摘要：A vaporized fuel processing device includes a discharging passage having acanister and connected to a fuel tank, the discharging passage being provided with a stopvalve and a relief valve that is opened when the pressure in a fuel tank is out of a first
pressure range. A vaporized fuel processing device performs a purge flow detectionprocess when the pressure in the fuel tank is within a second pressure range included inthe first pressure range. On the other hand, the vaporized fuel processing device opensthe stop valve when a purge is being performed, the frequency of performing the purgeflow detection process is small, and the pressure in the fuel tank is out of the secondpressure range.
