United States.
