With the advent of increasingly stringent emissions regulations for both new and existing vehicles, there is a need to manage aftertreatment devices ever more carefully. We have extensive experience in the development of diesel aftertreatment control technology for both OEM and retrofit applications.
Our innovative technology has been developed using re-usable methodologies that enable us to quickly adapt and create solutions for ever more stringent regulations.
As an example we have developed an innovative solution to a problem of soot accumulation in diesel particulate filter (DPF). In automotive applications soot accumulates in the DPF until the high temperatures cause it to be burnt-off, however, it was found that the exhaust stream on commercial vehicles, such as city buses, may never be hot enough to regenerate the DPF.
The solution is to artificially boost the exhaust temperature periodically by combusting fuel dosed upstream of the Diesel Oxidation Catalyst (DOC), however, it is challenging to do this while safely keeping the DOC exit temperature steady at around 600° C.
