    摘要: A method of operating a multiple cylinder internal combustion engine in a four-stroke cycle. A first amount of fuel is introduced into each of the cylinders (10) earlier than 45 degrees before top dead center of a combustion stroke. Air significantly in excess of that providing a stoichiometric amount of oxygen is also introduced into each cylinder to produce a first mixture upon introduction of the fuel, which mixture is ignited to produce a first combustion event. Subsequent to substantial completion of the first combustion event, but prior to top dead center in the same combustion stroke or shortly after top dead center in the expansion stroke, a second amount of fuel is introduced into each cylinder without additional air to form a second mixture which is ignited to produce a second distinct combustion event.

    摘要: When fuel is injected into a combustion chamber (2) of a cylinder (13) of an engine (30) of a vehicle (10), fuel is injected in the form of multiple jets (3) by means of an injector (1). In this context, a first plane is defined in which both the central axis (11) of the injector (1) and the central axis (12) of the cylinder (13) are located. Furthermore, a second plane is defined in which both the central axis (11) of the injector (1) and the surface normal of the first plane lie. The jets (3) are generated in such a way that, for each jet pair which is formed from two of the jets (3), an angle between the projections of the two central axes of the two jets of the jet pair into the second plane is less than 50°.
