24 Aug 1998TL;DR: In this paper, a plurality of the cylinders are divided into a first cylinder group and a second cylinder group, and each cylinder group is connected, via a corresponding branch exhaust passage, to a common interconnecting exhaust passage.
Abstract: An engine has a plurality of the cylinders. The cylinders are divided into a first cylinder group and a second cylinder group, and each cylinder group is connected, via a corresponding branch exhaust passage, to a common interconnecting exhaust passage. In the interconnecting exhaust passage, an exhaust gas purifying catalyst is arranged. The air-fuel ratio of the exhaust gas of the first cylinder group is made lean to feed oxygen to the exhaust gas purifying catalyst, and the air-fuel ratio of the second cylinder group is made rich to feed fuel for heating to the exhaust gas purifying catalyst, so that the oxygen and the fuel for heating react with each other to heat the exhaust gas purifying catalyst to reactivate the exhaust gas purifying catalyst when the reactivation of the exhaust gas purifying catalyst is must be performed. In each branch exhaust passage, a start catalyst is arranged.

TL;DR: In this paper, an internal combustion engine including an exhaust turbocharger and an exhaust-gas recirculation device, with an exhaust turbine and a compressor, has a plurality of inlet flow passages to which exhaust gas can be supplied via separate exhaust lines connected to some of the cylinders.
Abstract: In an internal combustion engine including an exhaust turbocharger and an exhaust-gas recirculation device, with an exhaust turbine and a compressor, the exhaust turbine has a plurality of inlet flow passages to which exhaust gas can be supplied via separate exhaust lines connected to some of the cylinders of the internal combustion engine In total, three flow passages are provided in the exhaust turbine, of which two communicate with the exhaust-gas recirculation device, and one of these flow passages includes an adjustable throttling member for regulating the mass flow of exhaust gas to be recirculated

2 Jun 1987TL;DR: A two-cycle internal combustion engine comprises a cylinder head having an intake port and exhaust port opened to a combustion chamber, to which compressed fresh air is introduced via an intake valve.
Abstract: A two-cycle internal combustion engine comprises a cylinder head having an intake port and exhaust port opened to a combustion chamber, to which compressed fresh air is introduced via an intake valve. The intake and exhaust valves are operated in response to a crank angle. A pulsation pressure of exhaust gas in the exhaust port is substantially restrained during an idling or light load running condition. The exhaust valve is opened earlier than the intake valve when the speed of the downward movement of the piston is relatively high, such that a part of exhaust gas in the exhaust port flows back to the combustion chamber in that condition. An exhaust gas swirl rotating around a cylinder axis is formed when the exhaust gas flows back and the fresh air is slowly introduced onto the exhaust gas swirl in that condition.

17 Jun 1991TL;DR: In this paper, a sequential turbocharger system for an internal combustion engine with an exhaust gas recirculation system is presented, where a bypass passageway is connected to an exhaust pipe to bypass the turbine of the small-volume turbochargers.
Abstract: A sequential turbocharger system for an internal combustion engine with an exhaust gas recirculation system. The sequential system includes a large-volume turbocharger and a small-volume turbocharger, which are arranged in series in the direction of the flow of gases. A bypass passageway is connected to an exhaust pipe to thereby bypass the turbine of the small-volume turbocharger, and an exhaust switching valve is arranged in the bypass passageway for controlling the flow of exhaust gas to the turbine of the small-volume turbocharger. The EGR system includes an exhaust gas recirculation passageway for introducing an amount of exhaust gas into the intake pipe of the engine. The exhaust gas for recirculation is taken out from the intake pipe at a position located between the turbines of the small-volume and large-volume turbochargers.
