Definitions
- transition compensation is described for example in DE 10 2007 005 381 A1.
- fuel that has accumulated on the wall of the first intake manifold evaporates and enriches the air-fuel mixture that is directed into the combustion chamber.
- a particular advantage of this embodiment is to operate under different operating conditions, the engine particularly low emissions while ensuring uniform operation of the internal combustion engine.
- FIG. 3 a shows a schematic representation of a part of the internal combustion engine which carries out a second method step of a method according to an exemplary embodiment of the present invention, wherein FIG. 3 b and FIG. 3 c show the time change of an attached one
- Fuel quantity show and Figure 3 d shows the change over time of a lambda value.
