| Abstract: | Aiming at the problem about Electro Magnetic Compatibility（EMC） appeared in the common- rail pressure sensor applied in the diesel engines, this paper analyzes the mechanism that the pressure sensor is disturbed according to the three elements of electromagnetic interference. The filter in the circuit of the pressure sensor is ameliorated. Testing result shows that the pressure sensor can satisfy the requirement about the CS114 item in GJB151A-97. The improved methods can also be used in other pressure sensor＇s design. |
