A fiber-optic sensor system, based on interferometric fiber-optic pressure sensor has been developed to measure cylinder pressure for closed-loop process control. The pressure-need sensors for improved for reciprocating in-cylinder engines is widely recognized. The ideal sensor would give accurate readings of combustion chamber gas pressure with high temporal resolution within each engine cycle. Engine control systems incorporating these sensors could reduce harmful emissions levels and improve fuel economy, as well as perform parametric monitoring for predicting emission levels. In the paper the interferometric fiber-optic pressure sensor was descripted. Measurements on a gasoline-fueled engine were reported.
