Generalised Procedure for Flame and Combustion Chamber Surface Determination in S I Engines 821223

A generalised computational procedure for the evaluation of the geometry of convex flame surface and combustion chamber interaction is presented. A range of combustion chamber geometries have been evaluated for flame surface area, volume, and wall wetted area under the assumption of spherical flame development. The study shows the advantage of bowl in piston geometries with central ignition. Incorporation of the geometric scheme into a Thermodynamic combustion model corroborates the findings of the geometric study.
