Abstract
A fuel vapor recovery system for a direct injection internal combustion engine operating in both stratified and homogenous modes includes using fuel vapor with air assisted injectors. A compressor compresses a controlled mixture of fresh air and fuel vapor which is then delivered to the air supply of air assisted injectors, allowing fuel vapors to be purged from the vapor recovery system during all engine operating modes.
