【考案の詳細な説明】 （産業上の利用分野） この考案は内燃機関などに装着されるエアクリーナに関

ト全断面を均等に行きわたるようになる。(Prior Art) Conventionally, it is known that a cylindrical honeycomb element is housed in a cylindrical casing, and an inlet pipe and an outlet pipe are provided on the central axis so as to face the center of the end face of the element (for example, actual (Kaisho 62-114614). However, this is difficult to diffuse and flow air from the base end of the inlet pipe toward the honeycomb element and the outer periphery, and the peripheral portion of the element is not used as an effective filtration area. The honeycomb element 22 is tilted so that it is almost parallelogram when viewed from the side.
I proposed an air cleaner 20 that accommodates the
No. (Actual Kaihei 1-132218 bulletin)). This is the inlet pipe
The air flow between the 23 and the outlet pipe 24 is distributed evenly over the entire cross section of the honeycomb element.
このエアクリーナは自動車のエンジンルームのスペース
の制約などがあるため断面が長円形にしてある。This air cleaner has an oval cross section due to the space limitations of the engine room of the automobile.

を設けたものがある。A muffler is attached to the air cleaner to prevent emission of engine noise, but there is a muffler provided with a muffler along the casing as disclosed in Japanese Utility Model Laid-Open No. 58-40556.

たりする。(Problems to be Solved by the Invention) In the air cleaner as shown in FIG. 3, the inclination angle θ should not be large in terms of ventilation resistance. In addition, if a silencer is added to the casing, since a considerable volume is required, the portion shown in FIG. 3A is added, and the total length l 1 of the air cleaner becomes large. This causes trouble when the air cleaner with the resonator attached is arranged in a space as small as possible, and sometimes the silencer is not provided.

を併設したものである。(Means for Solving the Problems) An air cleaner according to the present invention is configured such that the end faces of the honeycomb element and the end wall of the casing are inclined so as to be parallel to the end wall so that the shapes of the honeycomb element and the casing are parallelograms when viewed from the side. The outer wall is provided to form a vacant chamber, and the resonator is installed without extending the entire length of the air cleaner.

Although the conventional air cleaner has a small triangular space as shown in FIG. 3B, the effective passage cross-sectional area is not reduced and the ventilation resistance is not increased.

When viewed from the side as shown in FIG. 1, both the casing 2 and the honeycomb element 3 form a parallelogram with an inclination angle θ, and the cross section is oval as shown in FIG. An inlet pipe 4 and an outlet pipe 5 are attached to the casing 2 so as to be offset to the corners on the acute side of the parallelogram, and the end walls 6 and 7 are parallel to the end faces 14 and 15 of the honeycomb element 3. An outer wall 9 parallel to the end wall 7 is provided outside the end wall 7 to define an empty space 10 therebetween, and the empty space 10 communicates with the outlet pipe 5 through a through hole 11 formed in the pipe wall of the outlet pipe 5. To form a resonator.

The body 12 of the casing 2 is divided into two parts across the casing 2, the cross sections thereof are combined, and a clip 13 for locking the same is provided. The total length l 2 of the air cleaner in FIG. 1 is the same as the total length l 2 in the case where the resonator is not provided in FIG.

The outlet pipe 5 is provided with a resonator having the empty chamber 10 as a resonance chamber to prevent emission of engine noise.
