Patent ID: 6935303

Claim:
Method of controlling the injection of fluid into an internal combustion engine, comprising a piston reciprocating in a cylinder between top and bottom dead center points, and an injection nozzle arranged in the cylinder, said method comprising the steps of effecting a first injection of fluid with an initial injection pressure into the cylinder when the piston is near top dead center, said fluid being ignited so that the pressure in the cylinder increases, thus causing the piston to be displaced towards the bottom dead center in the cylinder, and effecting at least one injection pause during the injection of fluid, characterized in that a post injection of fluid, immediately after the injection pause, is carried out, when the piston is moving towards bottom dead center, so that the initial pressure is increased in an interval of more than 200 bar and up to 2000 bar relative to an injection pressure prevailing immediately prior to the injection pause and that the injection pause is effected for a duration corresponding to an angle of rotation of a crankshaft arranged in an engine, in the interval of more than 3 ° and up to 30 °.
