Parametric modeling and optimization of the intake and exhaust phases of a hydrogen Wankel rotary engine using parallel computing optimization platform

•A parametric model of intake and exhaust phases of Wankel rotary engine is developed.•Optimized intake and exhaust phases increase the indicated mean effective pressure.•Multi-objective particle swarm optimization algorithm is enhanced by Sobol sequence.•Sensitivity of performance and emissions to intake and exhaust phases is evaluated.•A parallel computing optimization platform based on MOPSO is established.
