Abstract
The utility model discloses an engine decoration cover with an air inlet resonant cavity. The integrated air inlet resonant cavity is arranged under one side of the engine decoration cover, and a port of the resonant cavity extends out the outer side of the engine decoration cover to be connected with an air outlet pipe of an air filter. The resonant cavity of an air inlet system is integrated on the engine decoration cover so as to eliminate air inlet thunder, not affect distribution of an engine cabinet and guarantee cleanness and attractiveness of the engine cabinet.
Description
Technical field
The utility model relates to engine decorative cover and engine aspirating system resonant cavity.
Background technique
Along with automobile popularizing at home; Client is more and more fastidious to the NVH performance of automobile; And gas handling system is as one of main noise source of automobile; The reduction inlet noise improves air inlet sound quality simultaneously and just seems particularly important, therefore likes that gas handling system is designed with various silencer elements, like resonant cavity, quarter-wave long tube etc.But when increasing silencer element, will guarantee the very difficulty that neatly totally just becomes of engine compartment, this is a contradiction.
Summary of the invention
The purpose of the utility model provides the engine decorative cover of bringing the gas resonant cavity into of the neat and artistic and band noise elimination effect of a kind of outward appearance.
The described engine decorative cover of bringing the gas resonant cavity into of the utility model, its side-lower at the engine decorative cover has integrated air inlet resonant cavity, and the interface of air inlet resonant cavity stretches out in the engine decorative cover outside, connects empty filter steam outlet pipe.
In addition, engine decorative covers on motor and is provided with support rubber cushion in the edge of one side relatively.
The place that this engine decorative cover is different from other engine decorative covers be the engine decorative cover integrated the gas handling system resonant cavity; This design is mainly increases the 83Hz sound deadening capacity; Corresponding car load 2500rpm air inlet is thundered; Through dexterously resonant cavity and engine decorative cover being combined, not only eliminated the layout that air inlet is thundered but also do not influenced engine compartment, guaranteed the neat and artistic of engine compartment.
Description of drawings
Fig. 1 is the axonometric drawing of the engine decorative cover of band resonant cavity.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
The utility model is made up of interface 6 of empty filter steam outlet pipe 1, air inlet resonant cavity 2, empty filter steam outlet pipe decoupling zero ripple 3 and 7, engine decorative cover 4, engine decorative cover support rubber cushion 5, resonant cavity 2 and empty filter steam outlet pipe 1 etc.
The engine decorative cover of band resonant cavity shown in Figure 1; It has integrated air inlet resonant cavity 2 at the side-lower at engine decorative cover 4; I.e. integrated gas handling system resonant cavity on the engine decorative cover; The interface 6 of air inlet resonant cavity 2 stretches out in engine decorative cover 4 outsides, through the empty filter steam outlet pipe 1 of clip connected, on the empty filter steam outlet pipe decoupling zero ripple 3 and 7 is arranged; The effect of decoupling zero ripple 3 is to reduce the influence of engine air throttle place vibration to the resonant cavity vibration, and the effect of decoupling zero ripple 7 is to reduce the influence of engine luggine to empty filter vibration.In addition, engine decorative covers on motor and is provided with support rubber cushion 5 in the edge of one side relatively, and the effect of support rubber cushion 5 is to reduce the influence of engine luggine to resonant cavity.
The outstanding feature of the utility model is that the air inlet resonant cavity is integrated in the engine decorative cover, and the 2500rpm air inlet is thundered in the elimination car when the assurance engine compartment is totally attractive in appearance.
