ABSTRACT:
A determination is made as to whether or not a fuel tank for an engine or the like is being replenished with fuel. The temperature of the fuel in the fuel tank is detected, and if the fuel temperature is dropping a determination of fuel tank replenishment is arrived at. Desirably, it is determined that the fuel tank is being replenished, if fuel temperature dropping has occurred for a predetermined number of times over a predetermined time period. Further, by using such a detecting device in a breakdown diagnosis device for an evaporated fuel processing mechanism which diagnoses whether or not fuel leakage is taking place in a predetermined section of a flow path from the fuel tank to an intake passage of an automobile engine erroneous diagnosis is prevented by preventing diagnosis during fuel tank replenishment.
