“…B100 biodiesel would have better performance at high loads. This behavior is probably due to the oxygenation of the molecule and the structural simplicity of its chemical composition [23][24][25][26]30]. At high temperatures, the relatively higher viscosity of biodiesel is no longer fundamentally a handicap for the combustion of this fuel.…”

This study presents an experimental investigation and thermodynamic 0D modeling of the combustion of a compression-ignition engine, fueled by an alternative fuel based on neem biodiesel (B100) as well as conventional diesel (D100). The study highlights the effects of the engine load at 50%, 75% and 100% and the influence of the heat loss models proposed by Woschni, Eichelberg and Hohenberg on the variation in the cylinder pressure. The study shows that the heat loss through the cylinder wall is more pronounced during diffusion combustion regardless of the nature of the fuels tested and the load range required. The cylinder pressures when using B100 estimated at 89 bars are relatively higher than when using D100, about 3.3% greater under the same experimental conditions. It is also observed that the problem of the high pressure associated with the use of biodiesels in engines can be solved by optimizing the ignition delay. The net heat release rate remains roughly the same when using D100 and B100 at 100% load. At low loads, the D100 heat release rate is higher than B100. The investigation shows how wall heat losses are more pronounced in the diffusion combustion phase, relative to the premix phase, by presenting variations in the curves.

“…Furthermore, there was a reduction in carbon dioxide (CO2) and nitrogen oxides (NOx). Furthermore, they discovered that 2-ethyl 1hexanol is a superior additive to pentanol since it emits less NOx, HC, and CO. (Mohamed, Tan et al 2020), explored the releases, Performance, and characteristics combustion of a biodiesel engine and its mixtures made from catalytic pyrolysis of waste vegetable oils in an experimental setting. The impacts of various catalyst types (sodium hydroxide vs. potassium hydroxide) have also been researched.…”

In this article, an investigational analysis has been conducted to explore the effect of biodiesel fuel blends on characteristics of engine and releases (CO2, CO, HCl, and NOx) of single-cylinder, four strokes at the variable biodiesel concentration. The releases of gases and the engine's characteristics were measured at six blending biofuels and six-speed conditions and constant load. The blending proportions of biodiesel with diesel fuel-based by volume were at 0% pure diesel, 5%, 10%, 15%, 20%, and 25%. This investigation aims to assess the biodiesel fuel mixture's impact on the CI engine performance in terms of its Bsfc, Ƞbth, and engine release of CO2, CO, HCl, and NOx. The investigation revealed that biodiesel remarkably minimized the release of CO2, CO, HCl, and NOx. The influence of this fuel mixture was studied between 5% to25% biodiesel concentration, and the results of this investigation could aid in understanding the Impact of utilizing biodiesel as an energy source on engine releases and performances.

“…Raheman and Phadatare [13] found a CO emission reduction of about 73-94% for Karanja Methyl Ester (B100) and its mixtures (B20, B40, B60, and B80) when compared with diesel fuel. Mohamed et al [14] reported that average HC emission reductions from the biodiesel fuel blends were only observed for blend ratios no higher than 40% for five different types of biodiesel compared with pure diesel fuel. Kale et al [15] proposed that microalgae biodiesel and its various diesel blends will be used as promising alternative fuels for diesel engines due to their advantages.…”

Fossil fuel is one of the sources leading to the increasing greenhouse gas that causes global warming. It is also seen that the volume of oil discovered worldwide every five years is decreasing. Finding ways to replace petrol-diesel with biodiesel for use in internal combustion engines to reduce CO2 and overcome the diminishing supply of crude oil has attracted many researchers. Viet Nam is a country known as one of the world's largest producers of catfish. We mix biodiesel produced from Vietnamese pangasius fish fat with petrol-diesel at four blend ratios of 0%, 20%, 40%, and 60% to produce samples labeled, B0, B20, B40, and B60, respectively. These biodiesel blends were then used to operate a petrol-diesel engine for experimental investigation. The results show that the torque and power would decrease as the biofuel ratio increased. However, the rate of decrease of these parameters did not exceed 16%, even when the ratio of biofuel in the biodiesel was up to 60%. The average power reduction of biodiesel blends was only about 8.70%. In terms of exhaust emissions, there was a significant reduction of CO, NOx, HC, CO2, and smoke opacity when biodiesel was used. The CO, CO2, and smoke opacity reduction was about 64.3%,15.1%, and 23.2% for the B60 fuel. In addition, the results also indicate that it is entirely possible to use biofuel produced from pangasius fish fat for internal combustion engines without changing the engine structure.
