Abstract
Method of controlling the injection of a fluid into an internal combustion engine, comprising a piston reciprocating in a cylinder between top and bottom dead center points, and a nozzle arranged in the cylinder. The method includes injecting a fluid with an initial injection pressure into the cylinder, the fluid being ignited, so that the pressure in the cylinder increases, thereby causing the piston to be displaced towards the top dead center point, and effecting at least one injection pause during injection. The injection, immediately after the injection pause, is effected so that the injection pressure has increased in an interval of more than 0 bar and up to 2000 bar relative to an injection pressure prevailing immediately prior to the injection pause, and the injection pause is effected for a duration corresponding to an angle of rotation of an engine crankshaft in the interval 1°-30°.
