摘　　要：以产量大、应用广泛的单缸柴油机为对象,应用计算机模拟计算方法并配合以先进的整机性能测试和数据处理手段,为内燃机与各种工作机械的合理匹配以及综合性能评价、诊断、预测和参数优化提供了一种切实可行的有效方法。着重研究进气管系统,但所用方法也适用于不同气门直径、升程,配气相位和凸轮型线等的优化匹配。本文提出的用弹性稳压腔取代传统的长管增压所采用的大尺寸稳压箱的设计方案,实用效果得到实验验证。A method of computer simulation with performance measurement to assess,diagnose and predict the comprehensive performance and optimize the parameters for the reasonable matching of one-cylinder diesel engines and working machines is presented.Investigating emphatically in inlet systems,the method is also available to optimize other parameters of valve diameter,cam lift,intake and exhaust phases and cam profile etc. An elastic chamber,besides,is designed and its working principle is proved by measured results.A dig-sized constant pressure box can be Jeplaced by this chamber.Therefore,the size of inlet system is to be minimized.
