ABSTRACT:
A vapor recovery control system for a direct injection spark ignition engine is used to purge vapors in both a homogeneous air/fuel and stratified air/fuel mode. When purging vapors in a stratified mode, a portion of the cylinders receive purge vapors and operate in a homogeneous mode while the rest of the cylinders continue to operate in a stratified mode.
