When it comes to reducing the nitrogen oxide (NOx) emissions of diesel-burning commercial vehicles, selective catalytic reduction (SCR) is firmly in place as today’s technology. And these systems are ...
This study focuses on optimizing the selective catalytic reduction (SCR) system to reduce urea deposits and enhance overall system performance. Both computational fluid dynamics (CFD) simulations and ...
Beyond liquid urea injection, dosing and control solutions, Tenneco’s full suite of technologies for aftertreatment includes custom-engineered SCR catalysts and substrates. Along with joint ...
GREENSBORO, N.C. — During a recent visit to Volvo Group’s North American headquarters, a group of trade press journalists was challenged to identify which of two seemingly identical trucks was ...
Modern medium- and heavy-duty trucks have sophisticated exhaust aftertreatment systems that can include a diesel oxidation catalyst (DOC), diesel particulate filter (DPF) and selective catalytic ...
An off-road machine’s selective catalytic reduction (SCR) system converts toxic nitrogen oxides in a diesel’s exhaust—nitrogen monoxide (NO) and nitrogen dioxide (NO2)—into harmless nitrogen, water, ...
