Combustion Chamber Design Effect on The Rotary Engine Performance - A Review

Comparatively, this review is meant to focus on possible developments studies of the rotary engine design. The controversial engine produces a direct rotational motion. Felix Wankel derived the triangular rotor shape from complex geometry of the Reuleaux triangle. The Wankel engine simulation and prediction of its performance is still limited. The current work reviews rotary engine’s flow field inside the combustion chamber with different commercial software used. It studies different parameters effect on the performance of the engine, such as the effect of the recess sizes and the shape-factor. It is found that the engine chambers design is one of the aspects of improvement opportunities.
