Editing Straight-five engine (section)

=== Carburettors and fuel injection ===
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.

[[Diesel engine]]s have always used fuel injection, therefore large displacement straight-five diesel engines were commonly seen decades before straight-five petrol engines.
