Methods and systems are provided for an exhaust system. In one example, the exhaust system includes an aftertreatment device and a recirculation passage. A recirculation valve is positioned in the recirculation passage and configured to control an amount of recirculated exhaust gas flowing through the recirculation passage to the aftertreatment device. The exhaust system further includes a diverter valve configured to control a flow of engine exhaust gases to different portions of a catalyst of the aftertreatment device.

Methods and systems are provided for a resonator of an exhaust system. In one example, the resonator is a quarter wave resonator with a diaphragm configured to provide pulsations during low-end engine torque conditions.

Exhaust-gas aftertreatment arrangement

Methods and systems are provided for a heating device. In one example, a system comprises a heat exchanger and an air filter arranged in a common housing, wherein the heat exchanger is configured to receive coolant from a heating device. In one example, the heating device is an electric heating device.

Methods and systems for a turbocharged engine

Methods and systems are provided for an aftertreatment system. In one example, a method comprises regenerating a NOtrap during an engine shut-down event. The method further comprises reversing a direction of flow of a gas through a HP-EGR passage during the regenerating.

Methods and systems are provided for an internal combustion engine having an oil circuit. In one example, a system may include a rising oil line from a block to a cylinder head of an engine; a main oil line in the head; and an oil siphon system including a reservoir positioned between, and having at least one portion at a lower elevation than both, a section the rising line and a section of the main oil line so that oil flows into, and remains in, the reservoir when the engine is shut-off. In this way, the design of the oil circuit may be used to improve oil supply to engine components while minimizing delays in oil supply during engine startup.

Methods and systems are provided for an auto-ignition internal combustion engine comprising an exhaust gas recirculation arrangement, an intake system, and an exhaust gas discharge system for the discharge of exhaust gases, in which the internal combustion engine is operable, at least in a first, stoichiometric operating mode, by way of a spatial ignition method (HCCI mode). For the aftertreatment of the exhaust gas in the first operating mode, a three-way catalytic converter is provided in the exhaust gas discharge system for reducing nitrogen oxides and oxidizing unburned hydrocarbons and carbon monoxide. In this way, the auto-ignition internal combustion engine has a greater window of operation in the HCCI mode than conventional auto-ignition internal combustion engines.

The disclosure relates to a supercharged internal combustion engine with an intake system and an exhaust gas discharge system that include two turbochargers arranged in series, a turbo-generator, and an electrically-driven compressor. During engine operation with mid-to-high exhaust gas flow rates, excess exhaust gas that bypasses the high-pressure turbocharger may be directed through the turbo-generator to generate electricity that may be provided to drive the electrically-driven compressor.

The present disclosure concerns a charge cooler with an air cooler in a first air path and with a bypass in a second air path which is connected in parallel to the first air path, wherein a thermal insulation is assigned to the bypass which thermally isolates the bypass from the air cooler, wherein the air cooler has a double-walled base body with an outer wall and with an inner wall, wherein the thermal insulation is arranged on the inner wall. The present disclosure also concerns a valve for such a charge cooler, and a turbo-charged internal combustion engine with such a charge cooler, and a motor vehicle with such an internal combustion engine.
