Description

Technical Field

[0001] The utility model relates to the technical field of carbon canister application, in particular to a carbon canister integrated with a CVS solenoid valve. Background Art

[0002] A carbon canister, a container filled with activated carbon, collects gasoline vapors for reuse and is a key component of the gasoline evaporative emission control (EVAP) system. The canister is typically installed between the gasoline tank and the engine. Because gasoline is a volatile liquid, the fuel tank is often filled with vapor at room temperature. The EVAP system directs the vapors into combustion and prevents them from escaping into the atmosphere.

[0003] Existing carbon canisters have a single structure and function, poor precision control of internal intake and exhaust, and are unable to condense and liquefy the treated steam for reflux. Therefore, to address the above problems, a carbon canister with an integrated CVS solenoid valve is proposed. Utility Model Content

[0004] The purpose of the present utility model is to provide a carbon canister with an integrated CVS solenoid valve in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions: a carbon canister with an integrated CVS solenoid valve, comprising a carbon canister body and a T-shaped cover provided with an integrated solenoid valve group, the output port and the input port located at the top of the carbon canister body are respectively sealed and fixedly connected to the two ports located at the bottom of the T-shaped cover, the integrated solenoid valve group is installed in a rectangular groove, a condenser is installed on one side of the top of the T-shaped cover, and the inlet end of the condenser is connected to the output control solenoid valve located in the integrated solenoid valve group through an output conduit, and a flow guide pipe part is distributed in the condenser.

[0006] Preferably, the input control solenoid valve of the integrated solenoid valve group is connected to an input conduit.

[0007] Preferably, the rectangular groove is opened in the middle of the surface of the T-shaped cover.

[0008] Preferably, sealing edge blocks are installed around the two ports at the bottom of the T-shaped cover.

[0009] Preferably, countersunk holes are provided at the bottom of both sides of the carbon canister body, and sealing bolts are installed in the internal threads of the countersunk holes.

[0010] Preferably, the condenser is filled with coolant.

[0011] Compared with the existing technology, the advantages of the utility model are: through the integration of the solenoid valve group, the supply and discharge can be precisely controlled, and the integrated solenoid valve group is placed in the rectangular groove on the T-shaped cover to reduce the external space occupied. The added condenser is used to liquefy the filtered vapor, which is conducive to reflux storage and use. A countersunk hole sealed by a sealing bolt is provided in the traditional carbon canister body to facilitate subsequent opening, cleaning and pouring out impurities inside the carbon canister.
