Description
‐熱的エージング
この場合、触媒コンバータの熱負荷は、寿命にわたり、触媒活性のある表面の縮小を、特に、焼結により、溶融および/または800℃を上回る温度で、引き起こす。
‐化学的汚染
異物(燃料、オイル添加剤など)に対する化学反応は、触媒活性のあるコーティングを同様に破壊し得る。
‐機械的汚染
触媒コンバータの寿命中に、触媒活性のあるコーティングに、例えば、鉛、硫黄、燐、マンガン等により、または燃料および/またはオイルにより、増大する覆いが当てられ得る。
‐触媒コンバータの変換温度を決定するステップ、
‐変換温度を所定の閾値温度と比較するステップ、
‐変換温度が所定の閾値温度を下回った場合に、加熱装置を作動させるステップ。
‐自動車の走行キロ数、特に20,000キロメートル、
‐自動車の走行時間、特に100時間。
