Abstract
Methods and systems are provided for reducing air flow to an emission control device during a fuel shut-off event. In one example, a method may include adjusting a timing of an exhaust valve and a timing of an intake valve of a cylinder during the fuel shut-off event using a common actuator. The actuator may include a planetary gear system configured to rotate a first portion of a camshaft in a first direction and a second portion of the camshaft in a second, opposite direction.
