“…Renewable diesel fuels produce less particulate matter, carbon monoxide and total hydrocarbons due to reduced aromatics content, higher cetane number (HVO), or oxygen content (biodiesel); the same property, however, could lead to higher emissions of nitrogen oxides (NO x ) [3,4,5,6,7,8]. A disadvantage specific for biodiesel is its lower energy density, leading to a higher fuel consumption and a decrease in torque and power at full load conditions [9].…”

This study used toxicogenomics to identify the complex biological response of human lung BEAS-2B cells treated with organic components of particulate matter in the exhaust of a diesel engine. First, we characterized particles from standard diesel (B0), biodiesel (methylesters of rapeseed oil) in its neat form (B100) and 30% by volume blend with diesel fuel (B30), and neat hydrotreated vegetable oil (NEXBTL100). The concentration of polycyclic aromatic hydrocarbons (PAHs) and their derivatives in organic extracts was the lowest for NEXBTL100 and higher for biodiesel. We further analyzed global gene expression changes in BEAS-2B cells following 4 h and 24 h treatment with extracts. The concentrations of 50 µg extract/mL induced a similar molecular response. The common processes induced after 4 h treatment included antioxidant defense, metabolism of xenobiotics and lipids, suppression of pro-apoptotic stimuli, or induction of plasminogen activating cascade; 24 h treatment affected fewer processes, particularly those involved in detoxification of xenobiotics, including PAHs. The majority of distinctively deregulated genes detected after both 4 h and 24 h treatment were induced by NEXBTL100; the deregulated genes included, e.g., those involved in antioxidant defense and cell cycle regulation and proliferation. B100 extract, with the highest PAH concentrations, additionally affected several cell cycle regulatory genes and p38 signaling.

“…In regard to NO x emission, somehow contradictory conclusions were found, since there are numerous factors, each has its own relative importance according to the engine technology and operating conditions of the blended fuel [9][10][11][12][13]. Physical properties, chemical composition, and structure of the biodiesel alter the fuel injection and ignition process, and then the combustion development and the engine exhaust emissions [14][15][16][17][18].…”

Improvement Trends for Internal Combustion Engines

The employment of biofuels in blends with diesel oil proved to attain a reduced environmental impact without compromising the engine performance. Among biofuels, waste cooking oil offers the advantages of its reduced raw material cost in comparison with fresh vegetable oil cost; it also eliminates the environmental impacts caused by its disposal. Although a great number of researches has been devoted to biodiesel combustion in engines and pollutant emissions, few studies can be found on light duty diesel engine equipped with up-to-date technologies. This work aims at investigating the impact of waste cooking oil percentage in blends with diesel oil on the performance and emission characteristics of an up-to-date light and compact common rail diesel engine whose main application is in microcars and in urban vehicles. A comprehensive experimental activity was performed in the engine complete operative field. The comparison of the results with those obtained with standard ultralow-sulfur diesel highlighted that the engine performance was quite similar for B20 and diesel oil. B40 suffered for the lower caloric value in regard to diesel. A reduction in CO and HC was obtained with biodiesel blends, along with an increase in NO x . Particulate emissions were also reduced for biodiesel blends; the mean size of particles was smaller as regards diesel oil.

“…5,6 Most of the literature has reported that the inbuilt Oxygen in biodiesel and operating temperatures lead to increases in NOx. [7][8][9][10][11] A few researchers found the opposite trend. 12- 16 An H et al 17 also found there was a reduction in NOx with pure biodiesel, resulting to lower the heat release rate and cylinder pressure.…”

The purpose of this work is to investigate the influence of nano Aluminum Oxide nano on the performance and emission properties of a diesel engine operated with Jatropha methyl ester. The nano Aluminum Oxide was added to a blend of B10 such as 90% diesel + 10% Jatropha methyl ester. The JME was mixed with Aluminum Oxide particles using an ultrasonicator. It has been observed that, the Aluminum Oxide additive improves the brake thermal efficiency (BTE) and reduces consumption of fuel per unit output for almost at all tested loads. The Aluminum Oxide is good in regulating the hydrocarbon (HC), oxides of nitrogen (NOx), carbon monoxide (CO) and smoke.
