Emission Reductions of Nitrogen Oxides, Particulate Matter and Polycyclic Aromatic Hydrocarbons by Using Microalgae Biodiesel, Butanol and Water in Diesel Engine

摘要: The transport sector is a major consumer of fossil fuels especially petroleum diesel, which used to power diesel engines on-road and off-road in trucks, tractors, passenger cars as well marine vessels. This because the engine offers various benefits compared spark ignition engine. advantages include superior fuel efficiency, higher thermal greater output, better saving, lower carbon dioxide (CO2) emission, larger torque durability. Conversely, source both criteria non-criteria air pollutants, contribute deteriorating quality thereby putting health mankind at risk. objective this study was investigate performance butanol- microalgae biodiesel-diesel blends terms energy performances pollutants’ emission reductions by comparing brake specific consumption (BSFC), efficiency (BTE) exhaust gases temperatures nitrogen oxides (NOx), particulate matter (PM), polycyclic aromatic hydrocarbons (PAHs), monoxide (CO) (HC) against baseline regular diesel. All showed BSFCs BTEs whereby BT20W0.5 had highest BSFC BT15B2 best BTE. Among blends, only 2% added increased NOx emissions about 2%, while for addition 10–20% butanol fractions 0.5% water resulted 12–28%, when considered PM ranging between 22.4% B2 60.4% BT15W0.5%, PAH were from 6.5% 22.76% BT20W0.5. On other hand, use biodiesel CO 0.34% 1.01% BT20B2 respectively, 1.72–2.94% comparison emissions. 20% HC factors approximately 18% 70%, biodiesel, 10–15% additions lead 8–50%. According results study, more research recommended on economic potential using oxygenated additives addition, alcohols dieselhols evaluate possibility synergetic properties these kinds achieve simultaneous NOx, PM, CO, HC, PAHs persistent organic pollutants (POPs).
