The invention relates to a method for improving a surface mode of an air filter or a resonator of an air inlet system of a car. The method comprises that at least one surface of the air filter or the resonator is produced into a curved surface. The invention also provides the air filter or the resonator of the air inlet system of a car engine. The air filter or the resonator comprises reinforcing ribs, wherein the at least one surface of the air filter or the resonator is the curved surface. By the aid of the method, under the conditions that the casing thickness of the air filter or the resonator, heights of the reinforcing ribs and thicknesses or quantity of the reinforcing ribs are not increased, the surface mode can be improved, so that the radiation noise level is improved, the cost is reduced to the maximum extent, and the process feasibility is improved. According to the air filter or the resonator obtained correspondingly, the surface mode is improved, and meanwhile, the weight is not increased greatly.
Description
technical field [0001] The invention relates to a method for improving the surface mode of an air filter (or "air filter" for short) and a resonator of an automobile engine air intake system, an air filter and a resonator, and the air filter and a resonator comprising the air filter and the resonator car engine intake system. Background technique [0002] The surface of the air filter and resonator of the traditional automobile engine intake system is flat, and its surface mode is low, which radiates noise. [0003] Traditionally, in order to increase the surface mode of the air filter or resonator, thereby improving its radiated noise level, the common method is to increase the thickness of the shell or increase the height, thickness or number of ribs. However, these measures are limited by the mold processing and injection molding process, so it is difficult to realize, and it will also lead to a significant increase in the weight of the air filter or resonator, and the c...
