    摘要: Pressure detection means detects the pressure of an evaporation purge system that includes a fuel tank and a communicating tube, which connects a canister for adsorbing and retaining fuel vapor to an intake pipe. Shutout means shuts out the evaporation purge system from atmospheric air. A pump is driven for pressurization or depressurization purposes while the shutout means shuts out the evaporation purge system from atmospheric air. The pump is stopped when the pressure detected by the pressure detection means reaches a predetermined level. A leak judgment is formulated in accordance with pump drive time and a pressure change after pump stoppage.

    摘要: In a fuel controller which comprises; a venturi portion formed in an air-intake path adapted to feed air to an internal combustion engine; a throttle valve installed on the downstream side of the venturi portion; an auxiliary throttle valve and a fuel injection portion provided between the throttle valve and the venturi portion; a bypass air path opened at the venturi portion and at the upstream side thereof; a hot-wire type air flow sensor provided in the bypass air path for detecting an amount of air passing therethrough; and a proportional electromagnetic device which controls the amount of air passing through the bypass air path at a constant level with an air needle valve provided therein and which controls an amount of fuel passing through a fuel path corresponding to an amount of air passing through the air-intake path with a fuel needle valve provided in the fuel path communicating with the fuel injection portion, the auxiliary throttle valve and the throttle valve are operated interlockedly through a link mechanism.
