Problems solved by technology

However, when the performance of the PCSV is changed, the pulsation noise increases, and therefore, the deterioration of NVH characteristics may not be solved by a single pulsation chamber
Therefore, there is a further subsequent need to install additional pulsation chambers to account for changes in PCSV performance, and thus, an inevitable increase in size and cost

Abstract

A canister apparatus for a vehicle is provided. The apparatus reduces noise of a canister by utilizing an air gap disposed in the canister, and partition walls, which are disposed at predetermined positions in the air gap space in the canister. As a result, vehicle NVH characteristics are improved and the discharge amount of bleed emission that causes environmental pollution is reduced.

Description

technical field [0001] The present disclosure relates to a canister device for a vehicle, and more particularly, to a canister device for a vehicle that reduces noise of a canister using an air gap configured in the canister. Background technique [0002] Generally, a canister is a device for discharging air contained in vaporized fuel gas generated in a fuel tank into the atmosphere, and the canister is configured to collect fuel components and supply the fuel components to engine. Generally, a canister is installed in a vehicle in order to prevent the loss of fuel vaporized in the fuel tank and to prevent vaporized fuel from The gas is released into the atmosphere. [0003] attached figure 1 is a view showing the operation of a typical canister according to the related art. refer to figure 1 , a canister 3 for collecting vaporized fuel gas is installed between the fuel tank 1 and the engine 2, and a purge control solenoid valve (PCSV) 4 connected to the canister 3 is ...
