Presentation Transcript

  1. ICE combustion analysis

  2. Determining the working process • Measuring the cylinder pressure in the function of the crank shaft revolution (crank angle)

  3. Averaging

  4. Pressure against cylinder volume

  5. Piezoelectric pressure measuring • Charge (electricity) generated due to mechanical force • Very fast response • Wide temperature range up to 400 °C (1300°C) • Static pressure can not be measured (just dynamic or quasi static)

  6. Longitudinal effect • Qx = d11 · Fx · n • Simple, robust

  7. Transversal effect • Qx = –d11 · Fy · b/a • Highsensitivitycan be achieved

  8. Shear effect • Qy = –2 · d11 · Fx · n • Highsensitivitycan be achieved

  9. Model of piezoelectric sensor • q: Charge generator • Ct : sensor capacitance • Cc : cable capacitance • Ri : sensor and cable resistance

  10. Model of measuring system
