Title:
内燃エンジンの排ガスを後処理する方法及び内燃エンジン
Document Type and Number:
Japanese Patent JP7450369
Kind Code:
B2
Abstract:
A method for the aftertreatment of the exhaust gas of an internal combustion engine combusting gaseous fuel. The exhaust gas is conducted via a CH4-oxidation catalytic converter, which for the CH4-oxidation and accordingly as catalytically active compound includes a pyrochlore and/or a beta polymorphous A-type (BEA) zeolite and/or a cobalt-nickel oxide. The exhaust gas to be conducted via the CH4-oxidation catalytic converter has an NO2 proportion, based on a total proportion of nitrogen oxides, of at least 15%.
