Abstract
【選択図】図1
Description
本実施形態1に係る触媒加熱装置を、図1を参照して説明する。この触媒加熱装置1は、自動車の排気通路5に設けられた浄化触媒6を加熱するものである。触媒加熱装置1は、排気通路5の浄化触媒6の上流下面に設けた上部を開放した水溜まり部2と、水溜り部2の上方に配備され、マイクロ波を放射することにより水溜り部2に貯蔵された水分を加熱して水蒸気を発生させるマイクロ波放射装置3(マイクロ波放射アンテナ30と、マイクロ波発振器31からなる)と、マイクロ波放射装置3を制御する制御装置4とを備える。制御装置4は、この自動車の始動時において、所定時間にわたりマイクロ波放射装置3からマイクロ波を放射させるように制御する。
実施形態1の変形例は、水溜まり部2に、電磁波吸収体を配設する。電磁波吸収体7としては、特に限定するものではないが、マイクロ波の照射によって短時間で高温に加熱されるものであればよく、例えば、炭素原子又は炭素を含む分子を主成分とするマイクロコイル、具体的にはカーボンマイクロコイルを用いることができる。そして、カーボンマイクロコイルは短時間で300℃まで昇温可能であるが、酸素のある雰囲気下では、600〜700℃程度で炭化する。そのため、800℃以上になることがある自動車の排気通路5に配設する本実施形態においては、カーボンマイクロコイルを薄い被覆層で覆うことが好ましい。また、カーボンマイクロコイルの他に活性炭を利用することもできる。
本実施形態2に係る触媒加熱装置を1、図3を参照して説明する。この触媒加熱装置1は、実施形態1と同様、自動車の排気通路5に設けられた浄化触媒6を加熱するものである。具体的には、排気通路5の浄化触媒6の上流側に液体を噴射する噴射装置と、この噴射装置と対面する箇所に配備され、電磁波を放射することにより噴射装置2Aから噴射される霧状の液体を加熱して水蒸気を発生させる電磁波放射装置3と、電磁波放射装置3を制御する制御装置4とを備え、制御装置4は、車の始動時において、所定時間にわたり電磁波放射装置3から電磁波を放射させるように電磁波放射装置3を制御するようにしている。
本実施形態3に係る触媒加熱装置1は、水の噴霧をプリンタインクジェットと同様に構成される噴射装置によって高速高圧ジェットで触媒6の端面に吹き付けるように構成する。このとき、噴射装置の噴射ノズル部分に電磁波吸収体を巻き付け、マイクロ波放射装置3からマイクロ波を放射して噴射ノズル部分を加熱し、圧縮して噴射することで200℃以上として触媒端面に吹き付ける。これによって触媒6の端面をより効果的に加熱・昇温することができる。また、マイクロ波放射装置3を設けることなく、噴射ノズル部分を他の方法、例えば電熱線等によって加熱することもできる。
