Problems solved by technology

However, when the pressure in the intake pipe is positive, the vaporized fuel in the canister cannot be sucked in, and even the intake air flows back from the intake pipe to the canister, so it is not ideal.

Embodiment Construction

[0048] Hereinafter, the form for implementing this invention is demonstrated using drawing.

[0049] [Overall structure of the engine control system 1 including the evaporative fuel device ( figure 1 )]

[0050] figure 1 An example of the overall configuration of the engine control system of a vehicle is shown. In addition, in the description of this embodiment, as an example of an internal combustion engine, a supercharger (in figure 1 In this example, a gasoline engine with a turbocharger) will be described as an example.

[0051] Such as figure 1 As shown, the engine control system 1 is controlled by the control unit 40, which is arranged in sequence from the intake side to the exhaust side with an air filter 10, an intake passage 21, a compressor 11, an intake passage 22, and an intercooler. 12. Intake passage 23, throttle valve 13, intake passage 24 (stabilizer box), intake manifold 25, combustion chamber 26, exhaust manifold 27, exhaust passage 28, turbine 14, e...

Abstract

The present invention provides an evaporated fuel supply device. A purge valve is arranged on the adsorption tank side in a purge passage. A check valve is arranged in an intake passage. Even the partial negative pressure residual exists in the purge passage between the purge valve and the check valve, the evaporated fuel in the adsorption tank is adsorbed to an internal combustion engine so as to control the change of an air-fuel ratio through fewer components during the burning purge control process. A controller regulates the purge valve open with a first opening degree or a first duty ratio during a purge operation. The controller may also regulate the purge valve to open with a second opening degree larger than the first opening degree or a second duty ratio larger than the first duty ratio a predetermined time after initiating the purge operation.

Description

technical field [0001] The present invention relates to an evaporated fuel supply device for supplying evaporated fuel stored in a canister to an internal combustion engine through an intake pipe. Background technique [0002] Conventionally, for example, in a vehicle equipped with an internal combustion engine, evaporated fuel generated in a fuel tank or the like is temporarily stored (adsorbed) in a canister. Furthermore, during operation of the internal combustion engine (during operation satisfying a predetermined condition), purge control is performed to suck the evaporated fuel in the canister through the intake pipe while introducing atmospheric air into the canister. Attracted to the internal combustion engine causing it to burn. Furthermore, by performing this purge control, the evaporated fuel in the canister is combusted without being released into the atmosphere, thereby reducing the impact on the global environment. [0003] For example, in the case of a vehic...
