Detailed Description

The utility model is described in detail below with reference to the figures and specific embodiments.

Example (b):

as shown in figures 2 and 3, an automobile-used carbon canister supporting structure, strain support 2 including OBD module support 1 and ash, OBD module support 1 strains support 2 with the ash and all installs on carbon canister casing 3, and fixed mounting has OBD module 4 on the OBD module support 1, and ash strains fixed mounting has the ash to strain 5 on the support 2, and ash is strained and is provided with connecting line 6 between support 2 and the OBD module support 1.

Wherein, OBD module support 1 is close to canister body 7, and ash is strained support 2 and is close to canister fixed point 8, and OBD module support 1 leads to the atmosphere mouth with the canister and is connected, and OBD module support 1 leads to the position that the atmosphere mouth is connected with the canister and is provided with sealing washer 9, and connecting tube 6 also is provided with sealing washer 9 with the position that OBD module support 1 is connected, and in this embodiment, O type sealing washer is chooseed for use to sealing washer 9.

The connecting pipeline 6 is of an inverted U-shaped structure, one end of the connecting pipeline 6 is communicated with the ash filter 5, and the other end of the connecting pipeline 6 is communicated with the OBD module 4.

In addition, in order to further improve the integration degree of the utility model and adapt to the installation requirements of different vehicle types (for example, the vehicle type in eastern and European regions of Europe does not have a fuel oil evaporation system leakage diagnosis requirement, an OBD module can be not equipped for the vehicle type in the eastern and European regions of export, but an ash filter also needs to be equipped for protecting a carbon canister from being blocked by dust and influencing the ventilation performance), the utility model arranges an ash filter shell for installing an ash filter 5 on the OBD module support 1, namely, the OBD module support 1 can simultaneously support the installation and fixation of the ash filter.
