“…At no-load conditions, the ID is higher for all fuels due to the availability of more time during the SOI and the SOC. If no EGR is admitted then there is a substantial reduction in the ID at all loads due to the replacement of air with EGR, which leads to a decrease of oxygen in the exhaust gases, the ignition delay period becomes longer and the combustion becomes slower (Girardi et al 2021). The ID for diesel and B20 biodiesel, is 17°CA and 16°CA respectively, at full load, whereas for B20 with 5%, 10% and 20% EGR is found to be 16.5°CA, 17.5°CA and 18°CA respectively.…”

Pollution from diesel engines affects negatively the environment. As a result, there is a worldwide concern about reducing the pollutants emitted by diesel engines. In comparison to diesel fuel, biodiesel combustion produces reduced carbon monoxide (CO2) and unburned hydrocarbon (UHC) emissions, but higher nitrogen oxides (NOx) emissions. The current study is to investigate the thermal and chemical effect of exhaust gas recirculation (EGR) on features of a diesel engine for environmental sustainability. The punnai oil was produced from kernels of punnai seeds and transesterified in two phases using alcohol with the existence of a catalyst. The higher viscosity of punnai oil biodiesel is diluted by mixing it with diesel fuel. Our previous investigation indicated that neat punnai oil biodiesel is a potential fuel; however, the findings showed that the addition of diesel is necessary to obtain acceptable engine performance. In this study, punnai oil biodiesel was mixed at a rate of 20% with diesel (B20) and run in a diesel engine with varied EGR rates under five different engine loads. This combined impact enhanced the maximum heat release rate (HRR) and maximum combustion pressure, according to the findings. The premixed burning fractions were commonly higher at all engine loads, whereas the diffusion combustion fractions were lower. When the centre of the HRR changed toward the top dead centre (TDC), combustion durations remained rather constant. The experimental results revealed B20 blend at 10% EGR flow rate produced 6.57% lower BTE, 37.04% higher BSEC, 2.47% higher EGT, 5.13% lower CO, 31.11% higher CO2, 3.13% higher UHC, 8.36% lower NOx and 4% higher smoke opacity when compared with diesel in a standard diesel engine.

“…Babassu (Attalea speciosa) Paiva et al [52] reported good biodiesel yields for babassu (Attalea speciosa) oil transesterification with ethanol using KOH or NaOH as catalyst either in a conventional magnetically stirred reactor or in another with ultrasound irradiation. Ferrari and Soler [53] synthesized biodiesel from the same oil with ethanol using sodium methoxide (NaOCH 3 ) as a catalyst, while, in a similar study, Girardi et al [54] also tested natural additives such as isoamyl alcohol, camphor and limonene to improve biodiesel production. Oliveira et al [55] first studied the effect of alcohol chain length from C1 to C8 on biodiesel production from babassu oil, and then, using ethanol, tested different catalysts such as KOH, H 2 SO 4 and p-toluenesulfonic acid to obtain ethyl esters.…”

Biofuels are increasingly important renewable resources in the world’s energy matrix that have challenged the scientific community as well as small and large farmers to develop alternatives to fossil fuels in order to achieve the aims of energy transition. In particular, Brazil’s proven competitiveness in agribusiness together with its rich biodiversity put the country in a key position in the biofuels market. The semiarid Caatinga of northeastern Brazil, an exclusive biome rich in many oilseed species suitable for potential energy purposes, is of particular interest in this field. Nowadays, soybeans are the main feedstock used for the production of biodiesel, but, due to the increasing demand for biofuels, the search for alternative sources of oil from tropical flora with high productivity is crucial. Under this premise, this systematic review focuses on mapping Caatinga’s vegetable oil crops that could be used as alternative raw materials for biofuels’ production in Brazil, in addition to traditional soybeans and sugarcane. To gain more detailed insight into these matrices, their main properties, including oil content, fatty acid profile and physicochemical properties, are discussed. Moreover, an overview is provided of processes to synthesize different types of biofuels, particularly biodiesel and aviation biokerosene, including the routes employing homogeneous, enzymatic and mainly heterogeneous catalysts. Finally, future prospects and challenges for renewable biofuels and the Caatinga biome are addressed.

“…In addition, fuel can be produced from palm fruit to power engines. Girardi et al, in their work, conclude that biodiesel from babassu has suitable physical and chemical properties and can become a commercial biofuel [39]. Ferreira et al pointed out the high potential of babassu oil production in Brazil and the possibility of using it for biodiesel production [40].…”

Progressive and increasingly noticeable climate change is forcing the search for new energy sources to reduce greenhouse gas emissions, especially carbon dioxide. One way to reduce greenhouse gas emissions is by gradually replacing fossil fuels with biofuels. The authors of this work addressed the production of second-generation biofuel. The purpose of this study was to produce second-generation biodiesel from babassu palm oil (BBuE) and first-generation biodiesel from rapeseed oil (RME), to study their properties, and to determine the effect of the addition of these biodiesels to diesel fuel on selected properties of “B” fuels that affect the fuel–air mixture formation process and the combustion process. Biodiesel from babassu oil was produced because it is non-edible and has a different composition than canola oil. Then, fuels were prepared that were mixtures of diesel oil and biodiesel containing from 10 to 40% (v/v) BBuE or RME (B10, B20, B30, and B40).Tests were conducted on selected physicochemical properties of the obtained fuels. “B” fuels prepared with BBuE and DF were shown to have more favorable fuel properties than those obtained from RME and DF. Fuels that are blends of BBuE and DF have slightly higher heating values, higher cetane number values, a more favorable distillation curve, lower dynamic viscosity values as a function of temperature, and marginally lower flash point values compared to the corresponding blends of RME and DF. Esters with shorter molecules have been shown to have more favorable fuel properties.
