【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、従来の方法のみではまだ充分とは言えず、特に排気ガスの浄化 不足にいたってはさまざまな問題を抱えている。 例えば、ディーゼル車の黒煙の排出は前記触媒コンバータを使用しても有効に 対応出来ないという問題がある。 高温の排気ガスは、地球の温暖化等の環境悪化を起こしてしまうという問題が ある。 前記排気ガスの再燃焼方式も構造が複雑でコストも高いという問題があって、 そのいくつかは社会問題にもなっている。 そのほか、触媒コンバータとマフラーは排気管上に別々に設置されるため、空 間専有率が高くスペース効率が悪いという問題もあった。 However, the conventional method alone is not sufficient, and there are various problems, especially when exhaust gas purification is insufficient. For example, there is a problem that the emission of black smoke from a diesel vehicle cannot be effectively dealt with even by using the catalytic converter. There is a problem that high temperature exhaust gas causes environmental deterioration such as global warming. The exhaust gas re-combustion method also has a problem that the structure is complicated and the cost is high, and some of them are social problems. In addition, since the catalytic converter and the muffler are installed separately on the exhaust pipe, there is a problem that the space occupation rate is high and the space efficiency is low.

【実施例】【Example】

以下、本考案の実施例を図面に基づいて詳しく説明する。 図1は本考案の実施例を示す断面図である。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of the present invention.

【0008】 本実施例の排気浄化マフラーは、排気管1の途中に膨張室を有する膨張型のマ フラーを基本形とし、ケーシング2と、エンジン側からの排気をマフラー内へ導 く吸入管3と、マフラーから外へ出す排出管4と、水を入れる注水口5と、水を 溜めるタンク部6と、水を出す排水口7と、を主要な構成としている。The exhaust purification muffler of the present embodiment is basically an expansion type muffler having an expansion chamber in the middle of the exhaust pipe 1, and has a casing 2 and an intake pipe 3 that guides exhaust gas from the engine side into the muffler. The main components are a discharge pipe 4 that goes out from the muffler, a water injection port 5 that puts water, a tank part 6 that stores water, and a drainage port 7 that puts out water.

【0009】 前記ケーシング2は、密閉された円筒状になっており、内部は、水溜めと膨張 室の役目をするタンク部6となっている。 前記吸入管3は、エンジンの排気管1に連通されケーシング2の上面からタン ク部6内に導入設置され下方向に伸び、タンク部6の下端近くでL字型に曲がっ ており、先端は常に水中に浸漬している。 また、この吸入管3はエンジン側への水の逆流を防ぐために立ち上がらせ、そ の途中に逆止弁3aを設け、また水中への排気抵抗を減少させるため先端に多数 の小孔3bを開設している。 前記排出管4は、ケーシング2の上端に吸入管3に対向し水が浸漬しない位置 に固設されており、吸入管3と同様にケーシング2の上面から立ち上げられ、タ ンク内の水が排気圧により直接外部に流出しない様にしてある。The casing 2 has a closed cylindrical shape, and the inside thereof is a tank portion 6 which functions as a water reservoir and an expansion chamber. The suction pipe 3 communicates with the exhaust pipe 1 of the engine and is installed from the upper surface of the casing 2 into the tank portion 6 and extends downward. The suction pipe 3 is bent in an L shape near the lower end of the tank portion 6 and has a tip end. Always submerged in water. In addition, this suction pipe 3 is raised to prevent backflow of water to the engine side, a check valve 3a is provided in the middle of the suction pipe 3, and a large number of small holes 3b are provided at the tip to reduce exhaust resistance to water. is doing. The discharge pipe 4 is fixed to the upper end of the casing 2 at a position facing the suction pipe 3 and not soaked with water. The discharge pipe 4 is raised from the upper surface of the casing 2 like the suction pipe 3 so that the water in the tank is removed. It is designed so that it does not directly flow to the outside due to exhaust pressure.

【0010】 前記注水口5は、ケーシング2の側面上端に近い所に注水を容易に行える注入 管5aが上向きに突設されており、その注入管5aの上端に開設され、通常は密 栓されている。 前記排水口7は、ケーシング2の底部に開設され、通常はドレーンボルト7a で密栓されており、水の交換時にドレーンボルト7aを外し排水させるしくみで ある。 前記ケーシング2の内周面には、車両の加減速等における水の流動を抑制する と共に、ケーシング2の剛性を確保するリブ8が付設されている。 尚、図示しないが、本実施例では、ケーシング2に水位センサー、温度センサ ー等を付けている。The water injection port 5 is provided with an injection pipe 5a protruding upward near the upper end of the side surface of the casing 2 so as to easily inject water, and the injection pipe 5a is opened at the upper end of the injection pipe 5a and is usually plugged. ing. The drainage port 7 is opened at the bottom of the casing 2 and is normally tightly plugged with a drain bolt 7a, which is a mechanism for removing the drain bolt 7a for draining water when exchanging water. The inner peripheral surface of the casing 2 is provided with ribs 8 that suppress the flow of water during acceleration and deceleration of the vehicle and ensure the rigidity of the casing 2. Although not shown, in this embodiment, the casing 2 is provided with a water level sensor, a temperature sensor and the like.

【0011】 本実施例の排気浄化マフラーでは、上記の構成になっており、使用される位置 は通常のマフラーと同じく排気管1の後端に設置する(図2参照)。エンジンか ら出たガスは、排気管に連通した吸入管3を通りマフラーへ導かれタンク部6の 水の中で放出される。このときの水の浄化力で排気ガス中の黒煙を吸着させ、同 時に消音とガスの温度低下が行われる。この後、浄化されたガスは圧力の低いタ ンク部6の上部へ向かい排気管4から外へ出ていく。また車両の加減速等による タンク内の水の流動や、熱による水蒸気も逆止弁3aによりエンジン側への流入 を防止出来るためエンジンへの負担はなく、水の補充や交換も容易である。また 浄化と消音を一つの装置で行えるため少ないスペースしかいらない。もしタンク 内の水が空になったとしても従来のマフラーと同じになっただけであり危険は生 じない。The exhaust gas purification muffler of the present embodiment has the above-mentioned configuration, and the position where it is used is installed at the rear end of the exhaust pipe 1 as in the case of a normal muffler (see FIG. 2). The gas emitted from the engine is guided to the muffler through the suction pipe 3 communicating with the exhaust pipe and is discharged into the water in the tank portion 6. Black water in the exhaust gas is adsorbed by the water purification power at this time, and at the same time, the noise is reduced and the gas temperature is lowered. After this, the purified gas goes to the upper part of the tank part 6 having a low pressure and goes out from the exhaust pipe 4. Further, since the check valve 3a can prevent the flow of water in the tank due to the acceleration and deceleration of the vehicle and the steam due to heat from flowing into the engine side, the engine is not burdened and the water can be easily replenished or replaced. In addition, there is only a small space because purification and noise reduction can be done with one device. Even if the water in the tank becomes empty, it will be the same as the conventional muffler and no danger will occur.

【0012】 以上、本考案の実施例について図面を用いて詳述したが、その具体的な構成は この実施例に限定されるものではなく、本考案の要旨を逸脱しない範囲における 変更があっても本考案に含まれる。The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are modifications within the scope of the present invention. Also included in the present invention.

【0013】 例えば、ケーシング2に冷却フィンを付けることも出来る。 また、ケーシング2内にカーボン除去フィルターを設け、水を循環して交換頻 度を減らすことも出来る。 また、通常のマフラーや触媒コンバータと併用しても良いし、触媒物質をタン ク内に設置しても良い。For example, the casing 2 may be provided with cooling fins. Further, a carbon removal filter may be provided in the casing 2 to circulate water to reduce the frequency of replacement. Further, it may be used together with an ordinary muffler or a catalytic converter, or the catalytic substance may be installed in a tank.

【考案の効果】[Effect of device]

以上、詳細に説明したように、本考案の排気浄化マフラーでは前記構成とした ため、マフラー内に浄化用の水を入れることが出来、本来のマフラーの役割であ る消音効果に加え、排気ガス中の黒煙やほこりを取り除く効果と、排気ガスの大 気への放出温度を下げる効果があり、大気の汚染を軽減させることが出来る。 また、十分な清浄力があるため触媒は不要となり、スペース効率が高くなる。 構造も簡単であり、どこでも手に入る水を使うことで、安価で容易に補充や交 換が実施できるため、常に清浄力の強い状態にしておくことが出来る。 以上の様な効果を得ることが出来る。 As described above in detail, since the exhaust purification muffler of the present invention has the above-described configuration, purification water can be put in the muffler, and in addition to the muffling effect which is the original function of the muffler, It has the effect of removing the black smoke and dust inside, and the effect of lowering the temperature at which exhaust gas is released to the atmosphere, which can reduce air pollution. In addition, since there is sufficient detergency, a catalyst is unnecessary and space efficiency is improved. It has a simple structure and can be easily replenished and replaced at low cost by using water that can be obtained anywhere, so it is possible to keep the cleaning power always strong. The above effects can be obtained.
