“…Hence, the challenge of improving this trade-off relationship exists with standard porosity (porosity of approximately 35%) substrates. However, with an advanced high porosity (approximately 48-50% after catalyst coating) cordierite substrate selection, the abovementioned trade-off can be enhanced [3,4]. The porosity configuration for cordierite substrate is shown in Figure 1.…”

“…Even though the efficiency of these engines is currently at a high level, there are still possibilities for further improvements both in performance and emissions, specifically for cost-competitive applications like generators (GenSets) and tractors. Typically, the associated concerns from the engine are higher particulate and NOx emissions, which cause environmental problems [3,4]. In light of the foregoing, the Indian government regularly updates the exhaust emission level regulations for engines.…”

The use of diesel engines for the transportation sector is ubiquitous and covers a broad continuum, like buses, trucks, agriculture, construction equipment, generators, and industrial applications. However, because of their increased use of off-road engines, they contribute more emissions in various sectors than on-road. As a result, worldwide, regardless of ongoing emission control efforts, these off-road, stationary engines also continue to be a substantial source of air pollutant emissions in the United States, European Union and Asian markets. Accordingly, while improving emissions performance, the selection of after-treatment system materials and the use of compatible after-treatment specification selections are also critical. This is only possible by effectively combining clean diesel technologies such as Fuel Injection Equipment (FIE), Turbocharger with Intercooler (TCIC), Cooled Exhaust Gas Recirculation (C-EGR), and after-treatment systems like Diesel Oxidation Catalyst (DOC), Selective Catalytic Reduction (SCR), and Diesel Particulate Filter (DPF). Overall, in this study, the influence of after-treatment system configurations and their effect on emission reduction performance are studied for three different DOC specifications based on emission testing for catalyst and size optimization. With the selected DOC catalyst specification, suitable combinations of DPF and SCR specifications are optimized further using GT-SUIT software simulation. This study was carried out during the conversion of a 15 kW NA engine to a 27 kW TCIC engine to meet diesel engine emission norms.

“…Additionally, this monitoring contributes to the decomposition of NO x , enhancing overall catalytic efficiency [27]. Since catalytic converters began to be used, the reduction of gases emitted by vehicles has been noted, and with recent advances in their durability and efficiency, they are relied upon to reduce pollution [28]. The working temperature of the catalytic converter is critical because when it is suitable, its work is more efficient.…”

This study focuses on the detailed analysis of exhaust emissions from multi-point fuel injection (MPFI) engines by manipulating the injection parameters through a programmable electronic control unit. In addition, tests are carried out using different generations of catalytic converters and checking that their working temperature is correct using a thermographic camera, verifying operation, to evaluate their effect on emission reduction. Detailed comparisons of the results between these configurations will allow the identification of the combination that reduces emissions the most without compromising engine efficiency and performance. This research aims to promote a more sustainable approach in the automotive sector by properly configuring systems, but also by demonstrating the technical robustness of their application in vehicles. It has also helped to verify that varying injection and ignition parameters help to fine-tune fuel injection, resulting in efficient combustion. Combining this variation with catalytic converters has further reduced exhaust pollutants.
