基于正交试验方法的某六缸发动机性能优化
Performance Optimization of a Six-cylinder Diesel Engine Based on Orthogonal Experimental Design
摘要
Abstract
Based on the AVL BOOST software, a six-cylinder engine model was established, the single effect of intake timing, exhaust timing and fuel injection advance angle on the engine performance was analyzed, then the graphs of the three factors'influence were drawn;the order of the factors significant-ly affecting the engine and the best combination of intake and exhaust timing and fuel injection advance angle were found by the orthogonal experiment method to optimize the engine performance. Finally, the fuel economy was point-estimated and verified. Through simulation analysis and optimization, the re-sults show the engine's economy is increased by 3.89%, the power performance is increased by 3.72%.关键词
