Biodiesel is a clean, renewable, biodegradable, environmentally benign, energy efficient and diesel substituent fuel used in diesel engine. It provides a feasible solution to the twin crises of fossil fuel depletion and environmental pollution. It is produced from renewable sources such as vegetable oils or animal fats by trans-esterification. Although this fuel has gained worldwide recognition for many years, it is not being widely commercialized like petroleum diesel in the world, not widely produced and used especially in our country Ethiopia. Analysis of fatty acid methyl ester composition of the biodiesel produced from castor oil was done with the help of GC-MS and 8 fatty acid methyl esters were identified. Acid and base catalyzed methods were used in the synthesis of biodiesel from castor seed oil. In addition to this the variables that affect the amount of methyl ester yield were determined and an optimum of 96.7 % fatty acid methyl ester (FAME) conversion was obtained at a methanol to oil molar ratio of 6:1, 1.0 % mass NaOH, 65 °C reaction temperature and 3 hour reaction time. The energy content of the oil and biodiesel were 39 MJ/Kg and 40.7 MJ/ Kg respectively which is determined by bomb calorimeter. Other physicochemical properties of the biodiesel were determined and all these lie within the ASTM and EN biodiesel standards except kinematic viscosity. Therefore, castor seed oil methyl ester could be used as an alternative energy resource in diesel engine by blending with petroleum diesel.

The objective of present study is to evaluate the combustion, performance, and emission characteristics of refined biodiesel (biofuel) such as rubber seed oil methyl ester with the partial addition of n-butanol (butanol) in it in a single cylinder four stroke diesel engine operated at a constant speed of 1500 rpm. Various characteristics of butanol–rubber seed oil methyl ester blends with varying volume percentage of butanol such as 5, 10, 15, and 20 in butanol–rubber seed oil methyl ester blends were compared with the characteristics of neat rubber seed oil methyl ester (100%) and neat diesel (100%) at various load conditions on engine (such as 0%, 25%, 50%, 75%, and 100%) for the compression ratio 18. It is found that brake specific fuel consumption was increased by 17% with an increase in butanol content from 5% to 20% in butanol–rubber seed oil methyl ester blends at full load condition. Brake thermal efficiency was decreased by 14% with an increase in butanol content from 5% to 20% in butanol–rubber seed oil methyl ester blends at full load condition. Carbon monoxide and HC emissions were found to be negligible, i.e. less than 0.1% and 35 ppm, respectively, for all selected fuels. NOx emissions were decreased by 10% with an increase in butanol content from 5% to 20% in butanol–rubber seed oil methyl ester blends at full load condition. Various characteristics were compared for six fuels (neat rubber seed oil methyl ester, four renewable butanol–rubber seed oil methyl ester blends, and neat diesel) in order to finalize the promising alternate sustainable renewable fuel in place of shortly diminishing conventional diesel fuel in order to provide the solution for increase in demand and price of conventional fuel (diesel) for power generation and to reduce the serious issues concerned with environmental pollution due to usage of neat diesel.

The aim of current research effort is to evaluate the performance of much less utilized Argemone Mexicana seed oil methyl ester in single cylinder, water-cooled, 4-S diesel engine. The Argemone Mexicana is an agricultural weed, a plant of wasteland; its use led to the resource conservation. The methyl ester or biodiesel obtained by Argemone Mexicana seed oil is produced by the course of transesterification process. This process consists of pretreatment of vegetable oil with acid catalyst due to high FFA content followed by base catalyzed transesterification. The essential properties of transesterified Argemone Mexicana seed oil are tested and compared with natural diesel. The biodiesel blends with diesel in the combination of B10, B20, B30, B40 and B50 are utilized in a compression-ignition engine, its performance parameters are examined and compared with natural diesel. The lower blends of biodiesel exhibits similar characteristics to diesel without any modification in the design of engine. This experimental work testified that the blending of diesel with biodiesel obtained from Argemone Mexicana oil in diesel engine is a feasible alternative for depletion of petroleum diesel.
