Method for controlling an internal combustion engine

A method for controlling an internal combustion engine comprising at least one first cylinder and at least one second cylinder with respective reciprocating pistons, first and second intake guides arranged to guide air from a fresh air intake arrangement to the first and second cylinders, respectively, an intake valve arrangement being arranged to control the provision of air to the second cylinder via the second intake guide a fuel system arranged to inject fuel into the first and second cylinders, a first exhaust guide and a second exhaust guide arranged to guide gases from the first and second cylinders, respectively, towards an exhaust after treatment system, and a recirculation guide extending from the first exhaust guide to the second intake guide the method comprising

• allowing air from the fresh air intake arrangement to be received in the first cylinder,
• allowing gases in the form of the air received in the first cylinder or gases including at least a portion of the air received in the first cylinder to be expelled from the first cylinder,
• controlling an exhaust valve located in the first exhaust guide so as to reduce or inhibit the transport of gases from the first cylinder to the exhaust after treatment system and to guide to the second cylinder gases expelled from the first cylinder, and
• simultaneously controlling the fuel system so as to inject fuel into the second cylinder, so as to provide repetitive combustions with air in the gases guided to the second cylinder, and controlling the intake valve arrangement for throttling or inhibiting the supply to the second cylinder of air from the fresh air intake arrangement,
• characterized by comprising determining the temperature of gases expelled from the second cylinder, wherein the control of the intake valve arrangement is made in dependence on the determined temperature of the gases expelled from the second cylinder.
