用新研制的卡持式传感器及其测试系统,在高压油泵试验台上做了调整喷射系统喷油器循环喷油量、喷油开启压力和高压油泵转速的试验,测得了各种试验条件下的压力波、计算了压力波的特征值.在此基础上,研究了各调整参数对测量的电压波形及其特征参数的影响程度和规律;证明了外卡式传感器测量的电压波能真实地反映高压油管内的压力波动,可用于喷射系统各角度的动态测量. With the newly developed card-holding sensor and its testing system, high-pressure pump test bench to do the injection system to adjust the fuel injection cycle injector, fuel injection pressure and high-pressure pump speed test, measured a variety of test conditions The characteristic value of the pressure wave was calculated.On the basis of this, the influence degree and rule of each adjustment parameter on the measured voltage waveform and its characteristic parameters were studied. It was proved that the voltage wave measured by the outer card sensor could be truly Reflect the pressure fluctuations within the high-pressure tubing can be used for the dynamic measurement of the injection system at all angles.
