Abstract: The invention relates to an internal combustion engine system (100), comprising: —an internal combustion engine (2) comprising a cylinder block (3) housing a plurality of cylinders (4), a first intake manifold (6a) connected to a first group of cylinders (4a) a second distinct intake manifold (6b) connected to a second group of cylinders (4b) and a first, respectively a second, exhaust manifold (8a, 8b) for receiving the exhaust gas emitted from the first, respectively the second, group of cylinders (4a, 4b); —an air inlet line (10); —an EGR line (20) connected to the first and second exhaust manifolds (8a, 8b); wherein the internal combustion engine system is operable in at least two operating modes, respectively a normal operating mode in which all cylinders are supplied with fuel and a regeneration operating mode, in which the cylinders of the first group of cylinders (4a) are no longer supplied with fuel, characterized in that: —the system also includes a mixing unit (30) comprising a four-way valve, said

Abstract: A first intake manifold is connected to a first group of cylinders, a second distinct intake manifold is connected to a second group of cylinders and a first, respectively a second, exhaust manifold for receiving the exhaust gas emitted from the first, respectively the second, group of cylinders. An EGR line is connected to the first and second exhaust manifolds. A mixing unit includes a four-way valve having a first inlet connected to an air line, a second inlet connected to the EGR line, a first outlet connected to the first intake manifold and a second outlet connected to the second intake manifold. The first inlet is connected to the air line, the second inlet is connected to the EGR line. The first outlet and said second outlet form a substantially X-shape. The first inlet and said second inlet are coaxial. The first outlet and second outlet are coaxial such that the first inlet is diagonally facing the second inlet and the first outlet is diagonally facing the second outlet.

Abstract: The invention relates to an internal combustion engine system. The system includes a mixing unit comprising a four-way valve. The four-way valve having a first inlet connected to the EGR line, a second inlet connected to the air inlet line, a first outlet connected to the first intake manifold and a second outlet connected to the second intake manifold. The four-way valve is designed so that, in said normal operating mode, the intake gases supplied to the first intake manifold and to the second intake manifold have approximately the same proportion of exhaust gas and fresh air and so that, in said cylinder deactivation mode, the intake gas supplied to the first intake manifold only includes exhaust gas and the fresh air is directed exclusively to the second intake manifold.
