The engine air intake system has a simple and novel structure. Through the fixed arrangement of the wavelength pipe communicated with the engine air intake hose on the engine air intake hose, the purpose of reducing noise is achieved. The engine air intake system not only is up to relevant standards, but also can improve environment, and has the characteristics of convenience of use, integrity and attractiveness.
Description
Technical field
The utility model belongs to automobile technical field, specifically, relates to a kind of engine aspirating system.
Background technique
Motor needs a large amount of clean airs, thereby the air in the external world need be handled when work, so the component aggregate of air or mixed gas importing cylinder is called engine aspirating system.It is simple that the gas handling system of motor seems, often do not paid attention to by people, but in fact in the research of motor car engine, the noise of the gas handling system of motor is exactly a very big research topic, because the noise of gas handling system not only can influence the level of comfort that car load noise and occupant take, also can be the key factor that can noise emitted by accelerating motor vehicle reach relevant criterion simultaneously.Existing engine aspirating system is made of empty filter suction tude, empty filter and engine charge flexible pipe etc., wherein on the suction port of empty filter and air outlet, be connected to described empty filter suction tude and engine charge flexible pipe respectively, then the engine charge flexible pipe is linked to each other with motor, behind the automotive ignition, air can enter the sky filter via empty filter suction tude, enter the engine charge flexible pipe after filtering by empty filter again, enter the engine chamber burning at last.There is a significantly deficiency in the engine aspirating system of this kind structure, when that is exactly engine operation, because engine aspirating system is not provided with relevant muffler part, thereby enter in a large number in the process of motor at air, produce bigger noise, increase the car load noise, influenced environment simultaneously.
The model utility content
Technical problem to be solved in the utility model be to provide a kind of simple in structure, reliability is high, can reduce the engine aspirating system of automobile noise greatly.
The technical solution of the utility model is as follows: a kind of engine aspirating system, comprise the engine charge flexible pipe, this engine charge flexible pipe one end is empty filter interface, the other end is the motor interface, its main points are: be installed with the wavelength pipe that communicates with this engine charge flexible pipe on described engine charge flexible pipe, described wavelength pipe outer end sealing, and the length of this wavelength pipe be sound wave when in air, propagating wavelength 1/4th.
The utility model is big at conventional engines gas handling system noise, thereby creatively design on the basis that the noise etc. that influences car load is not enough, adopt above structure, sound wave enters the wavelength pipe from the engine charge flexible pipe, because wavelength pipe outer end sealing, sound wave can reflect back into the engine charge flexible pipe after at the bottom of sound wave arrives this wavelength pipe pipe, then be radiated outside, if this moment the wavelength pipe length setting be when propagating in the noise air of the frequency that is eliminated wavelength 1/4th, then the sound wave of this frequency just in time is crest and trough overlaid at the inner mouth of pipe place that enters the wavelength pipe with this frequency sound wave that reflects from the outer end pipe end, thereby the sound wave of this frequency is cut out, finally reach the purpose that the car load noise reduces.
As preferably: having the wavelength interface tube near on the described engine charge flexible pipe of described motor interface, described wavelength pipe the inner is stretched in this wavelength interface tube and is fixed on the described engine charge flexible pipe.Adopt above structure, the more close noise nidus of wavelength pipe, thereby largely with NR noise reduction.
As preferably: described wavelength pipe inner end outer wall is provided with the hoop flange, on the wavelength pipe outer wall between this hoop flange and the inner termination of described wavelength pipe, be provided with projection, described hoop flange and the projection all with the clamping of described wavelength interface tube, thereby the described wavelength pipe of described hoop flanged limits is moved vertically, make the described wavelength pipe of described projection restriction along circumferentially rotating.Adopt above structure, the purpose that hoop flange and projection are set all be for better with wavelength pipe location, so it is when the location of no axial and circumferential, the effective length of wavelength pipe changes easily, and rigging position also is difficult for determining, thereby makes that the effectiveness performance of this wavelength pipe is not good.
Beneficial effect: the utility model novelty simple in structure, adopt and on the engine charge flexible pipe, be installed with the wavelength pipe that communicates with this engine charge flexible pipe, thereby reach the purpose that reduces noise, both conform European standard also can be improved environment; Have characteristics such as easy to use, overall appearance.
