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.
