Method for operating a supercharged internal combustion engine and device for providing combustion air for a supercharged internal combustion engine

An internal combustion engine comprising:

• at least one cylinder group with a number of n combustion chambers, wherein, during a first operating state, all n combustion chambers are supplied with combustion air via a primary charge air path and, during a second operating state, only a portion of the n combustion chambers are supplied with combustion air from the primary charge air path and another portion of the n combustion chambers are supplied with combustion air from a separate compressed air reservoir.

A system which is operated by a dynamically operated internal combustion engine, in an on-road, off-road or an off-highway system with a device for providing combustion air in the dynamically operated internal combustion engine, wherein the device contains two or more separate air manifolds, a primary charge air path containing at least one apparatus for compressing the charge air, and at least one compressed air reservoir, wherein a valve arrangement is provided in order to supply the two or more air manifolds selectively with combustion air through the primary charge air path or alternatively to supply only a portion of the two or more separate air manifolds with combustion air from the primary charge air path, while (i) the entire remaining portion of the two or more separate air manifolds or (ii) only a sub-group of the remaining portion of the two or more separate air manifolds can be supplied with combustion air from the compressed air reservoir.
