摘要

Cylinder deactivation for medium and heavy-duty diesel engines is of interest because it allows: Thermal management of the aftertreatment to keep the SCR system operating at high NO_x conversion rates, while also; Reducing fuel consumption during light load operation; Normally, thermal management means using fuel in some form to make heat, so making heat while using less fuel is a huge advantage; However, CDA also changes the vibration signature of an engine, and that is our topic today; All data was taken in a test cell on a 15-liter HD diesel engine.
