Abstract:
1. An internal combustion engine with at least two intake valves per cylinder, and at least two intake ports leading to the intake valves, a first intake port being configured as tangential passage and the flow through a second intake port being controlled by means of a first throttle element actuated in dependence of at least one engine parameter, and at least one fuel injector per cylinder injecting fuel into at least two intake ports, wherein in the closed position of the first throttle element at least one leakage aperture will permit a defined minimum flow through the second intake port, and wherein the first throttle element is positioned downstream of the fuel injector and at least one leakage aperture is provided in an area impinged on by at least one injection jet, and wherein the first throttle element in its closed position forms an obtuse angle of greater than 90° with a partition wall between the first and second intake port, so that the intake flow will be diverted towards the first intake port, wherein the first and second intake ports depart from a common manifold, and that the first throttle element is located in the branching area where the two intake ports branch off from the manifold.
