[0008] If the carbon canister 17 is directly connected to the suction passage 4 through the negative pressure pipe 19, the larger suction negative pressure in the suction passage 4 acts on the carbon canister 17, and under the action of the large suction negative pressure, a large amount of fresh Air is introduced into the carbon canister 17, causing the evaporated fuel adsorbed on the activated carbon in the carbon canister 17 to be easily detached. If a large amount of evaporated fuel is sucked into the intake system, the air-fuel ratio of the mixture will change, resulting in unstable combustion. Therefore, it is necessary to stably introduce evaporated fuel into the internal combustion engine while suppressing the influence of the negative suction pressure on combustion.

The invention provides a processing device (50) of evaporated fuel for an automatic tumbrel capable for effectively absorbing evaporated fuel, reducing deviation of pressure change and pressure distribution in a suction access to deal with the evaporated fuel stably. The invention is provided with a fuel tank (26) for supplying fuel to a carburetor (46) connected with an engine (22). The evaporated fuel evaporated from the fuel tank (26) is stored in one end of a carbon tank (92) through a discharge pipe (91). Using suction subpressure, when the evaporated fuel is supplied to the suction system of the engine (22) from the carbon tank (92) through a purification piping (98), supply volume of evaporated fuel is controlled by a purification control valve (94) arranged in the midway of the purification piping (98), wherein the purification piping (98) is connected with the body of a carburetor (96), and the body of the carburetor (96) contains a piston valve (122) arranged in the carburetor (46).
Description
technical field [0001] The present invention relates to an improvement of an evaporated fuel processing device for motorcycles. Background technique [0002] In a vehicle equipped with an engine such as a motorcycle, the fuel evaporates in a fuel tank storing fuel supplied to the engine to generate gaseous evaporated fuel. Because the composition of the evaporated fuel is HC (hydrocarbons), it is sucked into the engine by using the evaporated fuel treatment device to absorb it at one end of the carbon canister connected to the fuel tank, and use the suction negative pressure of the engine's suction system internal combustion to prevent its release into the atmosphere. [0003] As a conventional evaporated fuel processing device, it is known that the evaporated fuel stored in the canister is sucked into the internal combustion engine together with the air-fuel mixture by connecting the canister to an intake passage provided in the internal combustion engine. (For example, r...
