Abstract: The detection of engine fuel oil pressure is of practical significance to ensure the normal operation of automobiles. Through the portable engine oil pressure tube detection device designed in this paper, non-destructive oil pressure detection can be realized by non-direct contact with fuel. The device realizes the data acquisition, analog conversion and real-time display of the pressure in the pipe by means of mechanical conversion mechanism, pressure sensor, data acquisition and data display. The correctness of the design idea is verified by the practical measurement and application of the portable out-of-pipe testing device.
