A row contains an odd number of cylinders, so an even number indicates a two- or four-row engine. Motor cycles commonly have from one to four cylinders, with a few high performance models having six.

In the case of a piston engine such as the engine in a car or lawn mower, the intake, compression, combustion, and exhaust steps occur in the same place (cylinder head) at different times as the piston goes up and down. In the turbine engine, however, these same four steps occur at the same time but in different places.
