Abstract: The present invention relates to method for controlling a compression-ignition internal combustion engine, said internal combustion engine having at least one combustion chamber, wherein intake of air to said combustion chamber is controlled using an intake valve, and wherein evacuation of said combustion chamber is controlled using an exhaust valve. The method includes: controlling opening of said intake valve and closing of said exhaust valve in dependence of the position of a reciprocating member in said combustion chamber, wherein opening of said intake valve and closing of said exhaust valve, respectively, in relation to the position of said reciprocating member is individually controllable, and wherein, in one mode of operation, opening of said intake valve and closing of said exhaust valve, respectively, are controlled such that both valves are simultaneously open during a period of variable length.

The method comprises: controlling opening of said intake valve and closing of said exhaust valve in dependence of the position of a reciprocating member in said combustion chamber, wherein opening of said intake valve and closing of said exhaust valve, respectively, in relation to the position of said reciprocating member is individually controllable, and controlling opening and closing in relation to the position of said reciprocating member on the basis of a first control parameter, wherein said opening and closing of said intake valve and exhaust valve, respectively, are controlled such that an actual value of said control parameter is adjusted towards a desired value.
