Description

EFI motorcycle carbon canister installation combination

technical field

The utility model belongs to components of motorcycles, in particular relates to a carbon tank installation combination of electric jet motorcycles.

Background technique

With the development of EFI motorcycle technology, it is necessary to install a carbon canister between the motorcycle fuel tank and the engine intake valve. The carbon canister absorbs the fuel vapor in the fuel tank, and then transmits the gasified oil particles to the engine to realize Recycling and utilization of fuel vapor in the fuel tank can reduce the pollutant discharge of motorcycles, so that the pollutant discharge of motorcycles can reach and exceed the national environmental protection standards.

As shown in Figures 1 and 2, the structure of the existing motorcycle is very compact, and the motorcycle frame belongs to a basic component of the motorcycle, wherein the rear suspension support tube is used as a part of the motorcycle frame, and the front end of the rear suspension support tube is connected to At the lower part of the front body of the frame, the rear end is connected to the rear body of the frame to stably connect the front body and the rear body of the motorcycle frame. Vehicle frame is as the main frame that constitutes motorcycle, and attachments such as engine, fuel tank are installed on this main frame again, but the vehicle body of existing motorcycle does not have the installation position of carbon canister.

The disadvantages of the prior art are: the existing motorcycle body has no installation position for the carbon tank, and cannot absorb the fuel vapor in the fuel tank, and the pollutant discharge amount of the motorcycle is difficult to meet the national environmental protection requirements.

Utility model content

The purpose of this utility model is to provide an EFI motorcycle carbon tank installation combination, which can install the carbon tank on the motorcycle body, absorb the fuel vapor in the fuel tank, and send it to the engine for effective use, so that the pollutant discharge amount of the motorcycle can reach National environmental requirements.

The technical scheme of the utility model is as follows: an EFI motorcycle carbon tank installation combination, including a rear suspension support tube, the front end of the rear suspension support tube is connected to the lower part of the front body of the frame, and the rear end of the rear suspension support tube is connected to On the rear body of the vehicle frame, the key is: the middle part of the rear suspension support tube is fixed with a carbon canister fixing lug, and a carbon canister is installed on the carbon canister fixing lug, and the adsorption port of the carbon canister is connected with the motorcycle fuel tank pipe The desorption port of the carbon tank communicates with the engine intake valve pipeline.

This structure is to install the carbon tank on the basis of maintaining the original structure of the motorcycle body, and the carbon tank realizes the effective adsorption and utilization of fuel vapor.

The carbon canister is provided with a hoop, and the hoop is connected to the fixed lug of the carbon canister through bolts.

The hoop surrounds the carbon canister, and the hoop is fixed on the fixing lug of the carbon canister, and the positioning of the carbon canister is realized by means of the hoop. The carbon canister is hung on the rear suspension support tube, so that the canister is close to the fuel tank and the engine, and the total length of the pipeline connecting the adsorption port of the carbon canister to the fuel tank, and the pipeline connecting the desorption port to the intake valve is minimized.

The carbon canister fixing lug is a strip block, one end of the carbon canister fixing lug is welded on the rear suspension support pipe, the other end of the carbon canister fixing lug has a carbon canister fixing hole, and the carbon canister fixing hole is The mounting bolts are connected with the hoop.

One end of the bar block is a flat end, which is convenient for welding with the rear suspension support pipe, and the other end is a circular arc end, which is convenient for opening the carbon tank fixing hole and connecting with the hoop and the carbon tank.

The remarkable effect of the utility model is: providing a kind of EFI motorcycle carbon tank installation combination, which can install the carbon tank on the basis of maintaining the original body structure of the motorcycle, so that the carbon tank is close to the fuel tank and close to the engine, saving The space resource of the motorcycle body, the carbon canister absorbs the fuel vapor in the fuel tank, and transports it to the engine for effective use, so that the pollutant discharge of the motorcycle meets the national environmental protection requirements.
