ABSTRACT:
A vapor recovery system has its purge valve opened with a time delay, following throttle opening, that allows the engine to get up to speed before vapor purging begins. However, the time delay varies, depending on how long the throttle has been closed. Therefore, if the throttle has been closed only a short time, and the engine has thus not decelerated enough that it will need as much time to get back up to speed, the delay in purging will be less.
