Method for controlling exhaust gas aftertreatment system for exhaust system of internal combustion engine

A method of controlling an exhaust gas aftertreatment system (14) having at least one catalytic converter (15, 17) arranged along an exhaust gas conduit (10) and a combustor (21) adapted to introduce exhaust gas into the exhaust gas conduit (10) wherein a combustion chamber (22) is defined within the combustor (21), the combustion chamber (22) receives fresh air and fuel from an injector (27) through an air supply circuit (23); the method comprises receiving a temperature and pressure sensor (33, 34) between the pumping device (24) and the combustor (21) or away from the combustor (21); acquiring a pressure signal (P33) generated by combustion in the combustion chamber (22) and detected by said temperature and pressure sensors (33, 34); and controlling combustion in the combustion chamber (22) as a function of the pressure signal (P33). 公开了一种控制废气后处理系统(14)的方法，所述系统具有沿排气导管(10)布置的至少一个催化转化器(15、17)和燃烧器(21)，所述燃烧器(21)适于将废气引入排气导管(10)，其中在燃烧器(21)内限定有燃烧室(22)，所述燃烧室(22)通过空气供给回路(23)接收新鲜空气和来自喷射器(27)的燃料；所述方法包括介于泵送设备(24)和燃烧器(2
