Abstract: The invention relates to a method to control an internal combustion engine. The internal combustion engine comprises a cylinder, an air guide arranged to guide an airflow to the cylinder, an exhaust guide arranged to guide an exhaust flow from the cylinder. The method comprises the step to determine a value of at least one engine operation parameter. Further, the method comprises the step to determine a target value of an exhaust performance parameter depending on the determined engine operation parameter value. Lastly, the air flow through the air guide and the exhaust flow through the exhaust guide is controlled depending on the determined target exhaust performance parameter value.

Abstract: An internal combustion engine is provided including a cylinder including a piston connected to a rotatable crankshaft, an exhaust guide being arranged to guide a gas flow from the cylinder, an adjustable flow restriction element arranged to restrict the flow through the exhaust guide, an exhaust valve arranged to control a communication between the cylinder and the exhaust guide, and an exhaust valve actuation assembly for actuating the exhaust valve so as to perform in each of a plurality of cycles of the cylinder an exhaust valve actuation sequence, wherein the exhaust valve actuation assembly is adapted to control the commencement of the exhaust valve actuation sequence to occur selectively at any crankshaft angle within a non-zero crankshaft angle interval.

Abstract: The invention relates to a method to control an internal combustion engine. The internal combustion engine comprises a cylinder, an exhaust guide arranged to guide an exhaust flow from the cylinder through a turbine, and a bypass guide arranged to bypass a bypass flow from the cylinder past the turbine. The method comprises the step to determine a value of at least one engine operation parameter. The method is characterized by the step to determine a target value of an exhaust performance parameter depending on the determined engine operation parameter value. Further, the method comprises, depending on the determined target exhaust performance parameter value, the step to control the exhaust flow through the exhaust guide and the step to control the bypass flow through the bypass guide.
