Abstract: Methods and systems are provided for an exhaust-gas aftertreatment device. In one example, an exhaust-gas aftertreatment device comprises a housing with a first can comprising a first catalytic converter and a second can comprising a second catalytic converter, wherein the first catalytic converter is not concentric with the first can.

Abstract: Systems are provided for an integrated exhaust manifold that may be used in a variety of engine systems. In one example, an integrated exhaust manifold may include a central axis running from an inlet end to an outlet end of the integrated exhaust manifold and two exhaust outlets arranged at the outlet end and coupled to a common collecting line, the two exhaust outlets symmetrically positioned across the central axis and having a same diameter, where each exhaust outlet of the two exhaust outlets has a passage axis arranged parallel to the central axis. A first exhaust outlet of the two exhaust outlets may be permanently blocked and a second exhaust outlet of the two exhaust outlets may be coupled to an exhaust system of an engine system.

Abstract: An internal combustion engine with coolant jackets is provided. The internal combustion engine includes a cylinder head coupled to a cylinder block to form a first cylinder, an upper head-associated coolant jacket including a coolant conduit traversing the cylinder head, a lower head-associated coolant jacket fluidly separated from the upper cylinder head coolant jacket and including a coolant conduit traversing the cylinder head vertically below the upper head-associated coolant jacket, and a block-associated coolant jacket including, a first coolant passage having an inlet in fluidic communication with a coolant pump outlet and an outlet in fluidic communication with an inlet of the lower head-associated coolant jacket, and a second coolant passage having an inlet in fluidic communication with an outlet of the lower head-associated coolant jacket and an outlet in fluidic communication with a heat exchanger.
