The Volvo EMS engine management system, which offers completely electronic function control, is installed in the D13A440. The system offers more precise diagnostics and troubleshooting, as well as effective engine management. The dashboard’s display presents the data in an easy-to-understand way.
Selective Catalytic Reduction (SCR) technology is used to treat the exhaust gases in addition to optimizing the combustion process. This procedure results from the injection of AdBlue reagent into the exhaust gases prior to their transfer to the system’s catalytic converter. Emissions are decreased by this reagent’s reaction with nitrogen oxides. The engine is approved in compliance with the Euro 4 emission standards because of this system.
