Compared to multi-cylinder engines with the same displacement,
a single-cylinder engine works on a set of machine parts only, so
the inertial force of the moving parts cannot be offset, resulting
in high vibration. This is especially true as speed rises. In addition,
the moving parts of a single-cylinder engine are relatively larger,
which is adverse to speed increase, and is especially true as
displacement rises. Therefore, the larger the displacement of a
single-cylinder engine is, the lower power per liter will be, but the
stronger pulsing will be.
Since single-cylinder engines are simple in structure, they are
characterized by light weight and small size as compared to
multi-cylinder engines with the same displacement, so a single-
cylinder engine helps reduce overall weight and improve overall
operating flexibility.
