複動Diesel機關Piston棒損傷の一例に就て

抄録

Double acting Diesel engines have rapidly increased in number and output in late years in this country, owing to the idea of applying Diesel engines as only means of economical power production of large units for marine propulsion. Few reports of theoretical or experimental analysis about the piston rod of the double acting Diesel engine have been published, which would be of great value for designers and engineers. The author reports the analysis of the causes of the damage on the piston rod of the main engine of the motor ship “Kohwa Maru”, the first double acting two cycle Diesel engine adopted for ship propulsion in this country.
