VIBRATIONLESS RECIPROCATING ENGINE (TRIAL MANUFACTURE AND EXPERIMENTS OF A SMALL TWO-CYCLE VIBRATIONLESS RECIPROCATING ENGINE).

This report relates to a gasoline engine utilizing an eccentric geared device of crankshaft rotary motion system as the mechanism of motive power. Theories and experiments of this engine are described: that is - vibration tests, various performance tests of this engine which is designed by the authors and manufactured on trial, are carried out. Moreover, results of their numerical computations on the equivalent moment of inertia and load on each portion are shown. As a result, it is proved that the inertia force and moment are perfectly balanced in this engine and that their vibrations are very small in comparison with those of the conventional reciprocating engines. However, it is important to study the improvement of the performances of this engine hereafter.
