摘要： A failure detection system detects a failure occurring in an exhaust secondary air supply system of an internal combustion engine, and has a catalytic converter installed in an exhaust pipe of an exhaust system of the engine for reducing pollutants from exhaust gases emitted from the engine, a conduit connected, at one end, to the exhaust pipe at a location upstream of the catalytic converter and an air pump connected to an opposite end of the conduit for supplying compressed air in the conduit. The conduit is closed by the a valve which opens in response to the negative pressure and a second valve which opens in response to the conduit pressure. In the system a first prescribed level and the second prescribed level are set and two pressure switches are provided for generating output at the levels. A failure occurring in the air pump and the valve is detected based on operation of the air pump and the output of the pressure detectors. Alternatively, the failure is detected by changing the timing of the termination of the air pump and closing of the second valve while using one switch and the second prescribed level. The system is simple in configuration.

摘要： A component attaching hole 5 is opened in the tank main body 1 constructed by laminating an inner shell 3 and an outer shell 4 via a fuel permeation preventing layer 2, and the auxiliary component 6 is welded to the external surface of the tank main body 1 in such a manner as to cover the component attaching hole 5. The component attaching hole is formed so as to be tapered in such a manner that the component attaching hole gets wider toward the external surface of the tank main body 1, and a boss portion 9 is formed on the auxiliary component 6 which is tapered so as to fit in the component attaching hole 5, whereby a fuel permeation preventing layer 8 laminated on the internal surface of the auxiliary component 6 is made to extend over the external surface of the boss portion 9. When the tank main body 1 and the auxiliary component 6 are welded together, the fuel permeation preventing layer 8 on the external surface of the boss portion 9 is tightly joined to the fuel permeation preventing layer 2 exposed at the component attaching hole 5.

摘要： Disclosed herein is an evaporative emission control system which can prevent changes in fuel component in the fuel tank and vacuum boiling in the fuel pump to thereby accurately control the air-fuel ratio to a desired value and ensure smooth supply of the fuel. The control system includes an evaporative fuel passage for connecting a fuel tank and an intake system of an internal combustion engine, and a control valve is provided in the evaporative fuel passage for opening and closing the evaporative fuel passage. It is determined whether or not a fuel temperature is higher than or equal to a predetermined fuel temperature. If the fuel temperature is higher than or equal to the predetermined fuel temperature, the opening operation of the control valve is disabled.
