Abstract
An internal combustion engine has at least two exhaust ports and a valve assembly. The valve assembly has first and second connectors, first and second actuator pistons connected to their corresponding connectors, the first and second actuator pistons being disposed in first and second chambers respectively, and first and second valves connected to their corresponding connectors. The first connector, actuator piston and valve are movable together between first and second positions. The second connector, actuator piston, and valve are movable together between first and second positions. A first fluid line supplies hydraulic fluid in the first and second chambers on a first side of the first and second actuator pistons. A second fluid line supplies hydraulic fluid in the first and second chambers on a second side of the first and second actuator pistons. At least one fluid pump supplies hydraulic fluid to the first and second fluid lines.
