The 2-cycle engine, which we have tested, has only a 100cc cylinder capacity and, according to the competition rules, is not allowed to be equipped with a gear shift. So the engine is required to have first of all, stable power performance from the lower speed revolution range to that of higher one. This requirement gives to the 2-cycle racing engine quite a different design from that of the ordinary 2-cycle engine which is equipped with gear shift and of which the performance shows a peak only within the particular revolution range. Our test has the following two purposes : First, in orer to find what ingredients they contain, we have analyzed the metal materials used for the racing engine designed under such conditions. And in so doing, we have tried to discover what metals can prevent the engine from over-heating in solving the current problem of power loss caused by over-heating. Secondly, we have investigated various conditions which have caused the engine to be over-heated with the improvement of performance. As for the metal test, we have tried various experiments such as microstructure observation as well as macro-structure, hardness test, chemical analysis and so on.
