Abstract:
A four-stroke internal combustion engine is disclosed comprising an exhaust valve control arrangement with an exhaust valve phase-shifting device configured to phase-shift control of the at least one exhaust valve to a state where the at least one exhaust valve is controlled in such a way that it is opened during the expansion stroke of the engine and closed during the exhaust stroke of the engine, in order to achieve engine-braking via compression in the cylinders during the exhaust stroke. An inlet valve control arrangement comprises an inlet valve phase-shifting device configured to regulate the amount of air pumped through the engine during the engine braking by regulating the phase-shift of the at least one inlet valve. The present disclosure also relates to a vehicle comprising an engine and method of controlling an engine, a computer program and a computer program for performing a method of controlling an engine.

Claim (Index 15):
A method of controlling a four-stroke internal combustion engine, wherein the engine comprises at least one cylinder; a piston arranged in each cylinder; an inlet system; a crankshaft; at least one inlet valve arranged in each cylinder, which inlet valve is connected with the inlet system; an inlet valve control arrangement configured to control each inlet valve on the basis of a rotational position of the crankshaft; at least one exhaust valve arranged in each cylinder, which exhaust valve is connected with an exhaust outlet of the engine; an exhaust valve control arrangement configured to control each exhaust valve on the basis of the rotational position of the crankshaft, wherein the exhaust valve control arrangement comprises an exhaust valve phase-shifting device, wherein the inlet valve control arrangement comprises an inlet valve phase-shifting device, and wherein the method comprises:\n phase-shifting control of the at least one exhaust valve, using the exhaust valve phase-shifting device, to a state where the at least one exhaust valve is controlled in such a way that it is opened during the expansion stroke of the engine and closed during the exhaust stroke of the engine, in order to achieve engine-braking via compression in the cylinders during the exhaust stroke; and regulating the amount of air pumped through the engine during the engine braking, by regulating the phase-shift of the at least one inlet valve, using the inlet valve phase-shifting device.
