本文阐述增压器与柴油机匹配初步设计的一种估算方法。在详细计算中常常要作大量假设和各种参数选择,在实际试验中也要作许多方案比较。这种估算方法可在电算和试验前选定各种参数的变化范围,可使配机设计少走弯路。本文用线图表达一些基本关系式,以便看出各种参数对结果的影响。线图中也列入四冲程机16V240型、二冲程机18V 390型和9I 900型柴油机的配机实例。由于它们的数据是实际值,又都落入线图估算范围,因此这些线图是切实可用的。
This article describes an estimation method for the preliminary design of a turbocharger and a diesel engine. In the detailed calculation often make a large number of assumptions and a variety of parameter selection, in the actual test also have to make many programs to compare. This method can be estimated in the calculation and test before the selection of a variety of parameters of the range, can make the machine design less detours. This article uses line diagrams to express some of the basic relationships in order to see the effect of various parameters on the result. Line diagram also included in the four-stroke 16V240-type, two-stroke 18V 390-type and 9I 900 diesel engine with machine examples. Since their data are actual values and fall within the estimated range of the line graph, these line graphs are in fact available.
