1. A method for controlling an internal combustion engine comprising a cylinder, an air guide arranged to guide an air flow to the cylinder, an adjustable air flow restriction element arranged upstream of the cylinder to control the air flow guided through the air guide, an exhaust guide arranged to guide an exhaust flow from the cylinder, an adjustable exhaust flow restriction element arranged downstream of the cylinder to control the exhaust flow through the exhaust guide, and the method comprising the steps:
determining a value of at least one engine operation parameter, wherein the at least one engine operation parameter is at least one of the following:
an engine speed,
an engine load,
a coolant temperature, and
an ambient temperature,
determining a target value of an exhaust performance parameter depending on the determined engine operation parameter value, wherein the exhaust performance parameter is an exhaust temperature and an exhaust manifold pressure;
determining a current exhaust performance parameter value, wherein the current exhaust performance parameter value is a current exhaust temperature value and the current exhaust manifold pressure value;
depending on the determined target exhaust performance parameter value,
controlling the air flow through the air guide depending on a deviation of the determined current exhaust temperature value from the determined target exhaust temperature value and
controlling the exhaust flow through the exhaust guide depending on a deviation of the determined current exhaust manifold pressure value from the determined target exhaust manifold pressure value.
