First Claim
Patent Images
1. A method for controlling an intake system in a motor vehicle comprising the steps of:
- determining a current cylinder mode from a plurality of cylinder modes;
receiving information related to a parameter associated with an operating condition of the motor vehicle unrelated to the plurality of cylinder modes;
selecting a predetermined range associated with the current cylinder mode, the predetermined range being a range of values over which a first intake mode should be used;
comparing the parameter with the predetermined range, the predetermined range having a lower limit and an upper limit; and
within the current cylinder mode, using the first intake mode when the parameter is within the predetermined range and using a second intake mode when the parameter is outside the predetermined range,wherein the first intake mode is a first configuration of the intake system that is tuned for particular resonances of pressure waves when the parameter is within the predetermined range.

Abstract
A method and a system for controlling an intake system for an engine is disclosed. The method includes steps for selecting an intake mode according to the current engine speed and the current cylinder mode. The method may be used for controlling an intake system in conjunction with a multi-displacement engine having one or more cylinders that may be deactivated.
