Classification: CPC F  Y | IPC F

Claim 13:
14. 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, the boost target pressure being determined based at least in part on:
a throttle position of a throttle valve regulating air flow into the engine, and
a rotational speed of the engine,

determining the boost target pressure of the turbocharger comprising:
accessing a predetermined dataset, and
retrieving the boost target pressure of the turbocharger from the predefined dataset based on the throttle position of the throttle valve and the rotational speed of the engine;

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; 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.
