The present disclosure relates to an exhaust system for an internal combustion engine. The exhaust system comprises an exhaust conduit adapted to fluidly connect the internal combustion engine to a turbine of a turbo and a valve comprising a valve flap located in the exhaust conduit in a position between the internal combustion engine and the turbine. The valve flap is pivotally connected to at least a portion of the exhaust conduit. The exhaust system further comprises an actuator adapted to impart a load on at least a portion of the valve to thereby control a pivotal position of the valve flap in the exhaust conduit to thereby control a gas flow via the exhaust conduit and an actuator load sensor adapted to detect load information indicative of a magnitude of the load that the actuator currently imparts on at least the portion of the valve.

Exhaust system for an internal combustion engine

The present disclosure relates to an internal combustion engine (ICE) system comprising: an internal combustion engine; a turbocharger arrangement, the turbocharger arrangement having a turbine arranged in an exhaust gas conduit, the exhaust gas conduit extending between the internal combustion engine and the turbine, and further a compressor disposed in an inlet manifold, the inlet manifold extending between the compressor and the internal combustion engine; a controllable backpressure valve being located in the exhaust gas conduit, the controllable backpressure valve being configured to control the pressure within the exhaust gas conduit; a pressure sensor disposed in the exhaust gas conduit, and further in-between the controllable backpressure valve and the turbine, the pressure sensor being configured to measure an exhaust gas pressure downstream the controllable backpressure valve; a speed sensor configured to measure a compressor speed; and a control system for determining an operational status of the pressure sensor.
