INSERTION TYPE EXPANSION PIPE-INTEGRATED AIR CLEANER AND ENGINE INTAKE SYSTEM WITH THEE AIR CLEANER APPLIED THERETO

摘要

PROBLEM TO BE SOLVED: To provide an insertion type expansion pipe-integrated air cleaner and an engine intake system with the air cleaner applied thereto in which an improvement in pressure absorption performance, a reduction in ventilation resistance, reductions in the number of components and fastening processes, an improvement in high-frequency noise, an improvement in pressure absorption of the intake system, and an improvement in Noise, Vibration, and Harshness (NVH) can be achieved.SOLUTION: The insertion type expansion pipe-integrated air cleaner includes an air cleaner body comprised of: a filter chamber 10A in which air is introduced from an outside, the filter chamber 10A having a chamber space provided with a filter, the chamber space being covered by an air cleaner cover 30; an expansion pipe chamber 10B extending to the filter chamber such that the introduced air is discharged from the expansion pipe chamber to the outside; and a female passage boss 11 through which the introduced air passes from the filter chamber to the expansion pipe chamber having a cross-sectional area smaller than a cross-sectional area of the expansion pipe chamber while the female passage boss divides the filter chamber and the expansion pipe chamber.SELECTED DRAWING: Figure 1
