  2. 1. On Reduction of Nitrogen Oxides in Heavy-Duty Engines : with NOx Model Feedback, PPC and SNCR

    Author : Kenan Muric; Förbränningsmotorer; []
    Keywords : aftertreatment; emissions; Engine simulation; engine modeling; SNCR; PPC Engine;

    Abstract : European emission legislation has in recent years put a strict limit on NOx emissionsfrom heavy-duty truck engines. EGR and selective catalytic reduction are the two mostcommon technologies applied in a modern heavy-duty diesel engine to fulfill the legislation. READ MORE
