Claim 12:
13. An engine, comprising:
a turbocharger comprising a turbine section;
multiple cylinders, wherein each cylinder comprises a combustion chamber and a piston slidably positioned in the cylinder;
multiple exhaust valves, wherein each exhaust valve is positioned in an exhaust port of each of the multiple cylinders;
exhaust branch passages fluidly connecting the multiple exhaust valves to an exhaust pulse valve;
an exhaust main passage fluidly connecting the exhaust pulse valve to a turbine inlet of the turbine section of the turbocharger; and
a computer system having a non-transitory computer readable medium in communication with the multiple exhaust valves and the exhaust pulse valve, the non-transitory computer readable medium storing instructions comprising functionality for:
actuating the exhaust pulse valve to a fully open position when at least one of the multiple exhaust valves is open, wherein when the exhaust pulse valve is in the fully open position, the exhaust branch passages are in fluid communication with the exhaust main passage; and
actuating the exhaust pulse valve to a fully closed position when the multiple exhaust valves are closed, wherein when the exhaust pulse valve is in the fully closed position, the exhaust branch passages are sealed from the exhaust main passage.
