Title: Device for diagnosing failure of evaporator purging system
Inventor: MATSUOKA TAKUYA
IPC: F02M25/08
Filed: 2001-09-03
Abstract: PROBLEM TO BE SOLVED: To accurately diagnose a failure in a purging system by preventing an erroneous diagnosis. SOLUTION: Pressure rising speeds ΔP1, ΔP2 in the purging system composed of a canister 10, a fuel tank 11 and the like are measured by a pressure sensor 33 by keeping the system in negatively pressurized and hermetically sealed condition, and ΔP1, ΔP2 are compared with a prescribed determination map. Thereby, whether or not there is abnormality such as leakage or the like in the purging system is determined. When measuring an internal pressure rise, since a gas temperature in the fuel tank, which has once dropped by expansion when a pressure in the purging system has dropped, rises by heat exchange with the outside air through the wall surface of the tank, the internal pressure fluctuates, and an error is produced in the measured value of the internal pressure.  In order to prevent it, the measured value of the internal pressure rising speeds ΔP1, ΔP2 are corrected based on a difference between the temperature of the outside air and a temperature in the fuel tank. Thereby, a failure can be accurately diagnosed without being influenced by temperature fluctuation in the fuel tank.
