Classification: CPC F  Y | IPC F

Claim 9:
10. A method for controlling a two-stroke engine operatively connected to a turbocharger, the turbocharger being in fluid communication with the engine to provide a boost pressure thereto, the method comprising:
determining a boost target pressure of the turbocharger;
determining an exhaust temperature representative of a temperature of exhaust gas being discharged by the engine;
determining a boost target pressure correction factor based at least in part on the exhaust temperature, the boost target pressure correction factor being determined based at least in part on:
the exhaust temperature, and
a throttle position of a throttle valve regulating air flow into the engine,

determining the boost target pressure correction factor comprises:
accessing a predetermined dataset, and
retrieving the boost target pressure correction factor from the predetermined dataset based on the throttle position and the exhaust temperature; and

controlling the turbocharger to increase the boost target pressure of the turbocharger in accordance with the boost target pressure correction factor to increase an actual power output of the engine.
