“…Cottonseed methyl ester-biodiesel was used in the current study, and it was prepared by the transesterification method. In this regard, the biodiesel production steps and rates were preferred in light of the literature studies which previously performed and achieved high performance [28,29]. Biodiesel production steps are given in Fig.…”

The purpose of this study is to investigate the impacts of diesel-biodiesel-alcohol blends on the combustion, performance and emissions characteristics of a single-cylinder diesel engine. Tests were conducted at different engine speeds of 1750, 2250, 2750 and 3250 rpm and under full load. In this study, different fuels [called as reference diesel (D100), 20 vol% cottonseed methyl ester (D80C20), 10 vol% ethanol (D90E10) and finally the ternary type of their derivations (D70C20E10)], were used. The experimental results showed that the highest reduction values were observed on CO emission by 42%, 30% and 8% for the D90E10, D70C20E10 and D80C20 fuels, respectively. These reductions for HC emission were achieved as 40%, 31% and 23% for the D90E10, D70C20E10 and D80C20, respectively. On the other hand, the reductions of NO x and CO 2 emissions were not sharp and varied between 2-7%. Besides the reductions on the exhaust emissions, biodiesel-ethanol blend presented better results in terms of HRR max and CP max than using biodiesel alone. Additionally, ignition delay of the biodiesel blends was longer than that of D100 fuel owing to their low cetane numbers. Combustion duration was shortened with the increment in engine speed because the turbulence increased in the combustion chamber at high engine speed. This case also improved the homogeneity of test fuels and increased the quality of the combustion process. As a consequence, this paper clearly reported that it is possible to achieve fewer emissions, the highest CP max values with the presence of ethanol in biodiesel fuels rather than using biodiesel alone for diesel engines.

This paper deals with the usability of sardine fish oil methyl ester doped with manganese based organic compound in diesel engines as an alternative fuel. For this purpose, raw sardine fish oil was obtained from sardine fish waste (fish heads, fish bones, and fish internal organs). A two-step catalytic process was performed to convert the raw sardine fish oil into methyl ester. Methanol, sulfuric acid and sodium hydroxide catalysts were used for the reaction. The quality of biodiesel produced in this study agrees with the Standard Specification for Biodiesel Fuel American Society for Testing and Materials (ASTM 6751). Smn50, Smn75, and Smn100 experimental fuels were obtained by mixing the obtained fish oil methyl ester into diesel fuel (DF) at 50%, 75%, and 100% by volume. Then, 12 ppm organic resin-based manganese (Mn) was added to each mixture. The obtained fuel mixtures were tested and compared with pure diesel fuel (DF) under full-load engine torque condition in terms of engine performance and emissions. The results show that the temperatures of exhaust and engine torque, power, NOx, CO2 decrease when Mn-added biodiesel blends are used on the engine. Compared to other fuel blends, the Smn50 fuel blend underwent the greatest reduction. In the Smn50 fuel mixture, on average, a decrease of 11.64% in torque, 11.16% in power, 10.06% in NOx, 1.25% in CO2, and 1.05% in exhaust gas temperature was observed. On the other hand, BSFC, HC, CO emission values were higher than diesel fuel. The least increase in these values was observed in the Smn50 fuel mixture. In Smn50 fuel, on average, the increase was 20.90% in BSFC, 4.22% in CO and 13.40% in HC.

In this study, the biodiesel obtained from the waste olive oil by transesterification method has been mixed with a 30% of diesel fuel as volume and tested with a single cylinder direct injection diesel engine. The main purpose of this study is to obtain purer biodiesel from waste olive oil using methyl alcohol (CH3OH) and sodium hydroxide (NaOH) as catalyst in the transesterification method and research performance, combustion and emission characteristics in detail in a direct injection diesel engine. The combustion, engine performance and exhaust emission values have been also compared with diesel fuel. The test engine was operated at a constant speed of 2200 rpm and different engine loads such as 3.25 Nm, 7.5 Nm, 11.25 Nm, 18.75 Nm. According to the experimental results, the thermal efficiency of biodiesel is lower by about 1% to 5% than diesel. CO is lower about 37.5 % with biodiesel than that of diesel at 18.75 Nm. CO2 is higher 41% with biodiesel than diesel at 11.25 Nm. NOx was measured 9.5% higher than diesel fuel at 18.75 Nm. Soot emissions decreased by 37.5% compared to diesel.
