Abstract
The problem of scavenging in any two-stroke engine requires highly sophisticated research methods. To obtain satisfactory results it is necessary to investigate the phenomenon under all its aspects, often resorting simultaneously to different qualitative and quantitative procedures with different degrees of approximation.
The paper describes methods developed by FIAT Gas Dynamics Laboratories and presents, in particular, the fundamental characteristics of a dynamic test bench designed to provide a highly severe simulation of the actual process and to yield considerable technical-economical advantages. This test bench, though devised and used mainly for medium and large engines, is the clearest example of the possibilities derived from grouping all these research programs at a center specialized in the field of fluid dynamics.
