Composite cylinder cap with air filter

Abstract

A compound cylinder head cover with an integrated air filter comprises a cylinder head base, cylinder head cover, clip, oil filter plate, filter bracket, filter paper, filter ring, seal ring, screw, gasket and metal lining for the screw. The cylinder head base with the filter bracket, filter ring and filter paper and the cylinder head cover occupy enough hexahedron space in the front of mobile engine chamber. The filter bracket is located in diagonal in the hexahedron space. By using engineering plastics to substitute aluminium alloy for the compound cylinder head cover can integrate functions, save the front space of the engine chamber and maximum the filter area.

Description

(1) Technical field: [0001] The invention relates to a plastic cylinder head cover for automobiles, in particular to a composite cylinder head cover with an air filter. (two) background technology: [0002] With the development of modern automobiles, customers have higher and higher requirements for reducing the noise of automobiles. In 2005, my country also listed the noise limit standard as a mandatory standard. Generally speaking, the plastic cylinder head cover reduces the noise by about 3dB compared with the cast aluminum cover. Many large companies in the world are studying this form. The original cast aluminum cylinder head cover has the following disadvantages: heavy weight; it takes up a lot of space to be arranged in the car together with the independent air filter; the level of noise isolation is poor; the integration function of accessories is poor; Some manufacturers, in order to save space, better block noise and prevent radiation, have adopted composite cyli...

AI Technical Summary

Problems solved by technology

The original cast aluminum cylinder head cover has the following disadvantages: heavy weight; it takes up a lot of space to be arranged in the car together with the independent air filter; the level of noise isolation is poor; the integration function of accessories is poor;

Some manufacturers, in order to save space, better block noise and prevent radiation, have adopted composite cylinder head covers with air filters. However, the effective ventilation area and effective filter area of ​​the existing composite cylinder head covers Can not be large enough, affecting the ventilation, filtering effect and dust removal ability
