The invention provides a method of controlling an internal combustion engine (1) in a vehicle comprising a cylinder (301, 302), a fuel system (330) for supplying fuel to the cylinder, an air guide (901) arranged to guide an air flow to the cylinder (301, 302), and an exhaust guide (501, 502) arranged to guide a gas flow from the cylinder (301, 302), the method comprising - controlling the engine to provide a braking torque, the control comprising, - terminating (S1) the supply of fuel to the cylinder (301, 302), - restricting (S4) the flow through the exhaust guide (501, 502), and - restricting (S6) the flow through the air guide (901), - wherein the control of the engine to provide a braking torque also comprises - determining (S5) a value of a rotational speed of a turbocharger (4) of the engine, and - adjusting (S6), in dependence on the determined turbocharger rotational speed value, the restriction of the flow through the air guide (901), and / or the restriction of the flow through the exhaust guide (501, 502).

A two-stroke engine (4) has a throttle motor (22) for driving a throttle valve (20), a fuel injection device (430) disposed in an intake system (18) including a crank chamber (420), and a control unit (24) controlling the throttle motor (22) and the fuel injection device. The two-stroke engine (4) is designed to achieve an engine rotation speed of 4,500 rpm to 7,000 rpm when the throttle valve (20) is fully open. The two-stroke engine (4) is operated with the throttle full open by the control unit (24), and a battery (8) is charged with electric power generated by a generator (6) using the two-stroke engine.
