“…Against this background, internal and external thermal management measures must be applied, such as intake and exhaust throttling, delayed and post-injection strategies for late combustion phasing, cylinder deactivation, high exhaust gas recirculation (EGR) rates, variable valve control/internal EGR, HC dosers, electric exhaust gas heaters, and various non-catalytic or catalytic burner systems, cf. [10][11][12][13][14][15].…”

This study investigates geometric parameters of commercially available or recently published models of catalyst substrates for passenger vehicles and provides a numerical evaluation of their influence on heat-up behavior. Parameters considered to have a significant impact on the thermal economy of a monolith are: internal surface area, heat transfer coefficient, and mass of the converter, as well as its heat capacity. During simulation experiments, it could be determined that the primary role is played by the mass of the monolith and its internal surface area, while the heat transfer coefficient only has a secondary role. Furthermore, an optimization loop was implemented, whereby the internal surface area of a commonly used substrate was chosen as a reference. The lengths of the thin wall and high cell density monoliths investigated were adapted consecutively to obtain the reference internal surface area. The results obtained by this optimization process contribute to improving the heat-up performance while simultaneously reducing the valuable installation space required.

<div class="section abstract"><div class="htmlview paragraph">In the Journey towards Zero Emission and decarbonization, with emerging advancement in technology form current BS6 to near future EURO7 standards of emission, these emission norms are achievable when we amalgamate with an assistive technology of <b>Electrically Heated System for thermal management in Diesel emission control i.e., called CatVap®.</b> With the increasingly stringent limits on vehicle pollutants- including NOx emission levels are fulfilled with <b>Twin Urea Dosing mechanism.</b> These comprehensive lists of advanced technology to converge lowest NOx emissions without increasing CO2 emissions. The Major effort in the existing structure is to accelerate the SCR temperature and enhance the conversion efficiency of NOx in Real Drive Emission during cold start and low load duty cycle. <b>CatVap®system</b> provides sufficient thermal energy to facilitate rapid heating in the course of low load cycles and cold city rides for efficient gas conversion. As they are used to accelerate the light-off temperature for Diesel Oxidation Catalyst (DOC) and Selective Catalytic Reduction (SCR), this system is also highly adaptable for effective regeneration in Diesel Particulate Filter (DPF) and overall, it is an important promoter to accomplish Zero emission Internal Combustion Engines. Albonair is targeting towards optimization of well adapted and cost-effective <b>CatVap</b> technology and dual dosing system to improve BS6 emission standards and to meet BS7/Euro7 regulations. The Development cost and the estimated timeline to encounter BS7 System would not be much challengeable when compared to the implementation of BS6 system.</div></div>
