Abstract
The utility model relates to a noise reducing cylinder head cover for an engine, which is characterized in that double layer steel plates are overlapped and punched to form the cylinder head cover. An engine adopting the utility model is compared with the original engine with the structure which single layer steel plate materials are punched to form, the engine noise is reduced by about 1 dB. The utility model has the advantages of good noise reducing effect, simple structure and strong practicability.
Description
Technical field
The utility model relates to the seal arrangement of combustion engine, and particularly a kind of motor noise reduction cylinder head cover is the improvement of prior art, is applicable to the motor car engine use.
Background technique
Development along with Domestic Automotive Industry, the concerned countries rules obtain further perfect, Economy, travelling comfort and the environmental pollution of automobile (discharging, noise) etc. have been proposed requirements at the higher level, simultaneously, the client also proposes similar requirement to this, automobile and prime mover industry have been proposed new problem.The available engine cylinder head cover, owing to adopt individual layer stamped steel plate structure, its noise reduction is undesirable, using effect is relatively poor, does not satisfy the development need of automobile, prime mover industry.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned deficiency of the prior art, provides a kind of and can effectively reduce the motor noise reduction cylinder head cover that engine noise pollutes.
Content of the present utility model is: a kind of motor noise reduction cylinder head cover is characterized in that: this cylinder head cover is the overlapping stamping forming cylinder head cover of double-layer plate (1), and other shape, structure are equal to prior art.
Compared with prior art, the utility model cylinder head cover adopts double-layer plate material impact briquetting structure, after being assemblied on the motor, the more former employing individual layer of engine noise steel plate materials impact briquetting structure reduces about 1dB, engine noise effectively reduces, excellent noise reduction effect, simple in structure, practical.
Description of drawings
Fig. 1 is the cross-sectional TV structure schematic representation of the utility model embodiment;
Fig. 2 is the utility model embodiment user mode structural representation.
Among the figure: 1-cylinder head cover, 2-cylinder head.
Embodiment
Referring to each accompanying drawing.A kind of motor noise reduction cylinder head cover, this cylinder head cover are that other shape, structure are equal to prior art by the overlapping stamping forming cylinder head cover 1 of double-layer plate; During use, cylinder head cover 1 is connected with cylinder head 2, the same prior art of Placement.After adopting this cylinder head cover 1, can effectively reduce engine noise 1dB.
