The engine block including a plurality of cylinders defining a plurality of combustion chambers each comprising one of a cylinder head and a piston. Each of the plurality of cylinder heads includes an exhaust valve and an intake valve. The engine system further includes a first control valve, a second control valve, rocker lever, and an auxiliary rocker lever. The first control valve is coupled to the camshaft and configured to activate the rocker lever. The second control valve is coupled to the camshaft and configured to activate the auxiliary rocker lever. The rocker leaver is configured to actuate the at least one exhaust valve to allow exhaust gas to flow out of at least one of the plurality of cylinders. The auxiliary rocker lever is configured to actuate at least one of the plurality of exhaust valves to allow exhaust to flow into the cylinder.",
