Abstract: An abnormality diagnosis apparatus for performing a leak check of an evaporative fuel processing system which includes a fuel tank, a canister for storing evaporative fuel generated in the fuel tank, a purging passage for connecting the canister to an intake system of an internal combustion engine, and a purge control valve provided in the purging passage. A process of reducing the pressure in the evaporative fuel processing system is executed with a limited flow rate of gases passing through the purge control valve when performing the leak check in an idling condition of the engine. The limited flow rate is set to a value equal to or smaller than a predetermined flow rate which is smaller than the maximum flow rate applied to the leak check performed in operating conditions other than the idling condition. The leak check is performed on the basis of a change in the pressure in the evaporative fuel processing system after the pressure reduction process.

Abstract: In a suction filter, a synthetic resin upper plate 4 to be connected to a fuel inlet pipe is integrally molded with an upper filtering fabric 2, and a synthetic resin lower plate 5 is integrally molded with a lower filtering fabric. Two end portions of a spring are fixed to the upper and lower plates, and the peripheral portions of the upper and lower filtering fabrics are bonded together to obtain a filtering fabric bag. Thus, there is no such risk that the filtering fabric bag comes off the inlet pipe, the filtering fabric bag is worn out, and creases and poor bonding occur. Thus, the suction filter can be obtained with high reliability and good productivity.

A monitoring apparatus for monitoring a fuel feed system of an internal combustion engine is provided with an A/F ratio detector and an A/F ratio controller for performing feedback control of the A/F ratio. An A/F ratio feedback coefficient is calculated according to the output of the detector. A malfunction determination parameter is calculated based on the coefficient. A purging is suspended when the parameter reaches a first decision value. The monitoring is suspended when the parameter reaches a second decision value in a purge cutting state. A value of the malfunction determination parameter it would take if the purge cut was not carried out is estimated using the value when the parameter reached the first decision value. The monitoring is resumed when the estimated value of the malfunction determination parameter reaches the second decision value.
