“…130 Thus, a narrow achievable load range remains the primary limitation, even with a PCCI strategy. Solutions like multiple injections to reduce the PPRR, increased boost pressure, 131 high fuel injection pressures, 132 charge dilution using water vapor induction, 133 and fuel modifications using alternative fuels such as alcohols 126 are explored to extend the engine operating load range in PCCI mode. RCCI is a dual fuel LTC strategy in which fuel with a lower reactivity is premixed by port fuel injection, and a higher reactivity fuel is directly injected into the cylinder during the compression stroke.…”

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.

“…24 A part of the fuel mixture is delivered into the pre-mixing chamber via appropriate adaptations or injected in the intake port, while the remainder is supplied directly into the chamber by a standard fuel injector. 25 Despite the used proportion of EGR, PCCI supplied a stratification of the equivalency ratio. We noted in a previous study that the chemical reactivity of the in-cylinder charge must be adjusted simultaneously following the engine operation circumstances.…”
