摘　　要：摘要本文以某大功率柴油机为计算实例,对适合于内燃机工作过程性能优化的三种计算方法进行了较为详细的理论探讨与研究,得出如下结论:①序列线性优化法适合于内燃机工作过程性能优化的粗略计算;②序列无约速极小化法适合于变量较少的内燃机工作过程性能优化的精细计算;③正交网格优化法的适应性较强,但计算时间较长,较适合于多变量内燃机工作过程性能优化的精细计算.Taking a high-output diesel engine as example, three calculation methods for optimization of diesel engine in-cylinder processes were investigated theoretically in some detail. It was found that (1)S.L.P. is suited for rough estimation of diesel in-cylinder processes optimization; (2)S.U.M.T. is suited for elaborate optimization calculation of diesel in-cylinder processes with few variables; (3)O.N.O.M. has a wide adaptability, but needs much computer-time, and is suited for elaborate optimization calculation of in-cylinder processes with many variables.
