    delivery ratio over the entire engine speed range. That is, for the engine used, the optimum value of K was around 2.2. When Fia was larger or smaller than this value, the delivery ratio became smaller. From these figures it follows that to obtain a large delivery ratio for the engine over a wide speed range, it is unnecessary to vary Fia ...

Scavenging in Two-Stroke Engines - DieselNet

    https://dieselnet.com/tech/air_scavenge.php
    The main scavenging methods are cross scavenging, loop scavenging and uniflow scavenging. The gas exchange process in two-stroke engines can be characterized with a number of parameters including delivery ratio, scavenge ratio, scavenge efficiency, purity of charge and trapping efficiency.

Volumetric efficiency - Wikipedia

    https://en.wikipedia.org/wiki/Volumetric_efficiency
    Volumetric efficiency (VE) in internal combustion engine engineering is defined as the ratio of the mass density of the air-fuel mixture drawn into the cylinder at atmospheric pressure (during the intake stroke) to the mass density of the same volume of air in the intake manifold. The term is also used in other engineering contexts, such as hydraulic pumps and electronic components.

    air discharge period. Fig. 3 shows the calculated delivery ratio. The engine speed n , at which maximum delivery ratio 0 is produced, decreases with an increase in the ratio of the crankcase clearance volume to the piston displacement. However, the maximum value of the delivery ratio is scarcely affected by the clearance volume.
