Up to this day, known piston crank mechanisms used in various reciprocating internal combustion engines are inevitably accompanied with vibration, as the forces and moment caused by the inertia of the reciprocating mass are not balanced. Perfectly balanced rotation-reciprocation mechanisms can obviate or mitigate such disadvantages. This report relates to a gasoline engine utilizing an eccentric geared device of crank-shaft rotary motion system as the mechanism of motive power. Theories and experiments of this engine are described: that is - vibration tests, various performance test 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 on the improvement of the performances of this engine hereafter.
