Abstract: PROBLEM TO BE SOLVED: To provide an evaporative fuel treatment device which can determine a block or a block degree of a purge line.SOLUTION: An evaporative fuel treatment device is employed to an engine for controlling an injection amount of an injector 25 so that an air-fuel ratio is maintained at a target value, and comprises an air-fuel ratio acquisition part 32 and a block determination part 35. The air-fuel ratio acquisition part 32 acquires an air-fuel ratio. The block determination part 35 determines a block of a purge line on the basis of a maximum variation amount Vm being a maximum value of an air-fuel ratio variation amount. In the engine which is controlled so as to maintain the air-fuel ratio at the target value, when the purge line is blocked, the air-fuel ratio is temporarily largely varied as a result of a slight delay of fuel injection amount control at the suction of fuel vapor at the valve-opening of a purge valve 15. On the other hand, when the purge line is completely or partially blocked, the fuel vapor is not sufficiently suctioned even if the purge valve 15 receives a valve-opening command, and the air-fuel ratio is not varied so much. The block of the purge line can be determined by using the air-fuel ratio variation.SELECTED DRAWING: Figure 2
