Abstract: A motor system includes an engine having one or more cylinders, an electronic control unit, an exhaust treatment system in fluid connection with and downstream of the one or more cylinders. The exhaust treatment system includes an exhaust line, a combustion zone downstream, a combustion ignition source in the combustion zone, a catalyst downstream of an in thermal communication with the combustion zone. A method of heating a catalyst during an engine cold start and a method of initiating regular operating conditions of an engine having one or more cylinders are also described.

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.
