“…This fact is attributed to lower carbon and higher oxygen content in butanol/diesel blends. Similar trends were also observed by few researchers (Rakopoulos et al, 2010;Doğan, 2011;Chen et al, 2013). Fig.…”

“…Shorter combustion duration shows that the combustion rate increased with butanol fraction in neat diesel due to the higher oxygen content in the fuel. During mixing controlled combustion phase, fuel-oxygen mixing rate dominates the combustion (Chen et al, 2013). Therefore higher oxygen content in the butanol blends will dominate and lead to shorter combustion duration.…”

In this study, combustion characteristics and nano-size soot particle emissions from a stationary conventional diesel engine have been experimentally investigated using butanol/diesel blends. Experiments were conducted on a single cylinder stationary diesel engine at a constant speed of 1500 rpm for neat diesel and butanol/diesel blends (i.e., 10%, 20% and 30% butanol on volume basis) at different engine loads. Piezoelectric pressure transducer installed in the engine combustion chamber was used for measuring cylinder pressure data. In-cylinder pressure data for 2000 consecutive engine cycles was recorded and averaged data was used for the analysis of combustion characteristics. Butanol/diesel blends show higher rate of heat release in comparison to neat diesel and heat release rate increases with butanol percentage in the blend. Opacity meter and exhaust particle sizer were used for analyzing smoke opacity, size and mass distributions of soot particles respectively at different engine operating conditions. Soot particle distribution from 5 nm to 1000 nm was recorded at each test condition. Results show that total particle concentration decreases with an increase in engine operating loads. It was found that butanol/diesel blends have lower total particulate concentration and the surface area.

“…Similarly, Liu et al (2012) reported decreased HC emissions by approximately 6.8-24%, when using varying amounts of waste cooking oil biodiesels as a result of improved combustion when using biodiesel. On a closer observation, when the butanol content is over 15%, a higher oxygen effect is dominated by the effect of high latent heat of the saturated butanol vapor pressure that results in a poor fuel-air mixing condition and retarded evaporation causing unstable flame and consequently inappropriate combustion conditions, hence incomplete combustion that favor increased HC emissions (Chen et al, 2013b).…”

The transport sector is a major consumer of fossil fuels especially petroleum diesel, which is used to power diesel engines used on-road and off-road in trucks, tractors, passenger cars as well as marine vessels. This is because the diesel engine offers various benefits compared to the spark ignition engine. The advantages include superior fuel efficiency, higher thermal efficiency, greater power output, better fuel saving, lower carbon dioxide (CO 2 ) emission, larger torque and greater durability. Conversely, the diesel engine is a major source of both criteria and non-criteria air pollutants, which contribute to the deteriorating air quality thereby putting the health of mankind at risk. The objective of this study was to investigate the performance of butanol-microalgae biodiesel-diesel blends in terms of energy performances and pollutants' emission reductions by comparing the brake specific fuel consumption (BSFC), brake thermal efficiency (BTE) and exhaust gases temperatures as well as the nitrogen oxides (NO x ), particulate matter (PM), polycyclic aromatic hydrocarbons (PAHs), carbon monoxide (CO) and hydrocarbons (HC) of various diesel blends and against the baseline performance of regular petroleum diesel. All diesel blends showed higher BSFCs and BTEs compared to regular petroleum diesel, whereby BT20W0.5 had the highest BSFC and BT15B2 had the best performance in terms of BTE. Among the diesel blends, only 2% microalgae added to diesel blends increased the NO x emissions by about 2%, while for the addition of 10-20% butanol fractions and 0.5% water fractions resulted in lower NO x emissions by about 12-28%, when compared to petroleum diesel. All the diesel blends considered in this study showed PM reductions ranging between 22.4% for B2 and 60.4% for BT15W0.5%, while reductions of PAH emissions were ranging from 6.5% for B2 to 22.76% for BT20W0.5. On the other hand, only the use of 2% microalgae biodiesel showed reductions in CO emissions of about 0.34% and 1.01% for B2 and BT20B2 blends, respectively, while other diesel blends showed increased CO emissions of about 1.72-2.94% in comparison to CO emissions of diesel fuel emissions. The addition of higher butanol fractions of 20% increased the HC emission factors by approximately 18% and 70%, while the HC emission factors for biodiesel, 10-15% butanol fractions and 0.5% water additions lead to reductions in emission by about 8-50%. According to the results of this study, more research is recommended on the economic potential of using of oxygenated additives in diesel engine especially water addition, higher alcohols and dieselhols blends to evaluate the possibility of synergetic properties of these kinds of fuels to achieve simultaneous reductions in the emissions of NO x , PM, CO, HC, PAHs and other persistent organic pollutants (POPs).

“…Fewer droplets existed near the sprayed liquid core where the effect of viscosity was important. Research by Chen et al [26] indicated that the production of CO, HC, and soot was lower when n-butanol was used in diesel engines compared with methanol and ethanol under the same conditions. The results of Yao [27],Şahin [28], and Yilmaz [29] indicate that the use of diesel-n-butanol blending fuels could decrease the soot and CO emissions of diesel engines significantly without deteriorating in fuel economy and NOx emissions.…”

Experimental Investigation on Effect of Wall Roughness and Lubricant Film on the Adhered Fuel Film of N-Butanol-Diesel Blends after Spray Impingement

Abstract:The effect of wall roughness with different lubricant film thicknesses on the characteristics of adhered fuel films of diesel-n-butanol blending fuels after spray impingement has been investigated. Four steel plates with different types of roughness (root mean square height-Sq) that were coated with different lubricant film thicknesses (h l ) were used as impinged walls. The experimental conditions included dry walls (h l = 0), semi-wetted walls (SWW) with different thin oil films (0 < h l /Sq < 1), and fully wetted walls (FWW) with a thick lubricant film (h l > Sq). The results indicate that the adhered fuel mass ratio (ε) of blended fuel with 25% n-butanol (B25) was higher than that of blended fuel with 15% n-butanol (B15) under the same conditions. ε increased with an increase in Sq on the dry walls, but, under SWW conditions, it decreased with an increase in oil film thickness. The fuel film morphology was almost unaffected by the change in Sq, but the results implied that the roughness parameter-Skewness (Ssk) exerted a greater impact. The mean thickness h a and accumulated diameter D l of the adhered fuel film increased with an increase in h l , but, under FWW conditions, the effect of the roughness on the adhered film's features was insignificant.
