Abstract

A control system for a homogeneous charge compression ignition (HCCI) engine includes first and second modules. The first module determines an adjusted intake valve opening (IVO) timing based on a base IVO timing and an IVO timing adjustment, wherein the IVO timing adjustment is based on one or more of a plurality of operating parameters. The second module controls intake valves of the HCCI engine based on the adjusted IVO timing.
