Opis:
The influence of oxygenated diesel fuel containing n-butanol on a passenger car exhaust emissions was tested over the NEDC transient cycle. The tests showed that a diesel fuel/butanol blend, containing 10% of n-butanol, caused a significant decrease in PM and smoke emissions, had no effect on NOx and CO2 emissions and brought about higher CO and HC emissions. The most favourable fact resulting from the butanol application as diesel fuel component is that it produces desirable changes in PM/NOx trade-off.

2-Hydroxy-1-Naphthalene carboxaldehyde phenyl hydrazine
Opis:
A spectrophotometric method has been developed for the determination of Cu(II) using 2-Hydroxy-1-Naphthalene carboxaldehyde phenyl hydrazone as an extractive reagent. The reagent forms a coloured complex, which has been quantitatively extracted into n-butanol at pH 9.2. The method obeys Beer’s law over arrange from 1 to 10 ppm. The Molar absorptivity and Sandell’s sensitivity were 0.97 × 104 L mol-1cm-1 and 0.26 μg•cm-2 respectively. The proposed method is very sensitive and selective. The method has been successfully applied to synthetic and commercial samples.

Opis:
The article deals with the effects made by using various n-butanol-diesel fuel blends on the combustion history, engine performance and exhaust emissions of a turbocharged four-stroke, four-cylinder, CRDI 1154HP (85 kW) diesel engine. At first, load characteristics were taken when running an engine with normal diesel fuel (DF) to have ‘baseline’ parameters at the two ranges of speed of 1800 and 2500 rpm. Four a fossil diesel (class 1) and normal butanol (n-butanol) fuel blends possessing 1 wt%, 2 wt%, 3 wt%, and 4 wt% (by mass) of n-butanol-bound oxygen fractions were prepared by pouring 4.65 wt% (BD1), 9.30 wt% (BD2), 13.95 wt% (BD3), and 18.65 wt% (BD4) n-butanol to diesel fuel. Then, load characteristics were taken when an engine with n-butanol-oxygenated fuel blends at the same speeds. Analysis of the changes occurred in the autoignition delay, combustion history, the cycle-to-cycle variation, engine efficiency, smoke, and exhaust emissions NOx, CO, THC obtained with purposely designed fuel blends was performed on comparative bases with the corresponding values measured with ‘baseline’ diesel fuel to reveal the potential developing trends.

Opis:
The use of renewable fuels may be an action leading to the reduction of pollutant emissions. This group includes biobutanol as a product of biomass fermentation. Some of its physicochemical properties, including the ability to mix with hydrocarbon fuels, make it suitable for use as a fuel component for marine diesel engines. The article presents the results of research on the concentration of exhaust gas components of a Sulzer 6AL20/24 diesel engine powered by a mixture of n-butane and diesel oil. The emission intensity were calculated for the tested components: carbon monoxide, carbon dioxide and nitrogen oxides. The emission intensity surface graphs were created based on the calculated data. The tests were carried out using different concentrations of the mixture of n-butanol and marine fuel.

Opis:
The paper presents the experimental test results reflecting the comparative changes in the performance efficiency and emissions of the exhaust of a naturally aspirated, four-stroke, single-cylinder, air-cooled diesel engine due to its transition from neat rapeseed oil biodiesel to fuel blends prepared by mixing in various proportion (by volume) rapeseed methyl ester (B) and butanol (Bu). The lubricity properties of biodiesel-n-butanol fuel blends were studied using HFRR method. In contrast to previous works, the undertaken investigation is performed with a totally renewable, binary liquid biofuel blends. The purpose of the research is to reduce simultaneously the production of NOx emissions and the exhaust smoke with respect to neat biodiesel due to potentially improved homogeneity of combustible mixture and particulate matter emissions benefits suggested by the higher oxygen content (21.62 wt%) and the relatively lower carbon-to-hydrogen ratio (4.8) of the normal n-butanol. The tests revealed that the brake specific fuel consumption for the binary biodiesel-n-butanol fuel blends is always higher than that neat biodiesel produces under the same loading conditions. Maximum nitrogen oxide (NOx) emissions were obtained with the engine running on neat biodiesel (2290 ppm). At full (100%) load conditions, the lowest NOx emission was obtained with the engine running on a biofuel BBu20 blend. The lowest level of carbon monoxide emissions (CO) was observed, when engine running with the most butanol-oxygenated biofuel blend BBu20.The highest smoke opacity of the exhaust was obtained when the engine was fuelled with neat biodiesel and at full load.
