“…The differentiation of biodiesel grades, derived from different feedstocks, is frequently observed in accordance with the American Society for Testing and Materials (ASTM) fuel standard. The practice of incorporating biodiesel into mineral diesel is a commonly employed method for introducing biodiesel as a viable fuel for direct utilization in diesel engines [16,17]. The determination of the maximum proportion of biodiesel-pure diesel, as stipulated by the blended fuel standard, is contingent upon the properties of the biodiesel feedstock [18].…”

“…Furthermore, engine technical aspects such as compression ratio, air-fuel mixture methods, and cooling, and operating conditions, are all major influences on engine performance [63,64]. Recently, some innovative approaches and updated technology have been developed to enhance engine output power while reducing pollutant emissions [65][66][67]. Other measures, such as enhancing engine technical characteristics, injection strategy, and so on, have been employed alone or in combination with novel fuel compositions to optimize the combustion process and achieve the best efficiency [68,69].…”

The current investigation involved the implementation of a research experiment aimed at assessing the operational and emission attributes of a compression ignition direct injection engine comprising a single cylinder. The engine was fuelled with rice bran oil (RBO), and its performance was analysed under different engine loads. The performance metrics that were analysed included the brake specific fuel consumption BSFC), brake thermal efficiency (BTE), exhaust gas temperature (EGT), and cylinder pressure. The exhaust emission parameters that were investigated include carbon monoxide (CO), carbon dioxide (CO2), hydrocarbons (HC), and oxide of nitrogen (NOX). The study compares the results obtained from an experimental investigation involving different variants of rice bran oil (RBO50, RBO75, RBO100) with those obtained from a diesel engine (RBO00). The lowest BSFC obtained for RBO100 is around 0.29 kg/kWh at maximum load conditions (75 %), while the highest obtained for RBO00 is 0.33 kg/kWh. For all operations of diesel and RBO blends, it was discovered experimentally that the BSFC increases until 25 % of engine load and then starts to decline as the engine load is raised. At normal engine load circumstances, RBO75 has the highest thermal efficiency, while RBO00 has the lowest. The high EGT reading of RBO50 blends was due to the high calorific value (CV) of the fuel blends, which produced more heat per unit mass than RBO75 and RBO100. RBO75 achieved the highest cylinder pressure under both half and full load scenarios. RBO00 (pure diesel) achieved the lowest cylinder pressure under both half and full load scenarios. RBO outscored diesel in terms of efficiency of engine. The exhaust emission characteristics that were assessed included NOX, CO2, HC, and CO. The experimental outcomes of the study using rice bran oil-based fuels, specifically RBO50, RBO75, and RBO100, are being contrasted with those of diesel fuel (RBO00). The findings indicate that emissions of CO, CO2, HC, and NOX are lower when using RBO75 and RBO100 compared to diesel fuel. Furthermore, an analysis was conducted to determine the HC emissions of both RBO75 and RBO100 fuels at two distinct engine speeds, specifically 3500 rpm and 2000 rpm. The HC emission level for RBO75 was observed to be at its peak of 211 ppm when the engine speed reached 3500 rpm. The RBO50 fuel exhibits lower levels of CO emissions, measuring at 1.2% (3500 rpm) and 0.32% (2000 rpm). Similarly, CO2 emissions are also reduced with RBO50, measuring at 8.3% (3500 rpm) and 6.9% (2000 rpm). These exhaust emission reductions are observed when comparing RBO50 to diesel (RBO00) and other fuel mixtures, under a 75% load condition. Elevated levels of NOX emissions were detected in diesel fuel (RBO00) at concentrations of 499 ppm (3500 rpm) and 599 ppm (2000 rpm). In comparison to other fuels such as RBO50, RBO75, and RBO100, these higher NOX emissions were noted. In summary, the emission properties of RBO were shown to be superior to those of diesel fuel. The optimal blend for emissions reduction, including CO2, CO, NOX, and HC, was determined to be RBO50.

“…The latter factor is important in countries with high variability of weather conditions. On the other hand, biodiesel has long been considered a unique alternative fuel that can be used in a diesel engine with little or no modification [78]. Fuels in ICE, apart from their main function of providing energy, perform a lubricating function [23,71].…”

Road transport is one of the most important factors for the national economy due to its universality and comprehensive possibilities of transporting people and goods. Unfortunately, from the energy point of view, it is also the most cost-intensive and has a negative influence on the natural environment. For these reasons, issues related to limiting the use of conventional fuels are very important, which results in reducing emissions from this sector, as well as reducing transport costs. This article presents currently used energy sources for propulsion of road vehicles, including fossil and alternative fuels, gaseous fuels and other energy sources such as fuel cells. The following section presents technologies that allow to recover some of the energy lost in motor vehicles and internal combustion engines used for their propulsion. The principle of operation of these solutions, their structure and their main features are presented. The last part focuses on discussing and identifying the most universal technologies for energy harvesting in vehicles and showing further directions of energy development in the automotive sector.

“…According to the test created by (Zhang et al 2018), the biodiesel fuel's kinematic viscosity and ignition delay time (IDT) were significant determinants in the burning process. The performance and emissions indicators of a single-cylinder compression-ignition DI motor fed with mixed biodiesel at various motor speeds were examined in exploratory testing by (Norhafana et al 2019). Results indicated that while diesel fuel had superior exhaust gas emissions than biodiesel, the latter had poorer performance metrics.…”

Biodiesel is regarded as a clean fuel alternative to fossil diesel fuel for fewer pollutant emissions of internal combustion engines. The biodiesel type can be made from waste frying oil, thus it has to be done right. Waste vegetable oil can be provided for free or at a low cost by restaurants and food processors that often use frying oils. Animal fat is also available for free or for a nominal fee from grocery stores, restaurants, and butchers who use lots of fats in their cooking. The methyl ester of oleic acid methyl ester (OAME) biodiesel was produced from used vegetable oil using the transesterification process in order to compare the performance of the 67 kW KUBOTA tractor diesel engine when utilizing OAME and fossil diesel. OAME biofuel was used without being mixed. The engine's reliability metrics and important indicators, including the brake torque, indicated power, brake-specific fuel consumption (BSFC) and burn duration, were identified. Optimal implementation was met by fossil diesel and the tested characteristics were very close. The OAME biofuel performs better in terms of volumetric efficiency and duration of combustion than the conventional diesel. The decision to choose a specific biofuel that is produced from a particular source so largely hinges on its availability and economic feasibility wherever it is used.
