Straight-five engines typically have a 72 degree crankshaft design.
[3] All two stroke straight-five engines are limited in having a single firing order for a given crank configuration; because a complete cycle occurs every 360 degrees, there is no chance to share piston phases without having simultaneous ignitions, so the straight-five is at no disadvantage in this case.
[6] The use of straight-five petrol engines in mass production cars only became truly viable with the advent of reliable fuel injection.
This is because of the unavoidable problems of a carburettor supplying an odd number of cylinders and the length of the inlet manifold between the carburetor varying greatly between cylinders at the ends of the engine and those nearer the carburetor.
Unlike other engine layouts, these problems are not easily solved by using multiple carburettors.
Built for the Italian and German armed forces during World War II and later for civilian usage, the truck remained in production until 1950.
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.
Audi has continued use of straight-five petrol engines (in both naturally aspirated and turbocharged versions) to the present day.
[14][15][16][17] For the year 1987 factory team tested a 735 kW (1000 hp) version of the inline-5 powered Audi S1 Sport Quattro.
