This paper represents results of a theoretical work devoted to diffusion and removal of ring crevice HC’s. The model consists of three major sub models: a model for prediction of time-varying composition of combustion gases, a model for the ring crevice HC’s during late expansion and exhaust stroke and the last one for a simple phenomenological approach to calculate temperature variation. Flow field and HC concentrations are determined by solution of governing equations. Oil film HC’s and post flame oxidation are excluded, as for the last, solution procedure enhances the period after which in cylinder oxidation ceases. A 60 × 60 variable mesh flow field is adapted for finite volume solution procedure. Results are presented at the extended limited counterparts allowed, due to the lack of common parameters adapted in different studies amongst plenty of them.
