基于Modelica的生物质燃气内燃机性能模拟研究
Simulation of internal combustion engine fueled by natural gas/liquefied petroleum gas-biogas blends with Modelica
摘要
Abstract
Since the physical and chemical characteristics of biogas, some problems such as slow combustion speed, uncompleted burned fuel and high exhaust temperature will occur in its applications in engine. The biogas engine model library was built with the object-oriented language Modelica, the performance of a four-stroke spark-ignition gas engine operating with natural gas/liquefied petroleum gas-biogas blends were investigated. Natural gas (33 ％, 67 ％ and 100％) and liquefied petroleum gas (5％, 10％ and 15％) were added to the biogas and were simulated as the fuel of SI engine. The effects of natural gas/liquefied petroleum gas-biogas blends on the performance of spark-ignition engine used for electricity production were numerical investigated, the results were validated through the experiments on a gasoline modified gas engine. The results suggest that: There is an improvement in brake thermal efficiency and brake powers with the addition of natural gas/liquefied petroleum gas in biogas. The feature of reusable and object-orien-ted of Modelica will enhance the modeling and simulation of biogas engine performance greatly not only in accuracy but simulation efficiency, this would be efficient for the design and the optimum work of the biogas fuelled engine.关键词
