Abstract:
Precise knowledge of cylinder pressure is needed for optimizing engine performance. To ensure reliability of measurements, pressure sensors need to be calibrated at conditions that correspond to actual use, i.e., at dynamic conditions and elevated temperatures. VTT has developed a dynamic pressure calibrator based on reference sensor principle to enable cost-effective dynamic calibrations up to 35 MPa at temperatures up to 200 °C. Moreover, a novel cylinder pressure sensor that can withstand the harsh conditions inside an engine was developed and the performance was validated in laboratory and inside a marine engine.
