Abstract: Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, an intake valve timing, exhaust valve timing of a first set of exhaust valves coupled to the first exhaust manifold, and a position of an exhaust gas recirculation (EGR) valve in an EGR passage may be adjusted in coordination with one another in response to a condition at a compressor. The EGR passage may be coupled between the intake passage, upstream of the compressor, and the first exhaust manifold.

Abstract: Methods and systems are provided for coordinating operation of a high pressure EGR control loop with a boost pressure control loop. In one example, following a tip-in, turbine vane position may be adjusted as a function of a maximum permissible exhaust pressure upstream of a turbocharger turbine. The maximum permissible exhaust pressure may be determined as a function of a HP EGR valve position at the time of the tip-in.

Abstract: An EGR (exhaust gas recirculation) cooler includes a cylinder block having a mounting space and having a coolant inlet in which a coolant can flow into the mounting space and a coolant outlet in which the coolant can be exhausted. A cover plate covers the mounting space and forms an exhaust inlet though which the exhaust gas can flow in and an exhaust outlet through which the exhaust gas can be exhausted. Tubes are mounted in the mounting space and through which the exhaust gas can flow. An inlet tank is mounted in the mounting space and is configured to distribute the exhaust gas flowing through the exhaust inlet of the cover plate to the tubes. An outlet tank is mounted in the mounting space and is configured to guide the exhaust gas exhausted from the tubes to the exhaust outlet of the cover plate.

Abstract: A turbocharger system includes a valve assembly with an inlet, a first outlet, and a second outlet. The inlet is configured for receiving flow of an exhaust gas from an engine. The valve assembly includes a valve structure disposed within a housing. The valve structure is configured to rotate about an axis of rotation between a first position and a second position. The valve structure defines a nonlinear flow passage with an axial upstream end and radial downstream end. The valve structure, in a first position, directs exhaust gas from the inlet to the first outlet and closes off the second outlet. The valve structure, in the second position, directs exhaust gas from the inlet to the second outlet and closes off the first outlet.

Abstract: An engine and a method of operating the engine wherein fuel, intake air, and recirculated exhaust gas provides a first mixture, which is inducted into a first combustion cylinder. The first mixture is combusted in the combustion cylinder to generate a first exhaust gas that applies pressure to a piston within the combustion cylinder, reciprocating the piston and rotating a primary crankshaft coupled to the piston. Fuel and intake air, which provides a second mixture, are inducted into a rotary combustion chamber. The second mixture is combusted in the rotary combustion chamber, wherein the combustion generates a recirculated exhaust gas that applies pressure to the rotor and rotates the rotor and a secondary crankshaft coupled to the rotor. The secondary crankshaft is coupled to the primary crankshaft by a gear mechanism. The recirculated exhaust gas is exhausted into an exhaust gas recirculation loop and recirculated.

Abstract: Methods and systems are provided for regenerating an exhaust particulate filter during an engine non-combusting condition. In one example, a method may include, responsive to a higher than first threshold soot load on the PF and a higher than threshold PF temperature, regenerating the PF by flowing compressed air through the PF via operation of an electric booster coupled to the intake manifold.

Abstract: A system includes an internal combustion engine having a number of cylinders, with at least one of the cylinders plumbed to have a complete recycle of the exhaust gases from the cylinder. The system further includes the completely recycled cylinder having an EGR stroke cycle, and the non-recycled cylinders of the engine having an exhaust stroke cycle. The system includes the EGR stroke cycle being distinct from the exhaust stroke cycle. An amount and composition of the exhaust gases from the recycled cylinder are distinct from the amount and composition of the exhaust gases from the non-recycled cylinders, at least at certain operating conditions of the engine.

Abstract: Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, during a cold start, a method may include adjusting a position of a first valve disposed in an exhaust gas recirculation (EGR) passage based on an engine operating condition, the EGR passage coupled between the first exhaust manifold coupled to a first set of exhaust valves and the intake passage, upstream of a compressor. As one example, the engine operating condition may include an engine temperature or a temperature of a catalyst disposed in the exhaust passage.
