“…96 The formation of NO x emissions is primarily attributed to the high temperatures generated within the combustion chamber of diesel engines. 97 Although there is approximately 78% nitrogen and 21% oxygen in the Earth's atmosphere, these two components do not react with each other in ordinary situations. 98 However, during the combustion process at temperatures exceeding 1700 K, nitrogen and oxygen molecules react in the combustion chamber to form nitrogen oxides.…”

Although diesel after-treatment techniques demonstrate a substantial decrease in tailpipe emissions, the primary goal continues to be attaining nearly zero emissions to comply with current regulatory requirements and foreseeable imminent rigorous regulations. To achieve this objective, engine combustion systems and fuel formulations require fine-tuning. Taking insights from the recent literature, this review examines various processes, including homogeneous in situ methods, the incorporation of fuel-borne catalysts, and the use of biofuels. Despite progress in in-cylinder pollution mitigation techniques like low-temperature combustion, which exhibits substantial reductions in oxides of nitrogen (NO x ) and soot emissions, it is crucial to consistently advance technology to conform to evolving emission regulations and environmental concerns. A discussion is presented regarding the advantages and disadvantages of the homogeneous charge compression ignition (HCCI) mode and their potential for the future, focusing on biodiesel-fueled HCCI engines. The review assesses the effectiveness of thermal management strategies and engine design modifications that extend the operational range of HCCI engines powered by biodiesel in light of the inherent limitation of a restricted engine operating range. The review critically examines the merits and demerits of biofuels and HCCI systems and provides an essential analysis of current after-treatment approaches. With an imperative focus, the primary aim of this review is to ascertain modern catalysts designed explicitly for use in contemporary combustion systems. An exhaustive examination of the progress made in diesel oxidation catalysts, selective catalytic reduction techniques, lean NO x traps, diesel particulate filters, and catalyst regeneration is presented. The concluding remarks analyze the catalytic characteristics necessary for smooth incorporation with modern technological developments in various combustion systems.

“…India will be on par with the United States, Europe, and other advanced automotive markets across the world as a result of this new emission standard. Figure 1 gives an elaborate analysis of how the EV industry experienced poor sales due to COVID-19 effects from the month of May to July 2021, and the industry rise up with market relaxations after the migration to BSVI standards [11,12]. It is observed that, for the transportation services only, a large lump sum of the amount is to be paid [13].…”

The automobile sector is a promising avenue for enhancing energy security, economic opportunity, and air quality in India. Before penetrating a large number of electric vehicles (EV) into the power grid, a thorough investigation and assessment of significant parameters are required, as additional nonlinear and EV loads are linked to the decentralized market. Many automobile companies have already invested in electric vehicle research; hence, a detailed analysis on range anxiety and grid connectivity concerns are the important factors affecting the future of the electric vehicle industry. In this paper, the initial review is about the decentralized market in India and sustainable aspects of electric mobility based on the Indian context, as it is a developing nation with an enormous resource and scope for EV markets. With recent literature from the last three years, the substantial constraints observed in benefits and challenges are reviewed. The financial stability aspects and the incentives to overcome the barriers to EV adoption are briefly discussed. From the review, it has come to the limelight that infrastructure availability, technology, load demand, and consumer behaviour are all major obstacles in the electric vehicle ecosystem. For the overall design and study of the vehicle to grid (V2G) infrastructure, this paper also provides insight into the representation of electric vehicles in different energy-efficient models and their categorization while connecting to the grid. The methodology adopted for energy-efficient models includes lifecycle emissions, economy, smart charging, real-time optimization, aggregated EV resource modelling, and a support vector machine (SVM)-based method. This paper gives a positive impact on EV fleet integration and electric mobility in general, as it critically reviews the influential parameters and challenges. This classification depends on crucial parameters that are at the frontline of EV grid integration research. This review is a solution to enhance grid stability in regard to new EV models. With the advanced electric motors development and renewed battery technology models, longer-distance automobiles are now available on the market. This paper investigates the constraints of EV grid integration and analyzes different EV models to ease the grid stability for a decentralized market.
