摘要： Arrangement (1) to insert a liquid medium into exhausts from a combustion engine, comprising : - a mixing chamber (2) intended to be perfused by exhausts and delimited in a radial direction outwards by a first tubular metal wall (6), and - an injection element (10) for injection of the liquid medium as a spray (11) into the mixing chamber, and - an exhaust channel (12) extending along the outside of the first tubular wall. The exhaust channel (12) is delimited in a radial direction outwards by a second tubular wall (13), which guides the exhausts flowing through the exhaust channel so that they pass on the outside of the wall section (6a) of the first tubular wall which is intended to be impacted by said spray. A throttle (14) is arranged in the section (12a) of the exhaust channel which is located on the outside of said wall section (6a) in order to accelerate the exhausts so that these flow with an increased speed over the outside of said wall section (6a).

摘要： A phase- shifting device (29), a so-called cam phaser, is arranged between a crankshaft and at least one camshaft (20,23) to change the at least one camshaft's (20, 23) rotational position in relation to the crankshaft (15) and thus push forward or defer at least one inlet valve's and/or at least one exhaust valve's opening and closing time. The phase- shifting device (29) is connected to an accumulator (60) that can be charged by an oil pump (6). The oil pressure may be increased with the help of a pressure medium controlled cylinder (71) before or during a phase- shifting process.

摘要： A valve drive of an internal combustion engine comprises a camshaft (3) with a base shaft (4), a lobe pack (6) mounted on the base shaft and comprising three cam lobes (7-9). Two actuator bodies (11, 12) are associated with two actuator pins (13, 14) each connected to a valve (15, 16) of a cylinder of the engine. The lobe pack is axially displaceable along the base shaft so as to for each actuator body change cam lobe aligned therewith. A middle cam lobe (8) has a shape leaving an actuator body aligned therewith uninfluenced thereby. In a first position of the lobe pack a first (11) of the actuator bodies is aligned with and hit and moved by a first cam lobe (7) and the other, second actuator body (12) is aligned with the middle cam lobe, and in a second position the second actuator body (12) is aligned with and hit and moved by a third cam lobe (9) and the first actuator body (11) is aligned with the middle cam lobe (8).
