An intake device is provide for drawing in fresh gas and feeding the same to an internal combustion engine with internal combustion, wherein the intake device is suited for the formation of a fresh gas vortex in a combustion chamber of the internal combustion engine. The intake device includes a first manifold section, from which all first parts of fresh gas line groups branch off to a fresh gas outlet end, and a second manifold section, from which all second parts of the fresh gas line groups branch off to the fresh gas outlet end, which are fluidically separated from each other from the separation point to the fresh gas outlet end. A vortex throttle assembly is provided in a first manifold section and the amount throttle device is provided in the second manifold section. |

1. An intake device for drawing in fresh gas and feeding the same to an internal combustion engine with internal combustion, wherein the intake device is suited for the formation of a fresh gas vortex in a combustion chamber of the internal combustion engine and comprises:
a fresh gas net end farthest from the internal combustion engine in a fully assembled state, a fresh gas outlet end nearest to the internal combustion engine in a fully assembled state, a fresh gas heat exchanger for transmission of thermal energy between the fresh gas and a heat exchanger medium flowing through the fresh gas heat exchanger provided between the fresh gas net end and the fresh gas outlet end, an inlet-side fresh gas line for feeding fresh gas from the fresh gas net end to the fresh gas heat exchanger, an amount throttle device configured for the purpose of modifying the amount of fresh gas, which flows per time unit from the fresh gas net end to the fresh gas outlet end during operation of the intake device, a plurality of separate outlet-side fresh gas lines configured for feeding fresh gas in the direction from the fresh gas heat exchanger to the individual combustion chambers of the internal combustion engine, wherein a fresh gas line group is provided with at least two separate outlet-side fresh gas lines for each combustion chamber to be supplied with fresh gas by the intake device, and a vortex throttle assembly configured for the modification of the amount of fresh gas, which flows per time unit through a first part of the outlet-side fresh gas lines of each fresh gas line group during operation of the intake device,wherein an amount of fresh gas, which flows per time unit through a second part of the outlet-side fresh gas lines of each fresh gas line group, which is different from the first part, can be modified during operation of the intake device by actuating the amount throttle device, wherein a first manifold section, from which all first parts of the fresh gas line groups branch off to the fresh gas outlet end, and a second manifold section, from which all second parts of the fresh gas line groups branch off to the fresh gas outlet end, are fluidically separated from each other from a separation point on downstream to the fresh gas outlet end, such that from the separation point to the fresh gas outlet end the first manifold section and all other first parts of the fresh gas line groups form a first flow chamber and the second manifold section and all second parts of the fresh gas line groups form a second flow chamber, wherein the vortex throttle assembly is provided in the first manifold section and the amount throttle device is provided in the second manifold section. |
