“…Hydrogen (about 10%), oxygen and nitrogen can be found in smaller proportions. 7,26,27 Diesel particles consist of a carbonaceous material (soot: carbon core), generated during combustion, on which are adsorbed various organic species, consisting of molecules condensed, called SOF (Soluble Organic Fraction). 2,7,13 It contains unburned hydrocarbons, oxygenated derivatives (ketones, esters, aldehydes, lactones, ethers, organic acids) and polycyclic aromatic hydrocarbons (the famous PAHs) together with their nitrated and oxygenated derivatives, etc.…”

A pressurized liquid extraction (PLE) technique was evaluated in this study and optimized using response surface methodology (RSM) for the determination of polycyclic aromatic hydrocarbons and their nitro derivatives from diesel particulate matter. A central composite design (CCD) was applied for the study of three parameters (temperature, nature of solvent and static time) and the optimal conditions were determined for a time of 9 min and a temperature of 145 °C and dichloromethane as extraction solvent. With the GC/MS analytical technique, the limits of detection (LOD) obtained range from 0.3 to 1.5 µg.L-1 for PAHs and from 4.6 to 8 µg.L-1 for nitrated PAHs. Also, this method allowed excellent recoveries of NPAH adsorbed on diesel soot particles (R ≥ 90%) using a mixture of solvents (1% acetic acid in pyridine). The PLE process developed in this research is quantitative and reproducible while using much less solvent than conventional extraction methods.

The aim of this study is to investigate the post-injection flow interactive effects of atomized fuel blends from an injector system of known characteristics into a direct injection compression ignition engine combustion chamber and their outcomes. Attempts were made to link the interactive influence of blend mixture quality, effluence and consumption rate of fuel injection properties on frictional loss, heat liberation, combustion, and volumetric efficiency performance outcomes of the engine. This numerical–experimental dimension study began with computational fluid dynamics (CFD) prediction of fuel in-cylinder behavior between a 225° CA (crank angle) (45°ABDC—after bottom dead center) and 360°CA (0° BTDC—before top dead center) compression stroke elapsing into an expansion stroke. A Testo gas analyzer was used to determine the combustion efficiency. The experiments validated the CFD outcomes presented. Willans lines were applied on blends to compare piston frictional losses. A swirl prediction maximum peak of 0.027237 at 336.15 CA for pure diesel blend (D100) at 2,300 rpm and 0.066811 at 341.3 CA for pure biodiesel blend (B100) at 1,800 rpm aided the mixing quality. The instantaneous velocity on the sinusoidal profile and contour around the swirling peak crank angle revealed ignition activity resulting from high mixing quality. The engine possessed high-efficient fuel blends burning strength on a minimum of 54.5% at a higher flow rate. The engine speed and flow rate interaction on the heat liberation rate made a symmetric profile for D100 and B100. Engine energy loss on friction was minimal with D100 compared to B100 and 5% biodiesel to 95% diesel blend (B5).

“…One challenge associated with using biodiesel as a sole fuel is its potential impact on engine power output [7]. This reduction in power can be attributed to the lower calorific value of biodiesel [8,9] which affects the combustion process and can result in lower engine performance [10]. Another challenge is that biodiesel has a higher oxygen content compared to petroleum diesel, which can lead to increased carbon deposits on injectors and combustion chambers [7].…”

This research work investigates the effects of adding ethanol to biodiesel-diesel blends on the performance and emissions of a single-cylinder, four-stroke, air-cooled compression-ignition engine. The engine was half loaded within a speed range 1000-2500 rpm. Four different fuel blends are considered: B0 (no biodiesel or ethanol), B10 (10% biodiesel), B10E2.5 (10% biodiesel with 2.5% ethanol), and B10E5 (10% biodiesel with 5% ethanol). The findings show that adding biodiesel slightly affects the engine power at low and medium speeds but increases power by approximately 6% at high speeds. Ethanol addition has a more significant impact, with an increase in engine power of 16% at 1700 rpm and 13% at 2500 rpm for 2.5% and 5% ethanol blends, respectively. All blends show an increase in brake mean effective pressure (BMEP) compared to B0, with the maximum enhancement observed in B10 with an average increase of 13% across all speeds. Specific fuel consumption is reduced with both biodiesel and ethanol addition, with a slight advantage for biodiesel, particularly at low and medium speeds. Thermal efficiency shows a reverse behaviour, with a small negative impact of ethanol addition. Biodiesel addition significantly increases carbon monoxide (CO) emissions, reaching an average of 190% across all speeds. However, adding ethanol helps mitigate this increase, especially at low and medium speeds, with an average decrease of 32% for 2.5% ethanol blend compared to B0. Carbon dioxide (CO2) and nitrogen oxides (NOx) emissions are reduced with biodiesel addition, and further reduced with ethanol addition. Overall, CO2 and NOx emissions are reduced with both biodiesel and ethanol addition.
