“…The result indicated that higher BSFC was observed in biodiesel blends due to higher density and lower heating value of the biodiesel. Rai et al [205] used robusta methyl ester biodiesel and diesel blends to investigate the effect of CR, engine load, and biodiesel blend ratio (10%, 20%, 30%, and 40% v/v) on diesel engine combustion and performance. The result indicated that at the CR of 17, higher BSFC was observed in the biodiesel blends, and the BSFC will increase with the increase in the biodiesel ratio.…”

Due to the increasing air pollution from diesel engines and the shortage of conventional fossil fuels, many experimental and numerical types of research have been carried out and published in the literature over the past few decades to find a new, sustainable, and alternative fuels. Biodiesel is an appropriate alternate solution for diesel engines because it is renewable, non-toxic, and eco-friendly. According to the European Academies Science Advisory Council, biodiesel evolution is broadly classified into four generations. This paper provides a comprehensive review of the production, properties, combustion, performance, and emission characteristics of diesel engines using different generations of biodiesel as an alternative fuel to replace fossil-based diesel and summarizes the primary feedstocks and properties of different generations of biodiesel compared with diesel. The general impression is that the use of different generations of biodiesel decreased 30% CO, 50% HC, and 70% smoke emissions compared with diesel. Engine performance is slightly decreased by an average of 3.13%, 89.56%, and 11.98% for higher density, viscosity, and cetane, respectively, while having a 7.96% lower heating value compared with diesel. A certain ratio of biodiesel as fuel instead of fossil diesel combined with advanced after-treatment technology is the main trend of future diesel engine development.

“…This is because the considerably greater density, viscosity, cetane number, and boiling temperature of ternary blends have a key influence on rising HC emissions. Fuel with high density and viscosity experiences a restriction in the flow and forms droplets with greater mass and size [32]. The bigger fuel droplets take more time to evaporate, which affects the mixing process and thereby results in an improper mixture.…”

“…ID is the crank angle degree that distinguishes the beginnings of fuel injection from the beginning of combustion. The crank angle (CA) required reaching 5% cumulative heat release was determined using the heat release rate curve [50]. The fundamental factors responsible Study on the engine characteristics (CI) of using pumpkin-maize-blended biodiesel for the delay period are the fuel's physiochemical properties and operating conditions [28].…”

This paper focused on the engine characteristics of a diesel engine fuelled using ternary blends. Initially, pumpkin and maize biodiesel were mixed in a volume ratio of 50:50. With a constant 0.5% diethyl ether (DEE) content, the binary combination of pumpkin and maize biodiesel was mixed with diesel at proportions of 10:90, 20:80, 30:70, 40:60, and 50:50 by volume. The prepared ternary mixtures were evaluated at varying engine loads to improve engine performance. Compared to diesel, the tested ternary blends had a reduced brake thermal efficiency (BTE). However, up to a 30% blending ratio, the BTE demonstrated by ternary blends was within the range of less than 0.5% concerning diesel fuel. The ternary blends' BSFC declined as the binary biodiesel mix increased. Diesel has a brake specific fuel consumption (BSFC) of 1.4%, 2.2%, and 3.4% lower than the ternary blends of 10%, 20%, and 30%. The decrease in the heat release rate of the ternary mixes meant that emitted less CO and NOx than diesel. In contrast, ternary blends exhibited an increasing trend in smoke and HC emissions because of the rise in incomplete combustion that occurs as biodiesel content rises. Therefore, with appropriate engine modifications, the pumpkin and maize binary biodiesel blend can replace diesel by up to 30%.
