“…Then, the peak pressure is 40.5, 40.24, 41.06, 40.80, 41.25, and 39.43, corresponding to diesel, B10, B20, B50, B75, and B100, respectively, and it happens by the consequence of cetane number, which is higher and very close to diesel, so that the blends B20, B50, and B75 showed higher cylinder pressure. Devan and Mahalakshmi [21] and Gad et al [26] noticed a similar kind of cylinder pressure behavior.…”

“…The slight alters in DE for raw vegetable oil and the higher emission induced [25] when NO x reduced. Recently, researchers concentrate on biofuel extraction from various natural resources such as Jatropha seeds [26], cashew nut [27], and deoxygenated vegetable oils [28]. Also, the researchers used several vegetable seeds for producing biodiesel and carried out their research experiments on that fuel.…”

This present work focused on investigating the thermal behavior and emission level of sapodilla oil mixed with diesel to an internal combustion (IC) engine. The behavior of the engine is measured via brake thermal efficiency (BTE), brake-specific energy consumption (BSEC), heat release rate (HRR), cylinder pressure, and cumulative heat release rate (CHRR). The test results were evaluated with diesel fuel. Carbon deposits were low in sapodilla seed oil with slight variation of calorific value than standard diesel fuel. BTE value for case B20 is found to equal diesel fuel. For lower and higher blends, the cylinder pressures are lower than the diesel fuel. HRR decreased as increased of the blend ratio. Inferior blends of sapodilla are emitted lower HC and CO. The BTE of B100 works 88.13% efficiently, similar to diesel for low load conditions. When compared to diesel, a maximum NOx reduction of up to 30% was achieved while using the sapodilla blend. It is found that the oil derived from the sapodilla seed kernels will be the promising additive for fossil fuels for a greener environment.

“…The analysis of the direct effects on the engine inherent in the consumption of biofuels has been the object of study for several researchers and the present report also focuses on this matter. Gad et al [6], when testing a diesel engine with fuel blends from Jatropha oil, achieve power and torque reductions at the engine's output by increasing the percentage of biodiesel in the mix. Additionally, the average effective pressure, thermal efficiency, volumetric efficiency, CO, and smoke emissions were reduced in these conditions.…”

The use of biofuels in vehicles becomes more advantageous than the consumption of fossil fuels, mainly because it uses renewable sources of energy. Recently there are some concerns about biodiesel sources, and hydrotreated vegetable oils (HVO) appear as a possible advanced solution. To understand the effect that the implementation of the new and old European type-approval test cycles (NEDC e WLTP) has on the results of these fuels considering pollutant emissions and fuel consumption results, a EURO V vehicle was subject to these cycles and also to engine performance evaluation tests. For this analysis, the fuels considered were: B0 (pure diesel), B7 (7% of biodiesel), B15 (15% of biodiesel), B100 (pure biodiesel), and HVO15 (15% of HVO). The findings lead to the conclusion that completely replacing fossil fuels with biofuels is not the most cost-effective approach. No significant differences were observed considering the two homologation cycles, the oldest (NEDC) and the actual (WLTP) and the use of HVO also does not present any relevant differences concerning the fuel consumption differences to B0 (+0.58% NEDC and +0.05%WLTP), comparing well with biodiesel behavior (−1.74% NEDC and −0.69%WLTP for B7 and +1.48% NEDC and 1.89% WLTP for B15). Considering the power of the engine obtained with the fuels, the differences are almost negligible, revealing variations smaller than 2% for B7, B15, and HVO15.

“…At the same time, emissions such as hydrocarbons (HC), carbon monoxide (CO), and particulate matter (PM) are significantly reduced in the absence [19]. With the intensive research on biodiesel fuels, it was found that biodiesel such as rapeseed methyl ester [20], jatropha seeds [21], rapeseed methyl ester [22], and sunflower methyl ester can be blended with diesel in different ratios to obtain better emission and combustion performance [23].…”

How to improve the combustion efficiency and reduce harmful emissions has been a hot research topic in the engine field and related disciplines. Researchers have found that nano-additives to diesel-biodiesel fuel blends have achieved significant results. Many research results and both current and previous studies on nanoparticles have shown that nano-additives play an essential role in improving the performance of internal combustion engines and reducing the emission of harmful substances. This paper summarizes the recent research progress of nanoparticles as additives for diesel-biodiesel fuel blends. Firstly, the excellent properties of nanoparticles are described in detail, and the preparation methods are summarized and discussed. Secondly, the effects of several commonly used nanoparticles as diesel-biodiesel fuel blends on combustion performance and harmful substances emissions in terms of combustion thermal efficiency, brake specific fuel consumption, CO, UHC and NOx, are reviewed. Finally, the effects of nano-additives on internal combustion engines, the environment and human health are discussed. The work carried out in this paper can effectively contribute to the application of nanomaterials in the fuel field. Based on our work, the researchers can efficiently select suitable nano-additives that enable internal combustion engines to achieve efficient combustion and low-emission characteristics.
