“…Many studies have been carried out on biodiesels and their blends with mineral diesel (Alptekin, Canakci, Ozsezen, Turkcan, & Sanli, 2015;Amid et al, 2020;Debnath, Sahoo, & Saha, 2013;Dharma, Ong, Masjuki, Sebayang, & Silitonga, 2016;Najafi, 2018;Sharma Dugala, Singh Goindi, & Sharma, 2020;Verma et al, 2020). The use of vegetable oil results in increased fuel consumption i.e., increased brake specific fuel consumption (BSFC).…”

An experimental study has been done to examine the performance and emission of a diesel engine using different blend ratios of Jatropha oil methyl ester at different engine speeds. At each speed, the engine was operated at no load, quarter, half, three quarters, and full load for different blending ratios. The performance parameters evaluated include Brake Power (BP), Brake Mean Effective Pressure (BMEP), brake specific fuel consumption (BSFC), air to fuel ratio (AFR), excess air factor, brake thermal efficiency, volumetric efficiency and the temperature of exhaust gas whereas exhaust emissions include specific emissions of O2, CO, CO2, and NOx. Biodiesel blends result in a decrease of brake power by 30.8 %, decreases in air to fuel ratio by 18 %, decreases in brake thermal efficiency by 21 %, decreases in volumetric efficiency by 10.7 % and increases in brake specific fuel consumption by 32.18 %. Specific emission of O2, CO, and NOx increases with increasing the percentage of biodiesel in fuel blends. Specific emission of CO2 decreases with increasing the rate of biodiesel in fuel blends. The results suggest that biodiesel obtained from non-edible oil like Jatropha could be a decent substitute to diesel fuel in the diesel engine.

Investigation of the Influence of Different Vegetable Oils as a Component of Blended Biofuel on Performance and Emission Characteristics of a Diesel Engine for Agricultural Machinery and Commercial Vehicles

Biofuels derived from renewable plant materials are considered promising alternative fuels to decrease emissions of ICEs. This study aimed to justify the possibility of using vegetable oils of different sources as a 10% additive in blended biofuel for diesel engines of agricultural machinery and commercial vehicles. Seven different vegetable oils were investigated. Experiments have been performed by fueling a diesel engine with blended biofuels of 90% petroleum diesel fuel and 10% vegetable oil. In the maximum power and maximum torque modes, the brake power drop was no more than 1.5%, and the brake-specific fuel consumption increase was less than 4.3%; NOx emissions were reduced by up to 8.3%, exhaust smoke—up to 37.5%, CO—up to 20.0%, and unburned HC—up to 27.9%. In the operating modes of the European 13-mode steady-state test cycle, the integral specific emissions of HC decreased by up to 30.0%, integral specific emissions of CO—up to 15.0%, and integral specific emissions of NOx—up to 16.0%. The results obtained show the feasibility and rationality of using the investigated vegetable oils as a 10% additive in blended biofuel for diesel engines of agricultural machinery and commercial vehicles.

The present work discusses the performance and emissions characterization of dual biodiesel sample blends on a varying compression ratio diesel engine. The dual biodiesel blends were obtained by blending two biodiesels (Mahua and Jatropha) in equal proportions volume (1:1, v/v) with mineral diesel. The sample blends were obtained on a ‘percentage by volume’ basis and named B10, B20, B30, and B40 (B10 was a blend of 5% each biodiesel with 90% mineral diesel and similarly for all other sample blends). All the experiments were performed at a constant engine speed of 1500 rpm, 50% loading conditions (2.6 kW), and varying compression ratios of 13.5:1, 14.5:1, 15.5:1, and 16.5:1. The results revealed that the sample blends had slightly higher brake power and mechanical efficiency with sample blends B10 to B40 had (0.15–1.58%) higher brake power and (1.07–12.42%) higher mechanical efficiency as compared to mineral diesel at a compression ratio of 16.5:1. The In-cylinder peak pressure and exhaust gas temperature were observed to be lower than mineral diesel for the sample blends B10 to B40 by 0.15–0.36 bar and 11.1–69.8 ℃, respectively. Also, the emissions of carbon monoxide and hydrocarbons were lower by 33–62%, respectively, for the sample with the highest blend percentage. However, the carbon dioxide emissions were found to be higher by 42.85% than mineral diesel. From the overall performance and characterization, it is concluded that B20 had optimum properties and blend percentage to be a better substitute fuel for mineral diesel among all the tested samples.
