“…Research has led to the development of new combustion technologies, which are not only efficient but also environmentally friendly [5]. One of the working conditions for reducing emissions is to improve the system in technical ways, such as changing the compression ratio, high injection pressures, improved ignition systems, smaller engines, Miller cycle and low-carbon fuels [6]. This has led to different technologies and engine names depending on the type of injection, and cylinder layout, among others.…”

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.

“…Engine exhaust emissions and performance is greatly influenced by the head design of the nozzle and jet formation. The results reveal that the impact of head nozzle design on combustion stability, standard emissions formation, and particulates is less prominent in early injection timing as compared to late injection timings [ 33 ].…”
