Filed: 2003-05-29
Abstract: <P>PROBLEM TO BE SOLVED: To make it possible to diagnose a leak of an evaporating fuel processing apparatus with high precision without being affected by evaporating fuel.  <P>SOLUTION: A diagnostic target zone of the evaporating fuel processing apparatus is closed to diagnose the leak based on a pressure change when the closed zone is pressurized or depressurized. Then, when the pressure doesn't reach reference pressure within a predetermined period of time, it is judged that a leak hole with a diameter larger than a reference large diameter exists. On the contrary, when the pressure has reached the reference pressure, a curvature of a time change curve of the pressure and a threshold value depending on a remaining amount of the fuel are compared. When the curvature is larger than the threshold value, it is judged that the leak hole exists with a diameter smaller than the reference large diameter and larger than the reference small diameter, while when the curvature is smaller than the threshold value (the pressure changes at nearly constant rate), it is judged that no leak hole exists or that the leak hole with a diameter smaller than the reference small diameter permissible exists.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
