“…Hosseini et al [28] also support this idea by showing that the honeycomb design facilitates a significant increase in surface area for catalytic reactions, allowing for a more efficient oxidation process of CO emissions into CO2. On the other hand, research by Yang et al [29] presented relevant findings, indicating that proper inlet and outlet angle adjustments can improve combustion efficiency and reduce fuel consumption in vehicles. Similar research by Shah et al [30] revealed that increased backpressure due to overlapping can have a positive effect on more complete combustion.…”

Increased exhaust emissions from motor vehicles have become a major concern in efforts to reduce air pollution. One developed solution is the use of transition metallic catalytic converter (TMCC) technology in vehicle exhaust systems. This study aims to compare the fuel consumption efficiency of three types of exhaust systems, namely standard exhaust without a catalyst (STD WC), the standard exhaust with Original Equipment Manufacturer catalyst (STD OEM), and an exhaust system equipped with a Copper-Coated Chrome Metallic Catalytic Converter (TMCC CuCr). The data analysis method employed a quantitative approach by collecting fuel consumption data at each rpm and analyzing the mean and standard deviation. The research findings indicate that STD OEM has a lower average fuel consumption (0.80 liters per hour) and smaller standard deviation (0.06) compared to TMCC CuCr (0.83 liters per hour and 0.07). Although TMCC CuCr demonstrates good efficiency, STD OEM remains the best choice in terms of fuel efficiency. However, if the differences in fuel consumption and standard deviation are considered insignificant, TMCC CuCr could be a more economical alternative with its affordable price and greater material availability. Furthermore, its fuel consumption performance is not significantly different from that of STD OEM.

“…A dual-zone monolith consisting of a high-celldensity core and a low-cell-density outer annulus did not improve the performance of the CC in terms of the light-off [38]. However, Yang et al [40] proposed a new monolith structure with uniformly changing cell density and a new heater, which improved the flow field uniformity and NO conversion.…”

Despite the current boost in the use of electric vehicles to reduce the automotive sector’s footprint, combustion vehicles are and will be present in our cities in both the immediate and long term. In this sense, catalytic converters, which are exhaust gas post-treatment systems for vehicle emission control, are critical for complying with increasingly stringent environmental regulations. This work proposes a systematic review to identify the most relevant knowledge regarding the parameters (materials, geometries, and engine conditions), conditions (cold start, oxygen storage, and deactivation), and mathematical models to consider in the design of catalytic converters. The Scopus database contains 283 records related to this review’s objective. After applying the inclusion and exclusion criteria, 65 reports were retrieved for evaluation. A table was created to present the results and prepare this manuscript. The evaluation revealed that the following topics were active: the study of non-noble catalyst materials, as well as new substrate materials and geometries, for designing more compact and cost-effective catalytic converters; the development of strategies to improve conversion during cold starts; and the development of accurate and fast estimation models.
