ABSTRACT:
A self-diagnosable fuel-purging system used for a fuel processing system causes a fuel to be introduced into a canister packed with an adsorbent, such as activated carbon, onto which the introduced fuel is adsorbed, and causes the adsorbed fuel to be introduced into an engine when a negative pressure greater than a predetermined value is produced in an intake manifold upstream of a throttle valve. The fuel-purging system includes discriminating means for determining whether or not the fuel-purging system itself is normal on the basis of output signals representative of an air/fuel ratio in an exhaust gas from the engine and a temperature in the canister. The discriminating means determines abnormality of the fuel-purging system when both of the temperature in the canister and the air/fuel ratio are substantially constant while a fuel-purging condition, in which the fuel adsorbed onto the adsorbent in the canister is supplied to the engine, is detected.
