A computer simulation code is developed to predict the engine performance of a spark-ignition engine, taking the occurrence of knocking into consideration. In this simulation, time-evolution is solved based on mass and heat flow during the cycle. Knocking is described by using the Livengood-Wu function giving ignition delay data estimated by Nishiwaki and the coworkers. Results of prediction show reasonable degree of reproduction of actual tendency of in-cylinder processes over a range of engine running. The developed code will be a useful tool for improving the engine performance.
