Method for the post-treatment of exhaust gases by subsequent injection of fuel in a diesel-type internal combustion engine provided with a pre-catalyst and a particulate filter |
摘要 |
A process is proposed for exhaust gas aftertreatment by afterinjection of fuel in a diesel internal combustion engine with a precatalyst and a particulate filter, in which process the afterinjection NE is performed as a function of the temperature in the area of the precatalyst T<SUB>cat </SUB>and of the state of charging of the particulate filter. Since this process operates with especially high efficiency in heretofore critical short-distance operation of diesel internal combustion engines, the strict requirements of future legislation relating to exhaust gas emissions can immediately be met. |
