The aftertreatment system is a network of components designed to work in concert to reduce greenhouse gases, but if even one of those pieces is out of tune the efficiency of the entire system is dragged down. 

However, some of this is unavoidable. The plugging of the DPF, for example, is a byproduct of it doing its job – catching particulate matter and anything else that finds its way downstream, like engine oil that’s blown-by the rings.

In this week's 10-44, Jason and Matt visit again with Shawn Whitacre, senior staff engineer with Chevron Lubricants, to discuss the ins and outs of aftertreatment and soot.
