FIELD: measuring equipment.
SUBSTANCE: invention relates to a system and methods of operating a laser pressure sensor for accurate assessment of pressure in an inlet manifold or in an engine exhaust manifold. Laser circuit is connected to pressure-sensitive membrane, which is mounted in engine manifold. Collector pressure is determined on the basis of deflection of the membrane estimated by time between emission of laser pulse into membrane and detection of pulse reflected from membrane. Then, engine operation is adjusted in accordance with estimated collector pressure.
EFFECT: invention discloses a system and methods of operating a laser pressure sensor.
