Claims (4)
- エンジン排気系の選択還元型NOx触媒上流に尿素水溶液と圧縮空気との混合気を噴射する噴霧器と、触媒付近に配置される温度センサの情報などに応じて噴霧器への尿素水溶液と圧縮空気との混合気の供給量を制御する尿素噴射装置とを備える除雪トラックの選択還元型NOx触媒システムにおいて、グレーダの前側にエンジン排気系をレイアウトするべく、マフラをグレーダの前側に配置すると共にマフラの上方でグレーダブラケットとの干渉を避けられる位置に尿素噴射装置を支持する一方、前記触媒をマフラに収装すると共に前記噴霧器や前記温度センサがマフラに取り付けてあり、マフラと尿素噴射装置との間に介在する配管や配線を雪などの付着および堆積から保護するためのカバーを設けたことを特徴とする除雪トラックの選択還元型NOx触媒システム。
- カバーは、マフラ側を自由端として基端が尿素噴射装置のケーシングに取り付けられ、マフラ側の自由端部を基端側と取り外し可能に構成したことを特徴とする請求項1に記載の選択還元型NOx触媒システム。
- カバーは、断面略コ字形に形成したことを特徴とする請求項1に記載の選択還元型NOx触媒システム。
- カバーは、その内側に配管や配線を保持するクランプを備えたことを特徴とする請求項1に記載の選択還元型NOx触媒システム。
