Abstract

The invention relates to a method to control an internal combustion engine. The internal combustion engine comprises a cylinder, an air guide pipe arranged to guide an airflow to the cylinder, an exhaust guide pipe 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 are controlled depending on the determined target exhaust performance parameter value.

Description

technical field [0001] The invention relates to a method for controlling an internal combustion engine, a computer program, a computer readable medium, a control unit, an internal combustion engine and a vehicle. [0002] The invention can be applied to heavy vehicles such as trucks, buses and construction equipment. Although the invention will be described in relation to a heavy vehicle, the invention is not limited to this particular vehicle, but may also be used in other vehicles, such as cars. Background technique [0003] WO 2015 / 108472 A1 provides a method and a system arranged for controlling at least one temperature of an exhaust gas treatment system in a vehicle. The system comprises a first determining unit arranged for determining at least one temperature of the exhaust gas treatment system and a second determining unit arranged for determining the temperature of the brakes used in the vehicle order of priority. The order of priority is determined based on the ...
