Problems solved by technology

[0007] However, the suction channel 4 with technique ② 1 The size of the air filter with the resonator 103 should be increased. For example, when the above-mentioned air filter is installed on a two-wheeled vehicle with a small part installation space, the resonator 103 must have a specified volume and shape for noise reduction. , filter housing 1 1 The shape of the part is limited, so it cannot exert sufficient cleaning power
[0008] In addition, since it is in the suction channel 4 1 A resonator is added separately, so the number of parts and assembly man-hours increase, leading to an increase in cost

Abstract

To reduce a size of an air cleaner case, reduce manufacturing cost by forming the case readily, reducing intake noises, and furthermore reduce a size of an air cleaning device as compared with a device including a reserve tank and an air chamber separately provided from a sub chamber 48. This air cleaning device 25 for an engine includes an air cleaner case 42 divided into the dirty side and the clean side by a filter element 43. A sub chamber 48 is formed by partially partitioning a space of the clean side of the air cleaner case 42, and an outlet 55 of a blowby hose 34 for circulating blowby gas from a crank case 35 of an engine 16 and an inlet 54 of a secondary air supplying pipe 32 for supplying secondary air to an exhaust system of the engine 16 are connected to the sub chamber 48.

Description

technical field [0001] The present invention relates to an air cleaner device for a two-wheeled motor vehicle, and more particularly to an improvement in miniaturization of an air cleaner for a two-wheeled motor vehicle. Background technique [0002] As an air filter device for an engine, for example, ① an air filter device capable of reducing intake noise, and ② Japanese Patent Publication No. 60-32373 "Air Filter for Internal Combustion Engines" are known. [0003] Below by accompanying drawing 7 the technology of above-mentioned 1. is described. [0004] 7 is a side view of a conventional air cleaner device. The air cleaner device 100 is composed of an air cleaner case 101 , a connecting pipe 102 , and a resonator 103 . Wherein, the connecting pipe 102 is connected to the carburetor from the air filter housing 101 without illustration; Mounted on the outer peripheral surface of the connecting pipe 102 . The resonator 103 achieves a sound-absorbing effect by resonating ...
