Basic Characteristics

Biofuels derived from vegetable oils are known to be promising alternative fuels for diesel engines. The possibility of using mixtures of petroleum diesel fuel with rapeseed oil and rapeseed oil methyl ester as environmentally friendly motor fuels is considered. The practicability of changing the composition of these mixtures in accordance with the engine operating mode is shown. A technique for multicriteria optimization of the composition of such mixed biofuels is suggested. The basic characteristics of the optimal composition of these mixed biofuels are calculated. A device for regulating fuel’s composition is proposed. The basic characteristic of regulation of the blended biofuel composition realized by the device is presented.

: This paper presents the production of biodiesel from three different non edible oils of Pongamia, Mahua and Jatropha as an alternative fuel for diesel engine. Biodiesel is produced by followed transesterification process, using catalyst sodium hydroxide (NaOH) and methyl alcohol (CH3OH). A single cylinder four stroke three-wheeler auto diesel engine is used to evaluate the exhaust emission characteristics at a constant speed of 1500rpm with varying loads. Diesel as a reference fuel and cent percent of Pongamia Methyl Ester (PME), Mahua Methyl Ester (MME) and Jatropha Methyl Ester (JME) are used as an alternative fuel. The physicochemical properties of biodiesels are within the limits of international standards (ASTM D6751) noticeably. The results of tested biodiesels offer low exhaust emissions compared to diesel fuel, owing to presence of molecular oxygen and high cetane number. At maximum load the NOx emission reduced by 18.41% for JME, 17.46% for MME and 7.61% for PME. Low levels of CO emissions are recorded for JME (66%) followed by MME (33%) and PME (22%). Unburnt hydrocarbon emissions were reduced by 85.75% for JME and MME, for PME 14.28% reduction is observed. Exhaust smoke emissions are also reduced for PME and MME by 18.84%, for JME 14.49%. As a conclusion, it is observed that all the methyl esters exhibit significant reduction in harmful exhaust emissions compared to diesel fuel and JME is noted as a better choice.

This study presents an experimental and analytical investigation on the effects of using methyl ester of linseed oil (MELO)-diesel blend of B10, B20, and B30 with hydrogen injection of 5%, 10%, and 15% in a VCR (Variable Compression Ratio) diesel engine, operated with the compression ratios (CRs) of 15, 16, 17, and 18 on DFM (duel fuel mode). This study also gives emphasis on the optimized emissions of CO, CO2 , NO, and smoke, when the engine was operated with MELO-diesel blends, and hydrogen injections with the variation in engine load, crank angle (CA), using response surface methodology (RSM) with the help of MINITAB programming. During the analysis it was observed that the emissions of CO, CO2 , O2 , NO, and smoke were found to be a function of biodiesel blends, compression ratios, load, and percentage of hydrogen injection. The research results report that, the dual fuel mode of diesel MELO 20% blend with hydrogen injection of about 10% gave optimized results in terms of performance and exhaust emissions, while the optimized CR was 17. The engine was smoothly operated with B20-H10-CR17 over lower emissions compared to diesel, throughout the load spectrum.
