Abstract: An exhaust system includes a plurality of cylinders, and each cylinder includes a scavenge exhaust valve and a blowdown exhaust valve. A scavenge path leads from the scavenge exhaust valves and a blowdown path leads from the blowdown exhaust valves. An arrangement activates and deactivates the scavenge exhaust valves and the blowdown exhaust valves. Further included is a cam shaft including a plurality of scavenge cams and a plurality of blowdown cams. During rotation of the cam shaft, the scavenge cams interact with the scavenge exhaust valves to open and close the scavenge exhaust valves when the scavenge exhaust valves are activated. Additionally, during rotation of the cam shaft, the blowdown cams interact with the blowdown exhaust valves to open and close the blowdown exhaust valves when the blowdown exhaust valves are activated, and at different times with respect to the opening and closing of the scavenge exhaust valves.

Abstract: A method includes providing an internal combustion engine having a combustion chamber, a piston movably disposed in the combustion chamber, and a prechamber connected to the combustion chamber via a flow port. The method further includes forcing a gas mixture from the combustion chamber through a zeolite material to the prechamber using a compression stroke of the piston, where the zeolite material filters the gas mixture to provide an oxygen rich gas into the prechamber.

Abstract: A fuel injector includes an injector body with a fuel chamber configured to receive fuel from a fuel line, an injector tip provided at an end of the injector body, and one or more nozzle assemblies provided in the injector tip. The one or more nozzle assemblies have a fuel channel in fluid communication with the fuel chamber, a premixing tube fluidly connected to the fuel channel, and a port fluidly connected to the premixing tube. The premixing tube has an orifice providing an outlet for the injector tip.

Abstract: A residual gas ignitor for use in igniting a fuel-air mixture within a main combustion chamber of an engine. The residual gas ignitor includes at least one inlet/outlet port, a residual gas ignitor chamber for receiving a combustion gas from the main combustion chamber, an ignitor valve for opening and closing the at least one inlet/outlet port, an actuator for actuating the ignitor valve to open and close the at least one inlet/outlet port, a valve guide for keeping the ignitor valve in a correct orientation within the residual gas ignitor, a preload spring for being in compression when the actuator disposes the ignitor valve into the closed position, and a heating element for maintaining or increasing a temperature of the combustion gas while the combustion gas is in the residual gas ignitor chamber. The residual gas ignitor may be used in engines for initiating combustion of fuel-air mixtures.

Abstract: A prechamber device includes an enclosure body and a cap forming an enclosed volume. The enclosure body has an orifice at one end. A precombustion chamber is defined within the enclosed volume and is in fluid communication with the orifice. A valve plug is movable along an axial axis of the enclosure body to adjust a valve opening at the orifice to a range of positions from a fully open position to a closed position. An actuator is coupled to the cap and the valve plug and is controllable to displace the valve plug along the axial axis of the enclosure body. The prechamber device is operable to generate turbulent jets that are directed into a main combustion chamber of an engine cylinder through the valve opening. During an engine cycle, the valve opening is controlled between the range of positions based on detected engine speed and engine load.
