Title: Leak diagnostic device for evaporative fuel treatment system
Inventor: OKUMA SHIGEO
IPC: F02M25/08
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To ensure leak diagnosis by removing residual pressure and residual gas from an evaporative fuel pipe reliably, and shorten the time for the scavenging. SOLUTION: Prior to a leak diagnosis, an electric pump 28 forces air into an evaporative fuel pipe to remove residual pressure and residual gas therefrom. This scavenging time is set longer as the temperature of fuel detected by a fuel temperature sensor 35 is higher. After this scavenging, air is fed by way of a reference orifice 24 to be released to the atmosphere, during which based on the driving current of the electric pump 28 a determination level is set. Air is then fed to bypass the reference orifice 24, during which any driving current (driving load) of the electric pump 28 equal to or lower than the determination level leads to a diagnostic detection of a leak.
