다국어 초록 (Multilingual Abstract)

The present paper reports primarily of an experimental investigation of the effects of the pressure ratio between scavenging pressure and back pressure and engine speed on the scavenging processes of a uniflow model cylinder similar to the G.M. 7-21.
The pressure ratio was changed from 1.151 to 1.355, and the engine speeds were 100, 120 and 150 revolutions per minute respectively.
From the results of this investigation, it has been concluded that
(1) dimensionless numbers to correlate the experimental results are eight in all, but still one more including the effect of the valve and port timing is seemed to be necessary and
(2) no effect of the engine speed on scavenging processes is detectable.
