Inlet structure of novel air filter

Abstract

The invention belongs to the technical field of air purification of automobile engines and particularly relates to an inlet structure of a novel air filter. The inlet structure comprises an inlet part and a coarse filter which are arranged in the same shell. The inlet structure is characterized in that the inlet part comprises an air inlet, a round air inlet pipeline, an arc-shaped air inlet pipeline and an air inlet grid, wherein the air inlet grid is integrally connected with a shell of the coarse filter, and rib plates are arranged on the lower side; the coarse filter comprises an oil pool and a steel-wire filtering net; the upper end of an outlet of the coarse filter is connected with a fine filter. The inlet structure has the advantages that the structure is simple and the use is convenient; under the premise of guaranteeing the filtering efficiency, air inlet resistance can be effectively reduced, and more conformity to the flowing characteristic of fluid is achieved; the cost is low; the popularization and application are facilitated.

Description

(1) Technical field [0001] The invention relates to a novel air filter inlet structure, which belongs to the technical field of air purification of automobile engines. (2) Background technology [0002] As my country's emission standards enter the National IV stage, the quality of filter products also needs to be improved accordingly. In view of my country's current fuel quality and air quality, the performance improvement of filter products is crucial to the realization of emission standard upgrades. [0003] The air filter is an important part of the engine intake system. Its function is to provide clean and dry air to the engine, reduce the wear of cylinders, pistons and piston rings, and promote combustion. It has a direct impact on engine power and economy. At present, most heavy-duty vehicles driving in areas with harsh environments and poor maintenance conditions will choose oil bath / dry combined air filters. [0004] The main performance of the air filter is filtrat...

Problems solved by technology

[0006] In addition, in order to achieve high power output for heavy-duty trucks, the intake air volume must be increased. Therefore, the volume of air filters used in many heavy-duty trucks is generally large. Through analysis, it is found that the design of the filter product structure has not fully considered The fluid flow characteristics are only designed to achieve a certain function without being designed and developed from the overall height, resulting in unreasonable design of many internal structures of the product, resulting in large air intake resistance, resulting in a large energy loss, and the overall performance of the engine. to effectively improve, and even affect its service life in severe cases
