## Abstract

A method is provided for controlling an engine via an outlet control device of an intake manifold, such as via variable valve lift operation. The engine may further include an inlet control device, such as an electronic throttle, as well as coordination between the inlet and outlet control devices for controlling airflow in the engine.

## Claims

### Claim 1

A method for controlling an engine having an intake manifold and an outlet control device coupled to the manifold for controlling flow exiting the manifold and entering at least one cylinder of the engine, the engine further having an inlet control device for controlling flow entering the manifold, the method comprising: determining a driver torque command; calculating a desired cylinder charge based on said driver torque command; and adjusting the outlet control device to provide said desired cylinder charge.
