涡轮增压器热力学模型与柴油机动态仿真
Thermodynamic Model of Turbocharger and Dynamic Simulation of Diesel Engine
摘要
Abstract
A dynamic model of centrifugal compressor was established based on the law of thermodynamic.The model could use only the basic structural parameters of the compressor without using the experimental data map.The compressor and turbine models consisting a turbocharger dynamic model were used in a joint matching simulation with the diesel engine model.Results show that the model enlarges the working range of compressor model and effectively improves the dynamic performance of diesel model especially at lower revolution and lower load.The model has fast calculation speed and excellent real time performance, which can be used in engine performance optimization, control system development, etc.关键词
