    摘要：柴油机示功图含有与柴油机性能相关的丰富信息,它综合反映了柴油机热力转换过程和工作状态,结合其结构参数可以获得各缸平均指示压力、指示功和最高爆发压力等重要性能指标。虚拟仪器具有效率高,性能好,控制灵活,精度高等特点。为此以可视化的虚拟仪器系统Labview为开发平台,把传统仪器的所有功能模块集成在一台计算机中,设计了基于虚拟仪器的柴油机示功图采集系统,为柴油机性能监测与故障诊断提供了有效的技术手段。 

    Abstract：The indicating diagram of a diesel engine shows lots of information about the diesel engine performance,while presenting thermodynamic cycle and work state of the diesel engine and important performance parameters of mean effective pressure,indicated power and Peak Pressure.Because a virtual instrumentation may features good efficiency and performance,easy control and high precision,the paper design a collecting system of the indicating power base on the virtual instrumentation,where all kinds o...
