摘要： The invention relates to a method of controlling the injection of a fluid into an internal combustion engine (1), comprising a piston (3) reciprocating in a cylinder (2) between top and bottom dead center points, and a nozzle (4) arranged in the cylinder (2). The method comprises the steps of injecting a fluid with an initial injection pressure (NOP I ) into the cylinder (2), said fluid being ignited, so that the pressure in the cylinder (2) increases, thereby causing the piston (3) to be displaced towards the bottom dead center point in the cylinder (2), and that a least one injection pause (U I ) is effected during the injection of the fluid. The injection of the fluid, immediately after the injection pause (U I ), is effected so that the injection pressure (NOP I+1 )has increased in an interval of more than 0 bar and up to 2000 bar relative to an injection pressure (NCP I ) prevailing immediately prior to the injection pause (U I ), and that the injection pause (U I ) is effected for a duration corresponding to an angle of rotation (α) of an engine crankshaft (10) in the interval 1° -30°, preferably in the interval 1° -20°.

摘要： A combustion chamber (7) in an engine (1) comprising with a piston (3), an injector (13) with plurality of orifices arranged to inject spray/ flame plumes, which impinge on a piston outer bowl section during most of the injection. Between spray/ flame plume impingement areas and in a plane substantially perpendicular to reciprocal piston movement are arranged a first type of protrusions protruding into the combustion chamber (7), having a smooth form for preserving kinetic energy in the flame and for redirecting circumferential flame progress mainly towards a center axis of the piston (3) with minimal flame-to-flame interaction. A second type of protrusions are arranged in the impingement areas, being adapted for redirecting flame progress into a circumferential flame progress direction in a plane substantially perpendicular to said reciprocal piston movement and with minimal flame-to-piston wall interaction and minimal kinetic energy loss.

摘要： Arrangement for purification of hot exhaust gases from internal combustion engines and comprising a housing provided with a gas inlet (6) and a gas outlet (7) for the flow of gases through the inside of the housing, and a gas purification unit arranged in the housing between the gas inlet and the gas outlet. Between the peripheral casing wall (20) of the purification unit (16) and the wall of the housing there is a closed, gas-tight element (23) which extends peripherally round the purification unit and through the heat-insulating layer and is designed as a three-dimensional shell with an inner attachment (26) on the casing wall of the purification unit and an outer attachment (25) on the wall (8, 9) of the housing. The inner attachment is situated at a level which is nearer the outlet side of the purification unit than the level of the outer attachment. In this way the gas-tight element with its inner and outer attachments forms a gas-tight securing arrangement for the purification unit in the housing with minimal heat losses.
