Abstract
This paper describes a simple computer model developed for analysing the squish motion in the pentroof combustion chamber. The model is used to predict the effects of various design parameters such as the compression ratio, pentroof angles and compression plane margin on squish velocity. The results of the parametric study are presented together with the mathematical description of the model. A number of guidelines are also given for the design of pentroof chamber.
