Problems solved by technology

[0006] However, in the above-mentioned prior art, the carbon tank is arranged in front of the engine and outside the downtube of the vehicle frame, so that the carbon tank will be cooled by the running wind generated by driving when the vehicle is running, thereby affecting the air in the carbon tank. The emission effect of evaporated fuel, and the temperature of the carbon tank will increase due to direct sunlight and other reasons when the vehicle stops, which will affect the absorption of evaporated fuel by the carbon tank

Abstract

To enable mounting of a canister on a vehicle body in a compact manner while favorably ensuring the charge performance and the purge performance of the canister in the arrangement structure of an evaporated fuel treatment device of a saddle-ride-type vehicle. An under cowl (26) is provided at a front side of a lower portion of an engine (14), and a canister (41) is arranged below the engine (14) and inside the under cowl (26).

Description

technical field [0001] The present invention relates to an arrangement structure of an evaporated fuel processing device which is equipped on a straddle vehicle such as a motorcycle and collects fuel gas evaporated in a fuel tank. Background technique [0002] Conventionally, it is known to install an evaporated fuel processing device (for example, a carbon canister) on a motorcycle (for example, refer to Patent Document 1). [0003] [Prior Art Literature] [0004] 【Patent Literature】 [0005] Patent Document 1: Japanese Utility Model Publication Publication No. 3-29573 [0006] However, in the above-mentioned prior art, the carbon tank is arranged in front of the engine and outside the downtube of the vehicle frame, so that the carbon tank will be cooled by the running wind generated by driving when the vehicle is running, thereby affecting the air in the carbon tank. The emission effect of evaporated fuel, and the temperature of the carbon tank will increase due to dire...
