Description

Air cleaner and engine assembly
Technical field
The present invention relates to vehicular field, more particularly to a kind of air cleaner and engine assembly.
Background technology
With the continuous improvement of vehicle emission request, the application of hybrid vehicle is also more and more extensive, still, due to mixed Having closed the more conventional vehicle of power car more, one or more power sources, the engine nacelle space that result in hybrid electric vehicle are narrower It is small, improve the arrangement difficulty of each dynamical system so that enging cabin is crowded, unsightly.Also, due to engine nacelle Space limits, and can also sacrifice the parts relatively to be taken up space in some cabins, such as air cleaner.Air cleaner is mainly used in only Change the air for entering cylinder, the air that such as will not pass through filter is fed directly to engine, engine air will be caused 8 times of the abrasion increase of cylinder, 3 times of piston wear increase, 9 times of piston ring scuffing increase, the life-span of engine will reduce 2/3.
In tradition, generally reduce the volume of air cleaner, so that narrow and small start can be arranged in by obtaining air cleaner In machine cabin, but this cause air cleaner filter efficiency and engine needed for air inflow mismatch, engine charge System noise becomes big.In addition, narrow and small engine nacelle is also difficult to the silencer element that arrangement meets use demand, for example, for For common 4 cylinders and 6 Cylinder engines, it is necessary to the volume of silencer element reach 10L-15L, caused by engine aspirating system Noise is difficult to be effectively eliminated, and vehicle is difficult to obtain preferable NVH performances.
Thus, it is desirable to have a kind of air cleaner can overcome or at least mitigate the drawbacks described above of prior art.
The content of the invention
In view of this, the present invention is directed to propose a kind of air cleaner, is more suitable for for example mixing so as to obtain air cleaner Close the narrow and small engine nacelles such as power car cabin.

Further, along the width of the air cleaner, the filter core is arranged at the middle part of the accommodating chamber, and The accommodating chamber is divided into separate inlet chamber and outlet chamber, is respectively provided with the inlet chamber and the outlet chamber State porous plate.
Further, the porous plate of multiple different sizes is respectively arranged with the inlet chamber and the outlet chamber, Each porous plate is between the inwall of the accommodating chamber formed with resonator.
Further, the inlet chamber is formed as strip structure, and the length of the inlet chamber and/or width are 1/4 The odd-multiple of wavelength;And/or the outlet chamber is formed as strip structure, and the length of the outlet chamber and/or width are 1/4 The odd-multiple of wavelength.
Further, can be opened in the accommodating chamber formed with opening corresponding with the filter core, the filter core through described The accommodating chamber is extracted or be pushed into mouth out.
Further, the filter core includes nonwoven cloth material.
Further, the air cleaner includes upper shell and lower house, and the upper shell and the lower house enclose Into the accommodating chamber, along the short transverse of the air cleaner, the periphery of the filter core and the upper shell and the lower casing Body is tightly connected.
Further, formed with reinforcement structure on the upper shell and the lower house.
Further, the bottom of the air cleaner is provided with buffering fixing point.
Relative to prior art, air cleaner of the present invention has the advantage that:
The integrated function of having hood of air cleaner of the present invention, reduces air cleaner and hood institute The space of occupancy, rationally using narrow and small engine nacelle space, and it is arranged at porous in the accommodating chamber of air cleaner Plate and the inwall of accommodating chamber form resonator, by the collective effect of the resonator and filter core, can effectively cut down multi-frequency and make an uproar Sound, air cleaner frequency of noise elimination is greatly widened, without adding other silencer elements again on gas handling system pipeline, saved empty Between and improve the NVH performances of vehicle.
Another object of the present invention is to propose a kind of engine assembly, make it that it is for example mixed that the engine assembly is applied to Close the narrow and small engine nacelles such as power car cabin.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way:
A kind of engine assembly, the engine assembly include engine and are installed on the basis of the upside of the engine Air cleaner described above, the gas outlet of the air cleaner are connected with the air inlet of the engine.
The engine assembly is same relative to Dominant Facies possessed by prior art with above-mentioned air cleaner, herein no longer Repeat.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
