[0010] Such as figure 1 As shown, a fuel injection sensor is installed on the fuel collector 1 of the present invention, where the fuel injection sensor is a piezoelectric fuel injection sensor, and the piezoelectric fuel injection sensor includes an induction column 2 made of insulating material, and an induction column 2 Insert it into the socket provided at the bottom of the oil collector. A sealing ring 3 is installed between the induction column 2 and the socket. The bottom end of the induction column 2 is successively installed with the upper conductive sheet 5, the piezoelectric crystal 6, the lower conductive sheet 7 and The pressure plate 8, the above-mentioned components are encapsulated in the sensor housing 4, the upper conductive sheet 5 is in contact with the pressure plate 8 through high-impedance insulated wires, the lower conductive sheet 7 and the pressure plate 8, and the wires are led out from the notches 9 on the metal sensor housing 4 respectively. When the ...
