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: 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.

Abstract: Provided are a method and an ICE system, including an internal combustion engine including a first and a second set of cylinders. A first and a second EGR valve control flow of exhaust gas from the cylinders to an EGR conduit. A controller controls the closing of the second EGR valve, thereby preventing flow of exhaust gas from the second set of cylinders to the EGR conduit. The second EGR valve is upstream of a turbine. The controller is configured to activate a fuel injector for late post injection of fuel into the second set of cylinders when the second EGR valve is closed, so that at least a part of the fuel that exits the second set of cylinders is uncombusted. An exhaust gas aftertreatment system receives and treats exhaust gas which is not recirculated in the EGR conduit, and includes an oxidation catalyst for combustion.
