基于虚拟仪器自主开发的汽油发动机燃烧分析系统

Gasoline Engine Combustion Analysis System Based on LabVIEW

对发动机的燃烧过程以及排放状况有较深入的研究,需要相关燃烧分析系统的开发。通过自主开发的燃烧分析系统软件,实现数据釆集、数据处理、数据计算以及显示等功能,分析处理气缸指示功、最高压力等随曲轴转角变化的规律,能够为后期的发动机设计优化提供重要帮助。该测试系统对3433-06发动机不断测试与使用,发现其开发成本更低、操作界面友好、方便不断开发优化,最终结果证明该燃烧分析系统运行稳定可靠,具有较高的工程应用价值。

In order to have a depth research emissions , it is necessary to develop a excellent for the combustion process and the status of the engine combustion analysis system. The data collection, data processing, data computing and other display functions were realized by the selfdeveloped combustion analysis system software , and some relative analyses of cylinder dynamic combustion were done. At the same time, it is so important for designers have an optimization of engine if they use the P - Ф indicator diagrams, Pmax indicator diagrams, airfuel ratio （ξ） and fuel consumption variation data and so on. The test system for an internal engine combustion analysis through continuous testing and use, is feasible. No doubt, Better user interface and lower costs of this combustion system is pretty good for tester analysis the related data. Designers could facilitate the continuous development and utilization, so it has a certain value in engineering.
