Experimental Study on Exhaust and Scavenging Process Regarding Turbocharging of Two-Cycle Diesel Engine

Abstract

A series of experiments on the discharge and scavenging phenomena of two-cycle diesel engine of uniflow type was carried out by means of a test rig, which faithfully represents the phenomena in a fired engine, only using the compressed air separately charging and boosting the cylinder from different pressure sources. The experimental results show good agreement with those calculated and verify as a whole that the simple method of calculation proposed by the author may well be applicable to the practical purpose of evaluating the phenomena and the associated problems under design stage. At the same time, the results obtained with the test rig may be applied to presume the performance of the fired engine having the same exhaust and scavenging characteristics, though certain modifications are required according to the differences in temperature condition, etc.
