Exhaust gas aftertreatment from MAN Engines

To comply with the most important global emission guidelines, MAN Engines offers its customers numerous and flexible solutions for emission reduction. Together with its partners, MAN Engines can provide a wide range of variants for exhaust gas aftertreatment, from exhaust gas recirculation to diesel particulate filters and even SCR systems. As a result, we can provide you with solutions which are tailored to your specific requirements. Our engines thus satisfy the most modern emissions requirements, such as EU Stage V or US Tier 4, while also allowing for emissions downgrades in countries with less strict emission requirements. As customers you also benefit from the high quality of the components used, which have been proven not just in engines from MAN Engines, but also hundreds of thousands of times in the large-scale production of MAN commercial vehicles.

Exhaust gas aftertreatment (EAT) with SCR

Modular exhaust gas aftertreatment (EAT) from MAN Engines excels due to its compact design and high flexibility in restricted installation spaces. It allows for a wide range of installation possibilities and system integration tailored to specific customer needs, as the individual components can be positioned differently. Modular EAT is available over all segments and for many different applications. The centrepiece of the EAT is an SCR catalytic converter (selective catalytic reduction), which helps to reduce the nitrogen oxides (NO_x) in the emissions in a targeted manner. To do this, a 32.5 percent AdBlue^© fluid solution is metered in an SCR mixer and then injected continuously and directly into the exhaust tract. There, the solution reacts with the nitrogen oxides and converts them into water (H₂O) and harmless nitrogen (N₂). The system can either be used by itself, as SCR-only, or combined with other components such as a DOC/DPF (diesel oxidising catalytic converter/diesel particulate filter), to cover many different emission guidelines.
