ABSTRACT:
An intake and fuel/air mixing system for multi-cylinder externally ignited internal combustion engines with at least two inlet valves per cylinder, at least two separate intake pipe arms per cylinder assigned to the inlet valves, and fuel injection. The first intake pipe arms per cylinder are combined into a first group and other intake pipe arms per cylinder are combined into at least one other group. Each group is assigned one throttling member. The first group comprises a common fuel injection, and one injection each is assigned to the intake pipe arms or inlet ports of the other group or other groups. The throttling members of the individual groups are controlled in such a manner that for the region of low air flow rates the first group opens first and the other group or other groups are opened as a function of the speed and load with higher air flow rates.
