Uniflow engine

A uniflow engine is a piston engine where gas flow through the cylinder proceeds in a single unidirectional flow, without reversals between strokes. This gives thermodynamic advantages as each group of ports can stabilise at an equilibrium temperature, rather than being alternately heated and cooled. For internal combustion engines, scavenging is also improved by this consistent flow direction.
