Abstract: There is disclosed an exhaust manifold comprising a plurality of exhaust intake conduits and an exhaust intake manifold. Each of the plurality of exhaust intake conduits is structured to be fluidly coupled to an engine and structured to receive exhaust gas from a corresponding cylinder of the engine. The exhaust intake manifold is fluidly coupled to an exhaust intake conduit outlet of at least one of the plurality of exhaust intake conduits. Each of the plurality of exhaust intake conduits and the exhaust intake manifold define an exhaust intake manifold core volume. Each of the plurality of exhaust intake conduits and the exhaust intake manifold are shaped so as to define the exhaust intake manifold core volume based on at least one of the displacement of the engine, the intended operating power of the engine, and the intended flow rate of the exhaust gas through the exhaust manifold.

Abstract: An exhaust gas recirculation arrangement is provided for a power system, the power system including an internal combustion engine, an exhaust gas system and an intake system including an inlet air compressor, the exhaust gas recirculation arrangement including a first exhaust gas recirculation path and a second exhaust gas recirculation path for recirculating exhaust gas from the exhaust gas system to the intake system. The first and second exhaust gas recirculation paths are adapted to recirculate exhaust gas to the same side of the inlet air compressor, in an intended direction of flow of inlet air in the power system, wherein the exhaust gas recirculation arrangement includes a flow controller, preferably the flow controller includes a valve connected to the second exhaust gas recirculation path, for controlling the flow volume through at least one of the first and second exhaust gas recirculation paths.

Abstract: A method of operating an internal combustion engine having a plurality of cylinders (1, 2, 3) and pistons (4, 5, 6) respectively supported therein. During an expansion stroke of the piston (4, 5, 6) of at least one of the cylinders (1, 2, 3), combusted gas from said at least one cylinder is delivered to at least one other cylinder. Delivery is effected by the pressure differential between the gases in the at least one cylinder supplying the gas and the at least one other cylinder receiving the gas. Further, the gas is delivered from the at least one cylinder to the at least one other cylinder independently of the exhaust system of the engine.

Abstract: An engine system (10) comprises an internal combustion engine (12) with two sets of cylinders (16, 22), a turbocharger (28), two exhaust conduits (30, 32) providing fluid communication between the turbocharger and the exhaust of the sets of cylinders, and an exhaust gas recirculation system (34) comprising a recirculation valve (38). Two proportional exhaust valves (42, 46) are adapted to control a flow of exhaust gas in the two exhaust conduits. The engine system comprises an actuator (50) comprising an output component operating the recirculation valve and the two exhaust valves. In a neutral position, the two exhaust valves are open and the recirculation valve is closed. A first movement of the output component, from its neutral position towards a first position, open the recirculation valve and close a first of the two exhaust valve. A second movement, from the first position and in the same direction as the first movement, close the second exhaust valve and hold open the recirculation valve and closed the first exhaust valve.
