ABSTRACT:
A fuel vapor surge system includes a fuel tank, an intake passage, a fuel vapor storage canister in the fluid communication with the fuel tank, a vapor purge passage in fluid communication with the intake passage and the fuel vapor storage canister, and a closing member movably mounted in the intake passage. The closing member has a first position where the closing member blocks fluid communication between the intake passage and the vapor purge passage and is outside of a fluid stream of the intake passage when fluid is flowing through the intake passage and a second position where the closing member opens fluid communication between the intake passage and the vapor purge passage and extends into the fluid stream of the intake passage when fluid is flowing through the intake passage.
