この考案は、内燃機関用エアクリーナの騒音低減装置に
関する。[Detailed Description of the Invention] This invention relates to a noise reduction device for an air cleaner for an internal combustion engine.
内燃機関の吸気は、間歇的に急激に行われるので、吸入
の都度騒音が発生する。Intake in an internal combustion engine occurs rapidly and intermittently, so noise is generated each time the engine takes in air.
特に気化器では、吸気量をスロットルバルブで絞ったり
するので、騒音の発生が太きい。In particular, carburetors generate a lot of noise because the amount of intake air is restricted by a throttle valve.
又、エンジン内部の燃焼音やバルブ音等が、吸入孔を伝
播して気化器に伝わってくるので、気化器の入口付近で
、大きい騒音が発生する。Further, combustion noise, valve noise, etc. inside the engine propagate through the suction hole and reach the carburetor, which generates a large amount of noise near the inlet of the carburetor.
従来エアクリーナのボリュームを大きくしたり、エアク
リーナの入口管を細く長くしたりして、吸気騒音を少く
しているが、エンジン出力との関係があって限度がある
。Conventionally, intake noise has been reduced by increasing the volume of the air cleaner or making the air cleaner inlet pipe thinner and longer, but there is a limit due to the relationship with engine output.
この考案は、かかる点に鑑み改善したもので、以下図面
に示す本考案の実施例について説明する。This invention has been improved in view of these points, and an embodiment of the invention shown in the drawings will be described below.
エアクリーナ１は、箱体２に入口孔３と出口孔４が設け
てあって出口孔４の内側に、円筒状の空気を濾過するク
リーナエレメント５が設けである。The air cleaner 1 has an inlet hole 3 and an outlet hole 4 provided in a box body 2, and a cylindrical cleaner element 5 for filtering air is provided inside the outlet hole 4.
尚、クリーナエレメント５は、−側を箱体２に密着させ
、他側は覆板６によって塞いである。The negative side of the cleaner element 5 is brought into close contact with the box body 2, and the other side is closed by a cover plate 6.
エアクリーナ１は、出口孔４を吸気管Ｉで気化器８に連
結するもので、気化器８は、エンジンの吸気孔に連結す
る。The air cleaner 1 has an outlet hole 4 connected to a carburetor 8 through an intake pipe I, and the carburetor 8 is connected to an intake hole of an engine.
而して本考案は、パンチングプレートや金網等の多孔板
９でグラスウール等の防音材１０を包んだ砲弾状のスプ
リッタ１１を設け、該スプリッタ１１を先端が出口孔４
に臨むようにして覆板６に取着する。Therefore, the present invention provides a bullet-shaped splitter 11 in which a soundproof material 10 such as glass wool is wrapped with a perforated plate 9 such as a punching plate or a wire mesh, and the splitter 11 is connected to the exit hole 4 at the tip.
Attach it to the cover plate 6 so as to face it.
尚、スプリッタ１１は、第２図に示すように、防音材１
０の内外を多孔板９テ覆った中空状のものにしてもよい
。Incidentally, the splitter 11 has a soundproofing material 1 as shown in FIG.
It is also possible to use a hollow structure in which the inside and outside of the hole are covered with a perforated plate 9.
作用について説明する。The effect will be explained.
吸入空気は、入口孔３から箱体２内に入り、クリーナエ
レメント５で濾過さｈτクリーナエレメント５の内側に
流れ、出口孔４から吸気管Ｔを通って、気化器８に流れ
る。Intake air enters the box body 2 from the inlet hole 3, is filtered by the cleaner element 5, flows inside the cleaner element 5, and flows from the outlet hole 4 through the intake pipe T to the carburetor 8.
そして、吸入空気は、適宜スプリッタ１１内を通り抜け
ることができ、吸気音の消音ができる。The intake air can pass through the splitter 11 as appropriate, and intake noise can be muffled.
気化器８側から反射してくる吸気騒音や、パルプ音等の
エンジン騒音は、出口孔４を通ってスプリッタ１１に当
り、該スプリッタ１１の防音材１０に吸収されて騒音の
低減ができる。Engine noise such as intake noise and pulp noise reflected from the carburetor 8 side passes through the outlet hole 4 and hits the splitter 11, where it is absorbed by the soundproofing material 10 of the splitter 11, thereby reducing the noise.
こうして、気化器８に近い発生源に近い個所で騒音を低
減できる。In this way, noise can be reduced at a location near the source near the carburetor 8.
又、スプリッタ１１はクリーナエレメント５の内側で、
吸気抵抗になることもないので、エンジン出力に影響を
及ぼさない。Moreover, the splitter 11 is inside the cleaner element 5,
Since it does not create intake resistance, it does not affect engine output.
以上説明したように、この考案は、エアクリーナの箱体

宜吸気が通ることができて吸気音の低減が計れ、気化器
側から伝播シてくる吸気騒音やエンジンのメカニカル騒
音等もスプリッタに当って、吸音することができ、全体
として、吸気の騒音を低減できて静かになる。As explained above, this invention is a cylindrical cleaner element that is installed inside the box of the air cleaner, the negative side of which is in close contact around the outlet hole of the box, and the other side of which is covered with a cover plate. The splitter wrapped in a perforated plate was installed with the tip facing the outlet hole, allowing intake air to pass through the splitter appropriately, reducing intake noise, and reducing intake noise transmitted from the carburetor side and the engine. Mechanical noise can also be absorbed by the splitter, reducing intake noise and making it quieter overall.
又、スプリッタは、吸気抵抗になるようなことがなく、
エンジン出力等に影響ない。In addition, the splitter does not cause intake resistance,
No effect on engine output etc.
こうして、発生源に近い個所で騒音を低減できる。In this way, noise can be reduced at locations close to the source.
