PSO; MOPSO; optimization; and engine control inputs


In order to cope with energy crisis, and emission pollution, an engine with lower pollution burden is appreciated. In this research, diesel engine optimization objectives are formulized on the basis of experiment data. The reduction of brake specific fuel consumption (BSFC), exhaust gas emission, and soot using particle swarm optimization (PSO) and multi-objective particle swarm optimization (MOPSO) is proposed. Optimal results of PSO are obtained and validated by engine test bench. In this paper, MOPSO with three optimization objectives are presented and simulated, these optimal results of MOPSO would also be tested in experiment in the future.
