METHOD TO DETERMINE THE QUANTITY OF METAL POWDERS ACCUMULATED IN A PARTICULATE FILTER FOR AN INTERNAL COMBUSTION ENGINE

A method to determine the actual quantity of metal powders or ashes trapped in a particulate filter (10), which involves determining an estimated value of the quantity of metal powders trapped in theparticulate filter (10) based on an estimation model (20, 21, 22, 23); determining a measured value o...

Beschreibung
Zusammenfassung:	A method to determine the actual quantity of metal powders or ashes trapped in a particulate filter (10), which involves determining an estimated value of the quantity of metal powders trapped in theparticulate filter (10) based on an estimation model (20, 21, 22, 23); determining a measured value of the quantity of metal powders trapped in the particulate filter (10); updating the estimated value of the quantity of metal powders trapped in the particulate filter (10) as a function of the measured value; and determining the actual quantity of metal powders or ashes trapped in a particulate filter (10) as a function of the update of the estimated value of the quantity of metal powders trapped in the particulate filter (10). 一种用于确定在微粒过滤器(10)中捕获的实际的金属粉末或灰量的方法，其包括：基于估算模型(20,21,22,23)确定在微粒过滤器(10)中捕获的金属粉末量的估算值；确定在微粒过滤器(10)中捕获的金属粉末量的测量值；根据测量值来更新在微粒过滤器(10)中捕获的金属粉末量的估算值；并且根据在微粒过滤器(10)中捕获的金属粉末量的估算值的更新来确定在微粒过滤器(10)中捕获的实际的金属粉末或灰量
