摘要： An EGR passage of an EGR device includes a plurality of EGR introduction passages and an EGR chamber. A plurality of cylinders include a first cylinder subset and a second cylinder subset, each of which is a pair of two cylinders positioned next to each other. An explosion interval between the two cylinders constituting the first cylinder subset is shorter than that of the second cylinder subset. A first total volume being the sum of volumes of two first EGR introduction passages associated with the first cylinder subset and a volume of a portion of the EGR chamber located between the two first EGR introduction passages is larger than a second total volume being the sum of volumes of two second EGR introduction passages associated with the second cylinder subset and a volume of a portion of the EGR chamber located between the two second EGR introduction passages.

摘要： An internal combustion engine includes low and high pressure turbochargers connected in series. An engine cylinder has an intake valve that fluidly connects a main chamber of the engine cylinder with an outlet of the high pressure compressor through an intake passage. An exhaust gas recirculation passage is fluidly interconnected between exhaust and intake conduits. A pre-chamber encloses a spark plug and is fluidly open with the main chamber of the engine cylinder. A first fluid path extends from the intake passage directly to the pre-chamber, and a second fluid path extends from the intermediate passage directly to the pre-chamber.

摘要： 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, each of a first valve positioned in an exhaust gas recirculation (EGR) passage, the EGR passage coupled between the intake passage and the first exhaust manifold coupled to a first set of cylinder exhaust valves, and a second valve positioned in a flow passage coupled between the first exhaust manifold and the exhaust passage may be adjusted based on a measured pressure in the first exhaust manifold.

摘要： 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, in response to an electric motor driving an electric compressor positioned upstream of a turbocharger compressor disposed in the intake passage, a position of a valve in an exhaust gas recirculation (EGR) passage coupled between the intake passage and the first exhaust manifold may be adjusted based on a pressure in the first exhaust manifold.

摘要： 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, one or more valves of a set of first exhaust valves coupled to the second exhaust manifold may be deactivated in response to select engine operating conditions, while maintaining active all valves of a set of second exhaust valves coupled to the first exhaust manifold. The select engine operating conditions may include one or more of a deceleration fuel shut-off condition, a part throttle condition, and a cold start condition.

摘要： 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, a method may include decreasing gas flow from the first exhaust manifold to the intake passage, upstream of a compressor, where a first set of exhaust valves are exclusively coupled to the first exhaust manifold, in response to a condition of the compressor. Further, the method may include increasing gas flow from the first exhaust manifold to an exhaust passage coupled to a second exhaust manifold coupled to a second set of exhaust valves, in response to the decreasing gas flow.
