摘要： A fuel supply control device including a purge control valve. The maximum purge rate, that is, the ratio between the amount of purge and the amount of intake air when the purge control valve is fully open, is stored in advance. The purge control valve is controlled in its duty ratio, which duty ratio is the target purge rate/maximum purge rate. When the purge is started, the target duty ratio is gradually increased. When the purge is performed and the feedback correction coefficient FAF falls, the feedback correction coefficient FAF is gradually returned to the FAF before the start of a purge, the purge A/F correction coefficient is increased, and the amount of injection is corrected by the sum of the purge A/F correction coefficient and the feedback correction coefficient.

摘要： A malfunction detection apparatus for detecting a malfunction in an evaporative fuel purge system, which malfunction detection apparatus is able to suppress a fluctuation of an air-fuel ratio. A negative pressure inside an intake passage is introduced into the evaporative fuel purge system. The existence/nonexistence of a malfunction in the evaporative fuel purge system is determined by using pressure values inside the evaporative fuel purge system which values are detected and supplied by a pressure detecting unit. The apparatus is provided with an air-fuel ratio fluctuation suppressing unit for suppressing a fluctuation of the air-fuel ratio of air suctioned into an engine when introducing the negative pressure into the evaporative fuel purge system.

摘要： A pressure control device allows evaporated fuel evaporated in an fuel tank of an engine to be discharged to a canister during the engine running state. The canister absorbs the evaporated fuel. The pressure control device continues to allow evaporated fuel in the fuel tank to be discharged to the canister after the engine stops until a predetermined period has elapsed. The pressure control device allows evaporated fuel in the fuel tank to be discharged to the canister while a pressure in the fuel tank is higher than a first predetermined pressure after the predetermined period has elapsed in the engine stopped state. On the other hand, the pressure control device prevents evaporated fuel in the fuel tank from being discharged to the canister while a pressure in the fuel tank is lower than the first predetermined pressure after the predetermined period has elapsed in the engine stopped state.

摘要： A canister communicates with an intake manifold of an internal combustion engine through a purge pipe. The canister absorbs fuel vapor evaporated in a fuel tank. The absorbed fuel vapor is purged into the intake manifold when the engine is on. A gas leak check module communicates with the canister for drawing air by an air suction pump 43. When the engine is off, the air suction pump is driven and draws hydrocarbon floating at a vicinity of an intake port through the purge pipe. Thus, the hydrocarbon floating at the vicinity of the intake port is absorbed in the canister so that emission of hydrocarbon is reduced.
