摘要： An apparatus for controlling a flow of evaporated fuel from a canister being fed into an intake passage of an engine through a plurality of control valves arranged in parallel in a purge passage between the canister and the intake passage. The plurality of control valves includes at least a first valve being switched on and off by setting a control factor indicating a duty ratio of an on-time within a duty cycle to a total duty-cycle time for the first valve, and a second valve being switched on and off by setting a control factor indicating an on-state or off-state of the second valve for a total duty-cycle time. The apparatus includes a first control part for setting a first control factor for the first valve so that the first valve is switched on at a rate indicated by the first control factor, and a second control part for setting a second control factor for the second valve so that the second valve is switched on and off at a timing different from a timing at which the first valve is switched on and off.

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 fuel vapor purge system connects a fuel tank with a canister and collects fuel vapor generated in the fuel tank by the canister. The purge system purges the collected fuel vapor to an intake passage of an internal combustion engine through a purge passage. A change of pressure due to fuel vapor generation in the fuel tank is measured while the purge passage is sealed. The pressure in the purge passage is differentiated from the pressure outside the purge passage and the purge passage is sealed. In this state, a change of the pressure in the purge passage is measured. After measuring the amount of generated fuel vapor, a test for leakage in the purge passage is performed based on the change of pressure due to the fuel vapor generation when measuring changes of pressure in the purge passage during a predetermined period.

摘要： A fuel-vapor emission-control system for an internal combustion engine which is capable of achieving both a reduction of the exhaust of vapor into the atmosphere and the prevention of an excessive increase in pressure within the fuel tank, regardless of the amount of internal pressure in the fuel tank, by providing on an atmospheric release port of the canister which adsorbs vapor adsorbed from the fuel tank of the internal combustion engine, thereby preventing release of the vapor into the atmosphere, an atmospheric release surface area changing valve which changes the surface area of an aperture to the atmosphere. The atmospheric release surface area valve operates to make the atmospheric release surface area larger when the internal pressure in the fuel tank is large than when the internal pressure in the fuel tank is small. The atmospheric release surface area changing valve can be configured as a mechanical type of pressure-sensitive valve which opens when the internal pressure in the canister exceeds a set value, and can also be configured as an electromagnetic valve, the degree of opening of which can be electrically varied in response to a detected value of vapor pressure within the system to thereby change the atmospheric release surface area.

摘要： A diagnostic apparatus for a fuel vapor treating apparatus closes a breather to shut a purge system valve during purge. While further continuing the purge, the apparatus detects the purge flow thereby caused and a pressure change occurring in the purge system. Based on the purge flow and the pressure change, the space volume in the purge system is estimated. By comparing the estimated space volume and the actual space volume in the purge system, the apparatus determines whether there is a failure or fault in the purge system.
