0 前言 涡轮增压器与新设计的发动机或与需提高功效的发动机的匹配工程可能是费时间的艰苦过程。如果所研究的是大型工业涡轮增压柴油机,其匹配工程是昂贵的。为此以分析法计算不同方案的综合性能,据此选用相应的涡轮增压器开始实机试验直至得到认定的最佳匹配方案。这样可以缩短新机型的开发时间,因而减少经费。 模拟计算(以下简称模型)法用途甚广。新发动机设计阶段一般先以合适的模型预测不同增压压力下的性能参数、计算总的
0 Introduction Matching a turbocharger to a newly designed engine or to an engine with increased efficiency can be a time-consuming and painstaking process. If you are looking at a large industrial turbocharged diesel engine, its matching works are expensive. To this end the analytical method to calculate the overall performance of different programs, accordingly select the appropriate turbocharger to start real machine test until you get the best match program. This will shorten the development time of new models, thus reducing funding. Simulation calculation (hereinafter referred to as the model) method is very versatile. The new engine design phase generally first with a suitable model to predict the performance under different supercharging pressure parameters to calculate the total
