| 摘 要： | 介绍了两种车载测量油耗的新方法。电喷法通过高频采样系统测量电喷脉宽,计算得到油耗;空燃比法测量记录进气流量计电压及空燃比等信号,计算得出油耗。两种新方法与汽车尾气CVS取样测量的对比试验表明:两种新方法具有优良的测量精度和稳定性。

| Abstract: | Two new ways of measuring the fuel consumption by on-board system are presented: electronic fuel injection(EFI) method and Air/fuel ratio(AFR) method.The EFI method is based on the measurement of the pulse width of EFI by high frequency sampling system,while the AFR method measures the signals like voltage in intake-air flow meter and the AFR etc.The two new ways are compared with exhaust gas CVS sampling method.The results show that the two new methods have good measuring accuracy and stability. |
