Title: Fault diagnostic device for evaporative fuel processing device and computer program therefor
Inventor: SHIGIHAMA SHINGO
IPC: F02M25/08
Filed: 2001-06-04
Abstract: PROBLEM TO BE SOLVED: To avoid at most, diagnosis of a small leakage fault and thereby restrain deviation of an air fuel ratio accompanied by fault diagnosis or secure an evaporative fuel supply performance frequency. SOLUTION: After a purge valve 35 is opened and decompression is performed in an evaporative fuel processing system, the purge valve 35 is closed in order to seal the evaporative fuel processing system. The leakage fault in the evaporative fuel processing system is diagnosed based on pressure variation in the evaporative fuel processing system detected at sealing. A large leakage fault is diagnosed by a first diagnosis means, and a small leakage fault is diagnosed by a second diagnosis means. When the pressure variation in the evaporative fuel processing system detected at diagnosis by the first diagnosis means for diagnosing the large leakage fault is smaller than a determination value of the second diagnosis means for diagnosing the small leakage fault, it is regarded as normal without performing diagnosis by the second diagnosis means.  After that, the diagnosis by the second diagnosis means is cancelled when a diagnosis result of the second diagnosis means is diagnosed as normal at the performance of the first diagnosis means even when a second diagnosis performance condition of the second diagnosis means is met.
