Description
Technical Field
The utility model relates to a double-cylinder synchronous engine of a motorcycle, in particular to an air inlet mechanism for the double-cylinder synchronous engine of the motorcycle.
Background
Electronic injection of motorcycles has become a development trend of the industry, and more motorcycle engines adopt an electronic injection technology. For example, the double-cylinder large-displacement motorcycle sold in the current market can better exert the performance of the engine by using the electronic injection technology. The air inlet mechanism of the motorcycle double-cylinder engine is a part for connecting the whole air filter and the cylinder body, so that the air filtered by the air filter enters the cylinder body through the air inlet mechanism, and the fuel oil sprayed by the fuel oil electronic injection system can be mixed with the air in the air inlet mechanism to form fuel oil mixed gas. The existing air inlet mechanism comprises a double-cavity valve body, two independent air inlet channels can be formed in the double-cavity valve body, a corresponding air inlet pressure temperature sensor and a corresponding throttle valve position sensor are arranged on the valve body for each cavity, an accelerator cable tray is arranged on the double-cavity valve body, and an oil injector is arranged at the outlet of each cavity of the double-cavity valve body, so that two air inlet channels for independently air inlet to two cylinders of an engine are formed, and mutual interference of air inlet of the two cylinders is avoided.
However, such an intake mechanism is complicated in structure, involves a large number of constituent parts, and results in high manufacturing costs of the entire intake mechanism. And the whole air inlet mechanism is large in size, and more factors need to be considered in the layout design of the whole automobile, so that the design and development of the whole automobile are not facilitated. Particularly in a double-cylinder synchronous engine of a motorcycle, the existing air inlet mechanism easily causes a plurality of restrictions on the space layout design of the engine, thereby easily influencing the space layout optimization of the whole motorcycle.
Disclosure of Invention
The utility model aims to provide an air inlet mechanism for a double-cylinder synchronous engine of a motorcycle, which aims to solve the problem that the air inlet mechanism in the prior art is easy to influence the spatial layout design of the engine due to complex structure and large volume.
In order to achieve the aim, the basic scheme of the utility model provides an air inlet mechanism for a double-cylinder synchronous engine of a motorcycle, which comprises a valve body, wherein a sensor is arranged on the valve body, and the valve body is a single-cavity valve body; the three-way type air inlet pipe is provided with an air inlet and two air outlets, and the air outlet end of the valve body is connected with the air inlet of the air inlet pipe through a connecting rubber sleeve.
The beneficial effect of this basic scheme lies in: by adopting the arrangement, the two cylinders of the double-cylinder synchronous engine share the single-cavity valve body through the three-way air inlet pipe, compared with the double-cavity valve body in the prior art, the structure of the valve body is simplified, the volume of the valve body is reduced, thereby reducing the assembly process, reducing the assembly error of an air inlet mechanism, simultaneously reducing the production and manufacturing cost of the valve body, improving the consistency of products and facilitating the overall space layout design of the double-cylinder synchronous engine of the motorcycle. The two cylinders of the double-cylinder synchronous engine are long in air inlet interval time (the air inlet stroke of the two cylinders is separated by 360 degrees of crankshaft rotation angle), and the air inlet of the two cylinders is not greatly influenced by sharing one single-cavity valve body, so that the engine can work normally.
Further, the sensor is a three-in-one sensor integrating intake air pressure monitoring, intake air temperature monitoring and throttle position monitoring. By adopting the arrangement, the number of the sensors is reduced, so that the number of the plugging positions for installing the sensors is reduced, the structure is further simplified, the volume of the air inlet mechanism is reduced, and the assembly, the processing and other operations are further facilitated.
Further, the air inlet pipe is provided with oil spray holes corresponding to the two air outlets one by one. By adopting the arrangement, the fuel sprayed out of the fuel spray hole can timely enter the cylinder body for combustion, and the combustion efficiency of the fuel is improved.
Further, an oil sprayer matched with the oil spraying hole is arranged on the air inlet pipe. By adopting the arrangement, the fuel injector can be arranged relatively far away from the valve body, so that the distribution of parts of the whole air inlet mechanism is more uniform and reasonable, and the space layout is convenient to set.

The valve body 1 is also provided with a sensor 3, and in this embodiment, the sensor 3 is a three-in-one sensor 3 integrating intake pressure monitoring, intake temperature monitoring and throttle position monitoring. The air outlet end of the valve body 1 is connected with a connecting rubber sleeve 4. The connecting rubber sleeve 4 is connected with a three-way air inlet pipe 5 with an air inlet and two air outlets, and the air outlet end of the valve body 1 is communicated with the air inlet of the air inlet pipe 5 through the connecting rubber sleeve 4. The air inlet pipe 5 is U-shaped as a whole, the air inlet is arranged in the middle, and the two air outlets are positioned at the end part of the air inlet pipe 5 far away from the connecting rubber sleeve 4. The air inlet pipe 5 is provided with oil spray holes corresponding to the two air outlets one by one. An oil injection bracket 6 is arranged on the air inlet pipe 5, and an oil injector 7 matched with the oil injection hole is arranged on the oil injection bracket 6.
The specific implementation process is as follows: during installation, the air inlet end of the single-cavity valve body 1 is connected with an air filter of the whole vehicle, and two air outlets of the air inlet pipe 5 are respectively connected with two cylinders of the engine, so that the two cylinders of the engine share the valve body 1 for air inlet.
