Method and system for controlling an internal combustion engine

(canceled)

A computer program product stored on a non-transitory computer-readable medium, said computer program product 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, said computer program product comprising computer instructions to cause one or more electronic control units or computers to perform the following operations:

• 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, so that intake air passes through the combustion chamber and simultaneously mixes with and evacuates exhaust residuals.

A system 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 system comprising:

• control means adapted to control 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 adapted to be individually controllable, and
• wherein, in one mode of operation, opening of said intake valve and closing of said exhaust valve, respectively, are adapted to be controlled such that both valves are simultaneously open during a period of variable length, so that intake air passes through the combustion chamber and simultaneously mixes with and evacuates exhaust residuals.

A vehicle comprising a system 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 system comprising:

• control means adapted to control 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 adapted to be individually controllable, and
• wherein, in one mode of operation, opening of said intake valve and closing of said exhaust valve, respectively, are adapted to be controlled such that both valves are simultaneously open during a period of variable length, so that intake air passes through the combustion chamber and simultaneously mixes with and evacuates exhaust residuals.
