“…Fuel with lower viscosity improves the atomization process and enhances combustion efficiency and BTE. The obtained results agree with numerous other experimental works performed on alcohol/biodiesel/diesel blends (Senthilkumar et al 2018;Venu and Madhavan 2016;Siva et al 2018;Rajesh Kumar and Saravanan 2015). Figure 8 illustrates the change in BSFC for B10P90, B20P80, P100 and diesel.…”

This work examines the effect of butanol as an oxygenated additive to lower carbon monoxide, smoke, nitrogen oxide and hydrocarbon emissions and to improve the performance aspects of Calophyllum inophyllum (Punnai) biodiesel. Singlecylinder, oil-cooled compression ignition engines are employed in this work. Neat Punnai biodiesel (P100) is blended with butanol at 10% and 20% by volume and labelled as B10P90 and B20P80, respectively. Methanol and alkaline catalyst (KOH) were used for the transesterification process for biodiesel production. The transesterification technique yielded 88% biodiesel from raw Punnai oil. Engine tests resulted in lower CO, smoke, NO x and HC emissions when fuelled with both butanol blends when compared to P100. In addition, BSFC (brake-specific fuel consumption) reduced and BTE (brake thermal efficiency) increased with the inclusion of butanol blends (B10 and B20) to neat Punnai biodiesel.

“…Figure 8 depicts the variation of percentage of CO emission with increasing BP output for all the tested fuels and the graph conveys that CO emissions increased with increasing Brake load, but with a steep rise in 3.3-4.4 kW range. There are some research works in the literature whose results found in agreement with the case [40][41][42][43][44]. From the Fig.…”

This article examines the prospects of using toluene added cashew nut shell pyro oil–diesel blends as alternative fuels in CI engine. Effects of adding fixed proportion (by vol.) of toluene (TU) to various cashew nut shell pyro oil (CPO)–diesel (D) blends on the performance and exhaust emission characteristics of a direct injection, single cylinder, water cooled, naturally-aspirated, constant speed run, 4-stroke CI engine were investigated under varied brake power conditions. Tested fuels were neat diesel, CPOT5 (5% CPO + 5% TU + 90% D), CPOT10 (10% CPO + 5% TU + 85% D) and CPOT15 (15% CPO + 5% TU + 80% D). CPO was extracted through a lab-scale fast pyrolysis apparatus. Fuel samples were prepared and characterized according to ASTM standards. Owing to the features like low sensitivity, impressive anti pinging, etc., presence of toluene in an optimal CPO-diesel blend was expected to promote the engine characteristics. Set of experiments were conducted for each fuel mixture and the respective in-cylinder pressure, fuel consumption, exhaust emission levels, temperatures were recorded. At the rated power output condition, CPOT5 fuel had shown 1.67% increased brake thermal efficiency, 5% reduced brake specific fuel consumption, almost 3% reduced exhaust gas temperatures as well as reduced the exhaust emissions such as HC (from 91 to 87 ppm), CO (from 0.1 to 0.08%), NOx (from 458 to 426 ppm), smoke levels (from 72 to 69 BSN). CPOT5 showed improved combustion characteristics like reduced ignition delays and combustion durations, increased rates of cylinder pressure rise and heat release. However, overall attained improvements in the engine parameters were found to be not up to the mark which makes the chances of using CPOT5 as best alternative to diesel feeble. Article highlights The Cashew nut shells agro-waste is efficiently converted into an alternative fuel. Effect of adding toluene to pyro oil – diesel blends in CI engine is examined. Engine performance is improved marginally with 1.6% higher brake thermal efficiency (BTE) and 5% lower brake specific fuel consumption (BSFC). Reductions in CO, HC, NOx and smoke emissions are observed. Reduced Ignition delay and combustion durations, increased rate of pressure rise, and increased HRR are observed.

“…Referring to Figure 4, in general, the torques of diesel engine with B30 fuel were lower than the torque of diesel engines with pure diesel fuel. It was not surprising since biodiesel fuel had a lower heating value to diesel oil as reported by Abed et al (2018) and Siva et al (2019). This work revealed that the rising of transesterification temperature led to the higher torque of the diesel engine.…”

This study aimed to examine the effects of transesterification reaction temperature on the biodiesel properties and diesel engine performance. Biodiesel properties evaluated in this work included viscosity, density, and methyl ester content. Meanwhile, the diesel engine performance testing comprised the examination of the engine’s torque and power. The research was conducted in several stages, viz. producing biodiesel from fresh cooking oil with variations in transesterification temperature of 45℃, 55℃, and 65℃; testing the characteristics of biodiesel produced; blending biodiesel with petroleum diesel to result in B30 biodiesel fuel; and testing biodiesel fuel (B30) in diesel-engined vehicles. It was revealed that the higher transesterification temperature led to the lower biodiesel viscosity, the decreasing value of biodiesel density values, and the higher methyl ester content. Furthermore, it was also demonstrated that increase of the transesterification temperature resulted in the higher value of torque and power generated. However, compared to the petroleum diesel fuel (B0), biodiesel fuel (B30) exhibited the lower values of the engine’s torque and power. The highest average values of torque and power of B30 fueled diesel-engine were 108.11 Nm and 43.51 kW, respectively, provided by the biodiesel produced at the transesterification reaction temperature of 65℃.of 65℃.
