Abstract
A canister purge system for throttleless internal combustion engine intake systems includes a plurality of purge ports, each of which is adapted for connection to an intake port of an internal combustion engine. An evaporative emissions canister is in fluid connection with each purge port. Each purge port includes a valve responsive to pressure changes in the intake port and permitting vapor flow from the evaporative emissions canister into the intake port when a vacuum condition is present in the intake port. The valves prevent flow from the intake port to the evaporative emissions canister when a vacuum is not present in the intake port.
