  "textContent": "An evaporative-emission-control system, including: a canister recovering an evaporated fuel generated in a fuel tank; an ambient-air-introduction passage introducing an ambient air into the canister; first and second purge passages purging a gas from the canister into the engine; first and second opening/closing valves configured to switch between a closed position and an open position; an engine-information-acquisition device acquiring an engine speed of the engine and/or a throttle-valve-opening degree; a purge-amount-calculation device configured to determine whether the first and second opening/closing valves are each in the open or closed position; and a valve control device controlling opening and closing of the first and second opening/closing valves. The purge-amount-calculation device selects a mode among a recovery mode, a first purge mode, a second purge mode, and a third purge mode. The valve control device controls the opening and closing of the first and second opening/closing valves based on the selected mode.",
