Performance enhancement of internal combustion engines is basically achieved through process type, fuel use, injection mode and, combustion chamber geometry modification. Extensive studies are being undertaken to optimize the performance of compression ignition engines by combustion chamber geometry modification, however, this is largely executed with experiments. Numerical results on the effect of piston crown geometry as a means of combustion chamber modification on the performance characteristics of a compression ignition engine are presented in this short paper. The impact of in-cylinder fluid flow velocity was used to evaluate the performance of the engine. The in-cylinder motion of the fluid was positively impacted using the conical, hemispherical and dual hemisphere indented piston crowns, which is in agreement with previous experimental studies.
