“…Fuel properties play a crucial role in the determination of the quality of fuel blending and the combustion process. Researchers often highlight properties such as calorific value, viscosity, flash point and cetane number to describe the effects of biofuel additives on the combustion process, performance, and emission characteristics of a diesel engine [30,31].…”

The production of biofuel from olive mill wastewater (OMWW) may be one of the promising techniques for use in diesel engines. In this study, biofuel was produced from the hydrothermal liquefaction of OMWW using a methanol-water co-solvent. Biofuel blends of 10% (B10), 20% (B20) and 30% (B30) by volume of biofuel, were prepared. The chemical and physical properties of biofuel blends are mostly similar to those of conventional diesel fuel. The engine speed was kept constant (1500 rpm) throughout the tests under different engine loads (25, 50, 75 and 100%). The effects of biofuel-diesel blends on exhaust emissions and engine performance were investigated. The results show that the in-cylinder pressure follows almost the same trend for all fuels. However, at high loads, with increasing biofuel blend, the combustion duration tends to become longer. The B10 blend provided close results to diesel fuel in terms of performance and polluting emissions. Moreover, the use of B10 resulted in reduced emission levels, with 11% of unburned hydrocarbons, 12% of particles and 26% of carbon dioxide compared to the other blends.

“…The characteristics of particulate matter can change when biodiesel and ethanol are added to diesel, and ethanol has a higher influence on these changes than biodiesel [232]. PM from DB10 (90% diesel + 10% biodiesel) vehicles reduced RAW 264.7 macrophage death (−60.8%) compared to PM from pure diesel (D100) vehicles, while PM from DE10 (90% diesel + 9% ethanol + 1% biodiesel) vehicles increased cell death (84.1%) [232]. This suggests that alcohol blends may be more immunotoxic than biodiesel blends.…”

The use of zero-carbon and carbon-neutral fuels reduces emissions of conventional pollutants, but their emissions can be toxic and have various adverse effects on human health. This article reviews the possible combustion products of zero-carbon and carbon-neutral fuels, as well as their cytotoxic effects and potential health risks. At the same time, the review outlines biological models and toxicity detection methods commonly used in pollutant toxicity studies. Metals, nitrogen oxides (NOX), and ammonia (NH3) emitted from the combustion of metal fuels, hydrogen fuels, and ammonia fuels in zero-carbon fuels are harmful to human health. Exhaust emissions from carbon-neutral fuels, particularly biodiesel, and their blends with gasoline/diesel are cytotoxic, leading to severe cellular damage, such as oxidative damage, inflammatory responses, DNA damage, cell death, or apoptosis. Moreover, the normal function of the human body’s respiratory, cardiovascular, immune, digestive, urinary, and nervous systems may also be impacted by these fuel emissions according to cytotoxic research. Cytotoxicity of fuel combustion products is usually related to the fuel type, time, dose, and cell line used in the experiment. This review provides some ideas for the exhaust emission management of zero-carbon and carbon-neutral fuels and human health assessment. It also presents a theoretical and experimental basis for further research, including in vivo experiments.

“…18 Previous studies showed that engine operating conditions (such as engine speed and load 19 and fuel injection strategies, 20,21 etc. ), fuel properties, [22][23][24][25] aertreatments, 26,27 and combustion mode 28,29 have a great inuence on soot formation and hence soot properties. It is thought that soot properties from diesel/methanol dual-fuel combustion can be changed since premixing methanol alters the in-cylinder combustion process and thus soot formation.…”
