Description
(i)一酸化炭素から二酸化炭素への酸化、(ii)未焼炭化水素から二酸化炭素および水への酸化、ならびに(iii)窒素酸化物から窒素および酸素への還元という3つの併発反応を触媒することを意図する。これら3つの反応は、TWCが、化学量論点またはその付近で稼働しているエンジンからの排気ガスを受け取ったときに、最も効率的に生じる。当該分野において周知であるように、ガソリン燃料を火花点火式(例えば、スパーク点火式)内燃機関で燃焼させたときに排出される一酸化炭素(CO)、未焼炭化水素(HC)、および窒素酸化物(NOx)の量は、主として燃焼シリンダ内の空燃比によって影響を受ける。化学量論的に均衡がとれた組成を有する排気ガスは、酸化ガス(NOxおよびO2)と還元ガス(HCおよびCO)の濃度が実質的に一致したものである。この化学量論的に均衡がとれた排気ガス組成を生成する空燃比は、一般的に14.7:1として与えられる。
実際のエンジンの空燃比/化学量論的なエンジンの空燃比 (1)
式中、1のラムダ値は化学量論的に均衡がとれた(または化学量論的)排気ガス組成を表し、1超過のラムダ値はO2およびNOxが過剰であることを表し、組成は「希薄」として説明され、1未満のラムダ値はHCおよびCOが過剰であることを表し、組成は「濃厚」として説明される。また、当該分野では一般に、空燃比が発生させる排気ガス組成に応じて、エンジンが作動する空燃比を「化学量論的」、「希薄」、または「濃厚」と呼び、したがって、化学量論的に運転されるガソリンエンジンまたは希薄燃焼ガソリンエンジンである。
(i)空気動力学的直径が10μm未満のPM10粒子、
(ii)直径2.5μm未満の微細粒子(PM2.5)、
(iii)直径0.1μm(100nm)未満の超微粒子、および、
(iv)50nm未満の直径によって特徴付けられるナノ粒子。
(i)ウォッシュコート充填が第1の区域>第2の区域であるか、あるいは、
(ii)ウォッシュコート組成物がNOx吸収剤触媒ウォッシュコート組成物であり、ウォッシュコート充填および合計貴金属充填の両方が第1の区域>第2の区域であり、
第1の区域は第2の区域の上流側に配設される。
NO+ 1/2 O2→NO2 (2)、および
BaO+NO2+ 1/2 O2→Ba(NO3)2 (3)
式中、反応(2)で、酸化窒素は白金の活性酸化部位で酸素と反応して、NO2を形成する。反応(3)は、無機硝酸の形態の貯蔵材料によるNO2の吸着を伴う。
Ba(NO3)2 → BaO + 2NO + 3/2O2 or Ba(NO3)2→ BaO + 2NO2 + 1/2 O2 (4)、および
NO + CO → 1/2N2 + CO2 (5)
(他の反応は、Ba(NO3)2+8H2→BaO+2HN3+5H2O、それに続くNH3+NOx→N2+yH2O、または2NH3+2O2+CO→N2+3H2O+CO2などを含む)。
(i)ウォッシュコート充填が第1の区域>第2の区域であるか、あるいは、
(ii)ウォッシュコート組成物がNOx吸収剤触媒ウォッシュコート組成物であり、ウォッシュコート充填および合計貴金属充填の両方が第1の区域>第2の区域であり、
ガスは第2の区域に接触するよりも先に第1の区域に接触する。
