现代柴油机性能预测

现代柴油机设计时通过CAE分析可以对性能进行预测,对新研制的柴油机的概念设计,采用先进的设计分析技术进行整机性能模拟计算,预测了发动机的性能指标,确定了气门定时、增压器匹配方案和进、排气系统几何尺寸.通过与样机试验结果的对比,验证了前期整机性能计算的正确性.

Concept Design of Modern Diesel Engine-performance Prediction

CAE could be used for analyzing and making performance prediction of the modern diesel engine.For concept design of the new developed engine,performance simulation calculation of the whole engine is done with the advanced design analyzing technology,through which it predicts the performance targets of the engine and determines the valve timing,matching variants of the turbocharger and geometric dimensions of intake&exhaust system.To compare with the test data from the prototype engine,it verifies the previo...
