内燃机试验数据处理系统开发

Development of the test data processing system of internal combustion engine

为了评价内燃机在不同工况下运行的动力和经济性能,必须研究内燃机特性。文章介绍了内燃机试验数据处理系统,通过数据文件采集数据,由编制的软件根据相应公式计算内燃机的特性参数,采用拟合方法绘制内燃机特性曲线。实际应用表明,该系统可以方便、快速且准确地处理内燃机试验数据,并清晰地绘制特性曲线。

In order to study the characteristics of the internal combustion(IC) engine and evaluate the power and economic performance of the engine operating at different working conditions,the test data processing system of the IC engine is developed. The system collects data by the data file, calculates the characteristic parameters of the IC engine by the software compiled according to corresponding formulae, and draws the characteristic curves by using the curve fitting method. The practical application shows that the test data of the IC engine can be processed conveniently, quickly and exactly and the characteristic curves can be drawn clearly by using the presented system.
