An optical method for measuring exhaust gas pressure from an internal combustion engine at high speed

Abstract:

Measurement of exhaust gas pressure at high speed in an engine is important for engine efficiency, CFD analysis, and turbocharger matching. Currently used piezoresistive sensors are bulky, require cooling, and have limited lifetimes. A new sensor system uses an interferometric technique to measure pressure by measuring the size of an optical cavity, which varies with pressure due to movement of a diaphragm. This pressure measurement system has been used in gas turbine engines where the temper...
