<p>PROBLEM TO BE SOLVED: To suppress wasteful tank purge by appropriately finishing the tank purge.SOLUTION: In a vehicle where such tank purge can be executed that, when a pressure in a fuel tank 21 is not lower than a predetermined value P1, a sealing valve 33 and a purge valve 37 are opened in the state of operating an engine 10 for supplying fuel evaporative emission to the engine 10 while releasing it from the fuel tank 21 into an intake passage 11 until the pressure in the fuel tank 21 is lower than the predetermined value P1, an integrated valueΣV for the amount of fuel injected from a fuel injection valve 12 of the engine 10 during executing the tank purge is computed, and when the integrated valueΣV is not smaller than a second predetermined value V2, the tank purge is forcibly finished.</p> |
