Paper Powerplants Promote Performance Progress 750016
Development and application of computer analysis to the flow system of the internal combustion engine is discussed. Particular attention is directed to the crankcase-scavenged, two-stroke-cycle, spark ignition engine, with the objective of optimizing the relationships between its complex transient flow processes and its basic mechanical simplicity. The aspects of specific output and fuel consumption, as well as those of the emission of noise and other obnoxious constituents of the exhaust, are considered. A systematic procedure is presented for determining the most practical port and duct dimensions for a new engine application.
