Description

Connecting pipe between cylinder head of motorcycle engine and carburetor

technical field

The utility model relates to a component on a motorcycle, in particular to a connection structure between a motorcycle engine cylinder head and a carburetor.

Background technique

The motorcycle engine cylinder head is connected to the carburetor through the joint, and the atomized fuel mixed with the fuel and air is sent to the combustion chamber in the cylinder head through the carburetor for combustion, but the atomized fuel installed on the existing joint is too The air passage is only to connect the carburetor with the combustion chamber of the cylinder head, and introduce the atomized fuel of the carburetor into the combustion chamber. If the fuel and air in the carburetor are not mixed sufficiently, it will increase fuel consumption and affect the performance of the engine. Combustion efficiency reduces the power of the engine and fails to meet the exhaust emission requirements.

Utility model content

In order to solve the above problems, the purpose of this utility model is to provide a simple structure connecting pipe between the cylinder head of the motorcycle engine and the carburetor, which can fully mix the fuel oil after the carburetor is atomized, and improve the combustion efficiency of the engine , so as to increase the power of the engine and reduce fuel consumption, so that the exhaust emissions can meet the requirements.

In order to achieve the above purpose, the utility model adopts the following technical scheme: it includes a pipe body, a first flange and a second flange, the pipe body is provided with a through hole of the pipe body, and the first flange is fixed to one end of the pipe body. As a whole, the second flange is solidly integrated with the other end of the pipe body, and at least two evenly arranged guide vanes are arranged in the through hole of the pipe body, and the guide vanes are formed in the through hole of the pipe body by The end of the second flange extends in an arc shape toward the end of the first flange, and the end surface of the first flange is parallel to the end surface of the second flange.

When in use, the first flange on the pipe body is connected to the pipe body head connected to the atomized fuel inlet of the cylinder head, and the second flange on the pipe body is connected to the atomized fuel outlet of the carburetor. The through hole in the tube body and the tube head on the cylinder head transmit the atomized fuel from the carburetor to the combustion chamber of the cylinder head. The guide vanes in the through holes of the pipe body will force the atomized fuel to rotate, so that the atomized fuel can be remixed, and rotate at a higher speed into the engine combustion chamber, resulting in a siphon effect and boosting, increasing the amount of atomized fuel entering , The swirling airflow can more fully mix oil and gas, significantly improving the combustion efficiency of the engine, thereby increasing the power of the engine and reducing fuel consumption, so that the exhaust emission can meet the requirements. The guide vane has a certain arc length in the through hole of the pipe body, which increases the rotation distance of the atomized fuel, makes the remixing of the atomized fuel more complete and further increases the fuel entering the combustion chamber. Significantly improve the combustion efficiency of the engine, improve the power of the engine, and reduce the fuel consumption.

Due to the adoption of the above-mentioned technical scheme, the utility model has a simple structure, which can make the fuel oil fully mixed again after the carburetor is atomized, which obviously improves the combustion efficiency of the engine, thereby increasing the power of the engine and reducing the consumption of fuel. Make exhaust emissions meet the requirements.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

As shown in Figures 1-5, the utility model includes a pipe body 1, a first flange 2 and a second flange 3, the pipe body 1 is provided with a pipe body through hole 4, the first flange 2 and the pipe One end of the body 1 is solidly integrated, and the second flange 3 is solidly integrated with the other end of the pipe body 1. It is characterized in that at least two evenly arranged guides are arranged in the through hole 4 of the pipe body 1. The flow vane 5 and the guide vane 5 extend in an arc shape from the second flange end to the first flange end in the through hole 4 of the pipe body.

When in use, the first flange on the pipe body is connected to the pipe body head connected to the atomized fuel inlet of the cylinder head, and the second flange on the pipe body is connected to the atomized fuel outlet of the carburetor. The through hole in the tube body and the tube head on the cylinder head transmit the atomized fuel from the carburetor to the combustion chamber of the cylinder head. The guide vanes in the through holes of the pipe body will force the atomized fuel to rotate, so that the atomized fuel can be remixed, and rotate at a higher speed into the engine combustion chamber, resulting in a siphon effect and boosting, increasing the amount of atomized fuel entering , The swirling airflow can more fully mix oil and gas, significantly improving the combustion efficiency of the engine, thereby increasing the power of the engine and reducing fuel consumption, so that the exhaust emission can meet the requirements. The guide vane has a certain arc length in the through hole of the pipe body, which increases the rotation distance of the atomized fuel, makes the remixing of the atomized fuel more complete and further increases the fuel entering the combustion chamber. Significantly improve the combustion efficiency of the engine, improve the power of the engine and significantly improve the fuel consumption, as shown in Figure 1, the end face of the first flange 2 is parallel to the end face of the second flange 3, which is convenient for the first flange 2 One flange is connected with the pipe head on the cylinder head of the engine, and the second flange is connected with the atomized fuel outlet of the carburetor, so that the connection is convenient.

As shown in FIGS. 2 , 4 , and 5 , each guide vane 5 moves closer to the center of the through hole 4 of the pipe body. This structure makes the gap between the guide vanes smaller, so that the guide vanes can produce the best guide effect on the atomized fuel.

As shown in FIG. 4 , there are two guide vanes 5 . As shown in FIG. 2 , there are three guide vanes 5 . As shown in FIG. 5 , there are four guide vanes 5 . The number of guide vanes can be set according to needs, so that the power of the engine can be improved to the greatest extent.

The above descriptions are only preferred implementations of the present utility model, and the scope of protection of the present utility model is not limited to the above-mentioned implementations. All technical solutions belonging to the principle of the utility model belong to the protection scope of the utility model. For those skilled in the art, some improvements made on the premise of not departing from the principle of the utility model, these improvements should also be regarded as the protection scope of the utility model.
