摘要
本文讨论了适用于优化计算的柴油机工作过程数学模型所应满足的一些要求,认为至少要具有真实性、包容性和可实现性这3个基本原则。以此为基础。对于考虑排放限制条件的优化问题,通过分析柴油机中工质所经历的各热力状态,从热力学的观点。将整个系统划分为由若干子系统组成的串并联系统。进而由守恒方程、子系统间的相容条件及状态方程,建立一个准维柴油机工作过程数学模型。以一中速大功率柴油机为例,对该模型进行了检验。
A Q-D model of D. I. diesel engine performance was presented with the object of computer simulation optimization. To set up the model, some conditions required were discussed. They are, at least, reality, containment ability and realizability. By means of thermodynamic analysis, diesel engine thermocycle system was restricted to a system with several sub-systems connected in parallel-series, which is the physical model. The comparision between results calculated by the model and the experiments shows that the model is reasonable and satisfactory.
