The beneficial effects of the utility model include: the intake pressure of the double-cylinder engine is stable, the power torque of the engine is favorably improved, and impact sound, gas friction sound and intake duct resonance noise generated by a gas distribution mechanism in an engine intake system can be eliminated.
Description
Technical Field
The utility model relates to a motorcycle air intake system field, concretely relates to but amortization and stable intake pipe of air pressure.
Background
With the development of large-displacement motorcycles and the use of multi-cylinder machines such as double cylinders and the like and an electric spraying system, the requirement on the stability of the air inflow of an air intake system is higher and higher. The air intake amount of each cylinder is required to be close to equal and sufficient to be close to the combustion power of each cylinder to be at a design theoretical value, and simultaneously, the decibel value of the intake noise is required to be reduced as much as possible.
Disclosure of Invention
To the weak point among the above-mentioned prior art, the utility model provides a but amortization and stabilize the intake pipe of entering atmospheric pressure, it can stabilize atmospheric pressure, promotes the power moment of torsion of engine, has good noise cancelling effect simultaneously.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a can amortize and stabilize intake pipe of atmospheric pressure which characterized in that: including last casing and lower casing of upper and lower lock connection, go up casing and casing constitution down and have the box-like structure of inner chamber, the one end of going up the casing is the inlet end has the air inlet that is used for connecting the air cleaner, the other end of going up the casing is the end of giving vent to anger has two interval distribution's gas outlet, the air inlet is followed the inlet end terminal surface extends outward and inclines left or right, two the gas outlet is followed the terminal surface of the end of giving vent to anger extends outward and the downward sloping.
Further, the gas outlet is sleeved with a connecting rubber pipe, and the connecting rubber pipe is fixedly connected to the gas outlet through a hoop.
Further, the inner diameter of the air inlet is larger than that of the air outlet, and the inner diameters of the two air outlets are equal.
The beneficial effects of the utility model include: the intake pressure of the double-cylinder engine is stable, the power torque of the engine is favorably improved, and impact sound, gas friction sound and intake duct resonance noise generated by a gas distribution mechanism in an engine intake system can be eliminated.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
An intake duct capable of muffling and stabilizing intake pressure as shown in fig. 1-2, characterized in that: including last casing 1 and lower casing 4 of upper and lower lock joint, go up casing 1 and lower casing 4 and constitute the box-like structure that has the interior cavity. One end of the upper casing 1 is an air inlet end having an air inlet 2 for connection to an air filter. The other end of the upper shell 1 is an air outlet end, and the air outlet end is provided with two air outlets 3 which are distributed at intervals. The inner diameter of the air inlet 2 is larger than that of the air outlets 3, and the inner diameters of the two air outlets 3 are equal. The air inlet 2 extends outwards from the end face of the air inlet end and inclines leftwards or rightwards, and the two air outlets 3 extend outwards from the end face of the air outlet end and incline downwards. The air outlet 3 is sleeved with a connecting rubber tube 5, and the connecting rubber tube 5 is also fixedly connected to the air outlet 3 through an anchor ear 6.
The utility model discloses an implement motorcycle that a certain brand's double-cylinder started, adopted this intake pipe, the air inlet end of this intake pipe is connected with the air cleaner, and the end of giving vent to anger is connected with the (air) intake valve body through connecting the rubber tube, and the (air) intake valve body sets up in the (air) intake valve department of engine. Stable intake pressure path: outside air enters the air inlet pipe cavity after being filtered by the motorcycle air filter, the air reduces the flow rate after expanding in the air inlet pipe cavity and forms stable pressure in the local part, then enters the air inlet valve body through the connecting rubber pipe to be metered and form gas tumble to be sucked into the engine to be combusted, and the power torque is favorably improved. Noise cancellation path: in the working process of the engine, the radiation of main sound sources such as impact noise, gas friction noise, air inlet channel resonance noise and the like generated by a valve mechanism is transmitted to an air inlet pipe through a throttle valve body, and sound waves are transmitted to the wall of a cavity body through an air outlet 3 pipeline and then are counteracted with incident sound waves to eliminate partial frequency band noise. Then enters the air filter from the air inlet 2 to eliminate partial frequency band noise and transmit the noise to the outside. The sound wave is eliminated twice, so that the intake noise elimination effect is obvious.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
