“…A higher CN generally indicates shorter ignition delay and earlier combustion, which helps the engine run smoothly. Conversely, a lower CN results in delayed ignition and increased HC and PM emissions [152]. According to the CN shown in Table 6, all third-generation biodiesel except waste fish oil-based biodiesel met the ASTM D6751 CN standard.…”

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 research aims to utilize the energy available from fish canning waste (FCW) as a partial alternative. The fuel is chemically modified to fish canning waste methyl ester (FCWME) by acid‐catalytic transesterification process and blended with diesel at 10%, 20% and 30% volume. The engine utilized in this study is slightly modified by engaging exhaust gas recirculation (EGR) to lower the nitrous oxide (NO) emission of oxygen‐rich fuel blends. Performance tests demonstrated that the FCW/diesel blends show similar patterns to diesel. Higher fuel consumption of 0.01, 0.03 and 0.04 kg/kWh was noted by including FCWME by 10%, 20% and 30% by volume. Power losses of about 1.4%, 1.9% and 2.1% were experienced by blending 10%, 20% and 30% volumes of FCWME with diesel. Conversely, the tailpipe emissions, namely smoke, CO and HC emissions, lowered by 3.7%, 0.017% and 21 ppm, with 117 ppm elevated NO emissions for the FCWME/diesel blends than diesel. The test results revealed that the NO emissions from all test fuels lowered drastically during 10%–30% EGR; 91 ppm reduction in NO emissions was observed at a 30% EGR rate, with a slight increase in other regulated emissions. Considering the encouraging impacts on the environment and improved fuel combustion pattern, FCW biofuel shall be employed as a likely and fractional alternative to diesel fuel.

“…9 that the higher the CN, the smaller the NO x emission. Several studies reported the effect of CN on resulting emissions and concluded that NO x decreased when CN increased in diesel fuel (Chacko et al, 2021;Kumar et al, 2019;Labeckas et al, 2021).…”

The performance and emission of a small diesel engine fuelled by commercial diesel fuel in Indonesia are present in this paper. Various commercial diesel fuels in Indonesia are produced and marketed by Pertamina. As the largest oil company in Indonesia, Pertamina has developed various diesel fuels, namely Solar, Biosolar (B30), Dexlite, and Pertadex. This study explains in more detail the performance, fuel consumption, and emission produced by the four types of fuels, and they were investigated experimentally using a single-cylinder diesel engine at various engine speeds, from 1,000 rpm to 4,500 rpm. The result shows the engine fuelled by Pertadex generates the highest power and torque, while the lowest is generated by the Biosolar fuelled engine. The maximum torque and power generated by the Pertadex fuelled engine are about 25.5 Nm and 7200 W, respectively. The engine fuelled by Pertadex has the lowest brake specific fuel consumption (BSFC) of 0.3037 kg·kW·h, compared to the engines fuelled by the Dexlite, Solar, and Biosolar fuels, with values around 0.3127, 0.3215, and 0.3338 kg·kW·h, respectively. At the same time, the measurement of gas emissions, including CO2, CO, NOx, and HC was conducted simultaneously.
