The effects on thermodynamical cycle due to cylinder gas leakage were calculated, and compared with experimental results. This paper involves Otto cycle only. On gas leakage cycle, general solution was proposed for evaluating end-pressure and residual gas quantity of compression or expansion stroke. On the calculation of cycle, regarding gas leakage as heat loss, gas quantity during a cycle was assumed constant, and also it was assumed that calorific value of combustion gas decreases in proportion to gas leakage during compression stroke. In conclusion difference between leakage cycle and perfect cycle changes for the more according to the increase of leakage area and compression ratio, the decrease of number of revolutions and stroke volume. The results of calculation coincide approximately with experimental results.
