    摘要： A fuel feed system which causes liquid fuel to evaporate so as to feed gaseous fuel, provided with an evaporator which includes a heater which heats the liquid fuel to vaporize it and an electric heater which adjusts the temperature of the heater. The heater has a heat conduction surface which supplies heat to the liquid fuel. A difference between the temperature of the heat conduction surface of the heater and the boiling point of the fuel at the evaporator is used as the basis to change the temperature of the heater and adjust the heat flux at the heat conduction surface.

    摘要： A forward flow region in which forward intake air currents are produced and a reverse flow region in which reverse intake air currents are produced are formed in the throttle bore of a throttle body 3 included in an internal-combustion engine, and the boundary between those regions extends below a throttle valve 5. A fuel vapor control system for an internal-combustion engine has a purge tube 13 joined to the throttle body 3 to supply fuel vapor into the throttle body 3 and is provided with an opening 22 which acts as a purge port. The opening 22 is positioned at a distance from the inner surface 21 of the throttle body 3 defining a throttle bore on the boundary between the forward intake air currents and the reverse intake air currents. Fuel vapor jetted through the opening 22 of the purge tube 13 into the throttle bore flows toward an intake manifold 2, diffusing into both the forward intake air currents and the reverse intake air currents from the boundary between the intake air currents. Accordingly, the fuel vapor is distributed evenly through the intake manifold 2 to the cylinders, so that increase in the difference in air-fuel ratio between the cylinders can be suppressed. The purge port can relatively easily be formed, because the purge tube 13 provided with the purge port is fitted closely in a bore formed in the throttle body 3.
