What allows air to be introduced into the cylinder of a two-stroke diesel engine?

Two-stroke diesels admit air through openings in the cylinder wall called intake ports. As the piston moves downward, it uncovers these ports, and air from the intake system flows into the cylinder to fill the swept volume. This port timing provides the necessary air without a separate intake valve. The intake manifold simply delivers air to the port area, while the piston rings seal and do not control air entry.
