Abstract
A method of controlling components in an air intake system for an internal combustion engine (10) uses sequential control. The method includes sequentially controlling the operation of a plurality of components (130, 132, 134) of an air intake system to control an excess air ratio for the engine, including identifying a deviation between an actual value of a parameter indicative of an excess air ratio and a desired value, controlling the first component (130) at a first time, and controlling the second component (132) at a second time that is later than the first time. The controlled components may be a turbo air bypass valve and a turbo wastegate valve.
