Abstract
【解決手段】アウタシェル1により覆われ、内燃機関から排出される排気が導入されるインレットパイプ16と、排気を排出するアウトレットパイプ22とを備え、少なくともインレットパイプ16またはアウトレットパイプ22の一方あるいは両方でアウタシェル1内への開口側に、インレットパイプ16またはアウトレットパイプ22の断面積よりも狭めた狭窄部24を形成した。狭窄部24を設けたインレットパイプ16またはアウトレットパイプ22は、狭窄部24に向かって縮径するテーパ部26を有し、また、狭窄部24からアウタシェル1内に向かって拡径したフレア部28を設けてもよい。狭窄部24を設けたインレットパイプ16またはアウトレットパイプ22に、アウタシェル1内に開口する小孔30を設けた。
【選択図】図1
Description
アウタシェルにより覆われ、内燃機関から排出される排気が導入されるインレットパイプと、前記排気を排出するアウトレットパイプとを備えた内燃機関用マフラにおいて、
少なくとも前記インレットパイプまたは前記アウトレットパイプの一方で前記アウタシェル内への開口側に、前記インレットパイプまたは前記アウトレットパイプの断面積よりも狭めた狭窄部を形成したことを特徴とする内燃機関用マフラがそれである。
図1に示すように、1はアウタシェルで、アウタシェル1は円筒状の筒部2と、筒部2の両端を塞ぐ側壁部4,6とを備え、内部が中空に形成されている。中空内部は隔壁8,10により複数の第1〜第3拡張室12〜14に仕切られている。
内燃機関からの排気がインレットパイプ16に導入されると、インレットパイプ16内を流れる排気の一部が、貫通孔18から第2拡張室13に流入する。また、排気の一部が貫通孔20から第1拡張室12に流入し、更に、インレットパイプ16の一端の開口から第1拡張室12に流入する。第1拡張室12に流入した排気は隔壁10の図示しない孔を通って第2拡張室13に流入する。
