Description

Analysis of valve motion would reduce a great deal of experimental work preceding the final decision of valve gear design. A lot of attempts for such analysis have not been quite successful with their poor experimental data to be compared with the calculated results, which in due course mada authors take great care for such measurements at the beginning of the study. In this report authors introduced their methods of measurements for such use and discussed a single mass system (serial system composed of cam-equivalent push rod-equivalent valve mass-valve spring) for the description of valve motion. New definition of single mass system has enabled authors to give elegant explanation of various dynamic behaviors which characterize actual systems. This new equivalent system was applied to the calculation of valve motions, which were closely compared with the experimental results mentioned above.
