Real Driving Emission Efficiency Potential of SDPF Systems without an Ammonia Slip Catalyst

Optimization of the Urea Injection Angle and Direction: Maximizing the Uniformity Index of a Selective Catalytic Reduction System

“…Recently, with increasing attention toward the environmental pollution of automobiles, strengthened emissions regulations were adopted, making the installation of additional aftertreatment equipment inevitable [2,3]. For diesel engines, three-way catalyst devices cannot be installed due to the low exhaust gas temperature and operating air-fuel ratio; numerous aftertreatment equipment installations are necessary [4,5].…”

Development of a 2D SCR Catalyst on a Diesel Particulate Filter Model for Design and Control Applications to a Ultra Low NOx Aftertreatment System

“…Georgiadis et al [48] designed a system that can significantly reduce the nonuniformity of the NH 3 coverage fraction in the SCR-F leading to lower NH 3 slip.…”

Simulation Study on Effect of Gas Charging and Egr in a Dual-Fuel Engine

“…[7] In the after-treatment, novel technologies like combination of after-treatment modules such as SCRF (Combination of SCR and DPF) are being tested. Some of the present challenges for the after-treatment technologies include cost reduction, cold phase emission reduction and optimization of control strategy for Urea-SCR technology [7][8][9]. In-cylinder combustion strategies provide the opportunity to improve thermal efficiencies along with reducing emissions.…”
