摘要:
A device for adjusting the degree of opening of the throttle valve of a carburetor comprising a cam pivotally mounted on a pivot. The cam is actuated by a wax valve and rotated in accordance with an increase in the temperature of the cooling water of the engine. The cam has a cam face which is engageable with a lever connected to the throttle valve for retaining the throttle valve at a predetermined fast idling degree during engine warm-up. An auxiliary lever is pivotally mounted on the pivot. The auxiliary lever has an outer circumferential face which is engageable with the lever of the throttle valve for retaining the throttle valve at the predetermined fast idling degree after completion of engine warm-up.

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.

According to the present invention, there is provided a fuel reserving device for reserving fuel therein comprising a wall for dividing an interior of the device to a fuel chamber and an air chamber, the wall being deformable according to the amount of the fuel in the fuel chamber, a discharge passage which is open to a space formed above the surface of the fuel in the fuel chamber and a shut off valve for normally shutting the discharge passage off. Gas is discharged from the space via the discharge passage when the shut off valve is open. The shut off valve is opened and the gas is discharged from the space when the amount of the gas is larger than a predetermined amount. On the other hand, the shut off valve is closed and the discharging operation of the gas is stopped when the amount of the gas is smaller than the predetermined amount.

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.

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 height control device for vehicle for maintaining constant a height from a wheel-side member to a body-side member of a vehicle, including expansive operation means provided on the wheel-side member to support the body-side member and adapted to be expanded and contracted in a direction of the vehicle height by supplying and discharging an operating fluid with respect thereto; link means provided between the wheel-side member and the body-side member to connect each other and adapted to be operated in response to a change in the height between the wheel-side member and the body-side member; control means connected to an operation output portion of the link means to control supply, discharge and stop of the operating fluid with respect to the expansive operation means in response to the operation of the link means; damper means provided at the operation output portion of the link means to damp a relatively short fluctuating operation of the link means to restrict a responsive operation of the control means and to allow a relatively long ordinary operation of the link means to responsively operate the control means; and elastic means provided at a portion of the link means on the side of the wheel-side member away from the operation output portion connected to the control means to elastically absorb and accumulate an operating force of the link means to ordinarily operate the link means. In such a mechanical height control device for vehicle, a vehicle height can be maintained constant irrespective of a change in load on the vehicle, and the operation of the control means is suppressed in response to high-frequency vibration during running of the vehicle.

In a variable venturi type carburetor having a slow speed system, a fuel vapor conduit is provided, an inlet of which is open to a main fuel passage, an outlet of which is open to an intake passage. Fuel vapor occurring in the main fuel passage is carried through the fuel vapor conduit, so as not to be introduced into a slow fuel passage; thereby, the engine is rotated stably with a relatively lean air-fuel ratio.
摘要:
A variable venturi-type carburetor comprising a vacuum chamber and an atmospheric pressure chamber which are separated by a suction piston. A needle is mounted on the central portion of the tip face of the suction piston. A suction hole, interconnecting the vacuum chamber to a venturi portion of the carburetor, is formed on the tip face of the suction piston at a position located upstream of the needle. The vacuum chamber is open to the atmosphere via a flow rate control valve apparatus when the engine temperature is low. The vacuum chamber is disconnected from the atmosphere by the flow rate control valve apparatus when the engine temperature is high.
