Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below in conjunction with attached drawing and specific implementation
The utility model is described in detail in example.
The utility model cannot achieve for the prior art and be evaporated under underload and two kinds of high load capacity different operating conditions
The problem of object is desorbed and whether the problem of being monitored can not be revealed to evaporant, a kind of two-way desorption pipeline and vapour are provided
Vehicle.
As shown in Figures 1 to 5, the utility model embodiment provides a kind of two-way desorption pipeline, comprising:
Venturi tube 10 and triple valve 20;
The first port 11 of the Venturi tube 10 is connect with the high pressure outlet air end of turbocharger, second port 12 with it is whole
The connection of vehicle air inlet pipeline, third port 13 are connect by the first pipeline 31 with the triple valve 20;
The first port 21 of the triple valve 20 is connect by the second pipeline 32 with the inlet manifold of engine, second port
22 connect with the third port 13 of the Venturi tube, and third port 23 is connect by third pipeline 33 with carbon tank valve, the carbon
The other end of pot valve connects canister.
