An Analytical Method for Optimizing the Scavenging Process of Uniflow Two-Cycle Diesel Engines

A mathematical model of the scavenging process of uniflow two-cycle diesel engines is proposed. It assumes that certain general characteristics of a particular engine type are known. With a number of simplifying assumptions, the scavenging process and engine performance can then be analyzed by means of a digital computer. Experimental results are used to demonstrate the validity of the analysis. A number of scavenging system variables are investigated and a combination is proposed which should give optimum performance.
