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 for an aftertreatment system

Methods and systems are provided for a condensation mitigation device. In one example, a system may include a vortex generator arranged in a flow channel of a compressor along with a condensate collection device configured to direct condensate away from compressor blades of the compressor.

Methods and systems for mitigating condensate formation

Methods and systems are provided for a mixing chamber in a turbine. In one example, a system comprises a mixing chamber integrally formed within a turbine with an injector positioned to inject reductant directly into the mixing chamber.

Methods and systems for a mixing chamber

Methods and systems are provided for an exhaust gas system. In one example, a system comprises a conical passage fluidly coupling a turbine outlet to an aftertreatment device. The conical passage may further comprise a scavenge valve to adjust exhaust gas flow therethrough.

Methods and systems for an exhaust system

Methods and systems are provided for an exhaust-gas arrangement. In one example, a system may include a barrier dividing an intake passage into first and second portions to mitigate exhaust-gas recirculate mixing with charge air upstream of a compressor.

Methods and systems for exhaust-gas recirculation

Methods and system are provided for a flap valve having a sealing element. In one example, a system include a front side of the flap valve having a first sealing element and a back side of the flap valve having a second sealing element, where the first sealing element and the second sealing element are located along a circumferential edge of the flap valve and spaced away from its geometric center.

Internal combustion engine with compressor, exhaust-gas recirculation arrangement and pivotable flap

A control device for an internal combustion engine includes an intake channel with an inlet and an outlet, a control element, an exhaust gas recirculation channel with an opening, a recirculation channel, and a shaft having the control element eccentrically mounted thereon. The exhaust gas recirculation channel enters the intake channel. The opening of the exhaust gas recirculation channel is a valve seat for the control element. The shaft acts as an axis of rotation for the control element. A rotation of the shaft moves the control element between a first end position where the control element throttles the intake channel and a second end position where the control element contacts the valve seat at the opening of the exhaust gas recirculation channel. The axis of rotation is arranged in a plane which passes through the valve seat at the opening of the exhaust gas recirculation channel.

Control device for an internal combustion engine

A control device for an internal combustion engine includes an intake channel, an exhaust gas recirculation channel which enters into the intake channel, a control element, a mixing housing which forms the intake channel, a connection element, a compressor, and a shaft. The mixing housing has a mouth of the exhaust gas recirculation channel in a lower area, an outlet, a mixing housing section, and a bowl-shaped recess. The cross-sectional extension is formed via the mixing housing to provide an axial stop face. The connection element abuts against the axial stop face and is radially limited by an axially opposite inner wall surface on the stop face. The mixing housing section has a recess arranged at the lowest point of the mixing housing section and below the axially opposite inner wall surface. The recess enters into the bowl-shaped recess of the mixing housing.

Methods and systems are provided for a turbocharger comprising a compressor inlet shaped to mitigated condensate formation therein. In one example, system may include a condensate trap which runs along an inner wall of the compressor inlet and is shaped to trap condensate.

The disclosure relates to a supercharged, direct-injection internal combustion engine having an intake system for the supply of charge air and having an exhaust-gas discharge system for the discharge of exhaust gas and having at least two series-connected exhaust-gas turbochargers which each comprise a turbine arranged in the exhaust-gas discharge system and a compressor arranged in the intake system and of which a first exhaust-gas turbocharger serves as a low-pressure stage and a second exhaust-gas turbocharger serves as a high-pressure stage, a first bypass line being provided which branches off from the exhaust-gas discharge system between the first turbine and the second turbine so as to form a first junction point.

Methods and systems for a two-stage turbocharger

Methods and systems are provided for an EGR cooler having first and second coolant jackets fluidly coupled to first and second coolant systems, respectively. In one example, the first and second coolant jackets are hermetically sealed from one another. Furthermore, the second coolant jacket protrudes into a portion of an exhaust gas passage directly downstream of an exhaust aftertreatment device.
