Depending on the heat content and compression ignition (CI) engine combustion, biodiesel is a viable substitute fuel. Biodiesel is an oxygenated, safe, sulfur-free, biodegradable, and renewable fuel. It may be utilized in CI engines in any combination with diesel fuel without requiring the engine to be significantly modified. Many research studies have been made with several biodiesels as diesel substitutes, including Pongamia pinnata, Jatropha curcas, Mangifera indica, and Madhuca longifolia. The topic of the current review is the potential of renewable fuels to outperform diesel fuel in terms of performance, combustion, and emission characteristics. In the present study, CI engines are fueled with biodiesels made from Man. indica, Mad. longifolia, and pongamia seed oil. Adopting low heat rejection (LHR) mode CI engines and adding an antioxidant agent in addition to the biodiesel blends may resolve the issue of these biodiesels’ poorer performance and increased NO emission. Both these additions may provide positive approaches in both performance and emission.

Pilot diesel ignition is an effective approach for achieving efficient and clean combustion of natural gas. In this study, a rapid compression and expansion machine (RCEM) was constructed for examining diesel-ignited premixed methane combustion. The effects of the methane equivalence ratio and pilot diesel mass on the combustion process of diesel-ignited premixed methane gas were investigated. The results show that the combustion process can be divided into two stages: diesel dominance and premixed methane combustion. An increase in the methane equivalence ratio inhibits diesel combustion, leading to delayed CA10 and OH radical generation. However, it enhances premixed methane flame propagation and improves the heat release rate, resulting in a shorter combustion duration. An increase in the pilot diesel mass contributes to a larger flame area and higher OH generation intensity in the ignition region; however, too large a diesel mass inhibits methane flame propagation towards the diesel nozzle due to an extended injection duration. In conclusion, a larger pilot diesel mass can achieve better overall combustion performance, but excessive amounts may be counterproductive.

With the rapid depletion of fossil-based fuels and the urgent need to mitigate global warming, the critical necessity for sustainable energy transitions and the development of viable alternatives to power our modern world has gained substantial attention in recent times. Transportation is one of the major industries in the world, where diesel plays a crucial operational role every day [1]. As of June 2023, global diesel consumption has reached 79,692.18 thousandkilolitres/month [2]. A practical and promising solution to the problems posed by conventional diesel consumption is diesel blending. This approach not only fosters the adoption of cleaner energy alternatives but also aligns with sustainability objectives [3,4].At the same time, methanol is a versatile and emerging fuel which can be made from both fossil-based and renewable sources. Its appeal as a fuel lies in its liquid state, facilitating easy transport and handling. Methanol is a promising candidate for diesel blending due to its high oxygen content, lower knocking tendency and lower emissions [5,6]. By promoting a blend of diesel with renewable and eco-friendly fuel sources, we pave the way towards a more sustainable, resilient, and environmentally conscious energy future. The objective of this study is to comprehensively analyse the performance and property profiles of diesel-methanol fuel blends.The study focuses on utilizing specific cosolvent components, namely 1-decanol, 1-dodecanol, and n-butanol, to achieve successful blending of diesel and methanol. A total of 12 novel combinations were systematically tested to determine optimal blend proportions, facilitated by the cosolvent and its combinations. The determination of the fuel blend ratios was accomplished through ternary phase mixing experiments. The 12 resulting diesel-methanol fuel blends were thoroughly characterized, encompassing key properties such as calorific value, density, kinematic viscosity, sulphur content, cetane index, flash point, and pour point. Comparative analyses were conducted against the properties of pure diesel, providing valuable insights into the blend compositions and their potential applications. The characterization of the diesel-methanol fuel blends revealed that, in the majority of cases, the blends met acceptable limits, signifying their potential suitability for use as diesel fuel.In regard to performance analysis of the diesel-methanol fuel blends, a 4-stroke, single-cylinder diesel engine was employed for this study, boasting a rated power of 3.5 kW at 1500 RPM. The investigation encompassed the evaluation of critical performance metrics: BTE (Brake Thermal Efficiency), BSFC (Brake Specific Fuel Consumption), and BP (Brake Power). Throughout the experimental phase, the engine was subjected to five distinct loading conditions: L1 (No load), L2 (25% load), L3 (50% load), L4 (75% load), and L5 (Full load), while maintaining a consistent engine speed of 1500 RPM and a compression ratio of 18:1. These conditions provided a comprehensive understanding of the engine...
