Abstract
An engine having one of a plurality of exhaust valves in each cylinder that may be deactivated is disclosed. In one example, one exhaust valve of each cylinder is deactivated in response to engine speed. The engine may have improved engine torque at low engine speeds and reduced time to torque (e.g., turbo lag).
