Measuring the clamp-on pressure of high pressure fuel pipe is a shortcut for obtaining injection parameters and fault diagnosis of the fuel injection pumps [1,. Based on the analysis of the fuel injection process of fuel injection pump, analyzed the differences of practical injection process and geometric injection process, and obtained the theory waveform feature points of diesel engine high pressure pipe fuel injection process. In order to obtain the clamp-on pressure waveform which feature points consistent with the theoretical waveform, designed the hardware filter based on MAX293. Considering the clamp-on pressure signal sometimes must also meet the requirements of no delay, designed frequency domain filter. Two filtering methods have reached the expected results.
