“…For the pure biodiesel fuelling the ratio of CD to ID was 3.75 but in case of 45% of EF fraction this ratio was 1.32. Similar results are obtained by Tse et al [15]. It was due to two characteristic properties of EF.…”

“…They stated that ethanol causes higher peak in HRR, longer ignition delay. They also stated that ethanol causes shorten the combustion duration resulting in longer premixed and shorter diffusive combustion duration when compared with biodiesel [15]. The emphasis is also on the search for sources of alternative fuels for engines and improvement of combustion systems [16][17][18][19].…”

“…Biodiesel molecule has a polar end with affinity for ethanol, which is also polar in nature, thus, biodiesel can be used as an alternative stabilizer in preventing the separation of ethanol from diesel fuel [15]. Ethanol fuel as a fuel for compression ignition engine generally is used by blending with conventional diesel fuel or with using dual fuel technology [8,23].…”

Abstract. In the study are presented the results of co-combustion of biodiesel B100 with ethanol fuel as blend. The 1-cylinder direct injection compression ignition engine was used during the study. Tests were conducted at a constant angle of fuel injection and constant rotational speed equal to 1500 rpm. Results of thermal cycle parameters and emission characteristics are presented. On the basis of results stated that ethanol fuel fraction in blend causes the increase in peak heat release rate. With the increase in ethanol fuel fraction the ignition delay increased but combustion duration decreased. With the increase in ethanol fuel fraction in blend thermal efficiency increased as well. It also noticed almost constant emission of THC, the increase in NOx emissions and decrease emissions in CO and CO2.

“…Study also concluded that n-butanol was better alternative fuel for fumigation as compared to hydrous ethanol on the basis of performance characteristics. Tse et al (2015) experimentally investigated the trade-off between the particle mass and total particle number concentration and NO x emissions from an automotive diesel engine fueled with diesel, diesel-biodiesel-ethanol blends and biodiesel. Study shows lower particulate emission (both in terms of particle mass and particle number) found with dieselbiodiesel-ethanol blends.…”

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.

In this paper, a three‐dimensional simulation model of the engine cylinder is established using commercial simulation software AVL‐Fire, and the accuracy of the model is verified with experimental results. The effects of diesel/biodiesel/n‐butanol blends on diesel engine performance, and combustion and emissions characteristics were investigated by performing simulation operations on the model. The combustion process in the cylinder was simulated for 0%, 5%, 10%, 15%, and 20% of n‐butanol in the fuel mixture. The results showed that at 75% load, the brake thermal efficiency of D95N5, D90N10, D85N15, and D80N20 engines increased by 0.84%, 1.68%, 2.48%, and 3.19%, respectively, and soot emissions decreased by 2.76%, 5.52%, 8.25%, and 10.96%, respectively, compared with D100. However, the brake power of the engine was reduced, the brake ratio fuel consumption increased, and NOx emission increased. In addition, at all loads, soot and CO emissions decrease as the percentage of n‐butanol in the fuel mixture increases.
