The invention relates to a method for regeneration of a nitrogen oxide storage catalyst (160) for a direct injected compression ignition engine comprising a controllable fuel injection system (170) and means (120, 125, 140) for controlling swirl ratio. Acc...

An injector 11 is disposed at such an angle that an injection nozzle 11a is arranged opposite to intake valve openings 3e and a mixture of a fuel injected from the injection nozzle 11a and air generates air motion in a cylinder. The air-fuel mixture is dir...

A cylinder head (1) of an internal combustion engine comprises a structure cast (1) in metal, the structure defining therein an intake port (3) and having a side wall surface (5) from which an upstream end of the intake port (3) is exposed to the outside; ...

The device (1) has positioning aids (5,6) on both sides with a deformation section (9,10) for force-locking fixing between associated cast stops (8). The deformation sections have through openings (11,12) in the form of elongated holes and are elastically ...

The present invention provides a fuel injection device comprising an intake pipe (18) having interior wall surfaces (18b) for providing air from an upstream side to a downstream side and a fuel injection port (52) disposed in the intake pipe (18) between t...

The charge intake for a motor vehicle internal combustion engine has a divided duct (24) with the outer walls of the divided channel section leading up to the intake ports shaped to control the charge slow. The outer walls can be curved inwardly (68) to fo...

The charge intake for a motor vehicle internal combustion engine has an intake duct (24) with an upstream section (26) divided into two sections downstream (28,30) which open into the combustion chamber (22) via two ports (32,34) each with a valve (36,38)....
