Abstract-The need of various transportation systems is increasing every day in such a fast developing world, and in the result of this, several vehicles and engine are increasing while conventional fuel like diesel and petrol are vanishing gradually with time. So it is need of the hour, we must have the alternative to above conventional fuels. The purpose of this experimental investigation is to study the effect of the blend kerosene oil blend together with conventional fuel on single cylinder diesel engine which is attached with eddy current dynamometer. An experimental analysis was made to check the diesel engine performance using various blends of kerosene with mineral diesel. Different blends of kerosene oil together with diesel in the ratio of 5%, 10% and 15% by volume and investigated under the different load conditions in a CI engine. The outcomes under various parameters were believed to be almost near to that of diesel fuel only. Different engine parameters such as brake power, brake specific fuel consumption, brake mean effective pressure, fuel consumption rate, exhaust gas temperature etc. have been determined and these were compared with diesel fuel.

The Taguchi technique has been used in this study to optimise the production parameters of biodiesel made from Argemone mexicana seed oil for maximum yield. This biodiesel has been produced through the transesterification process of non-edible vegetable oil of Argemone mexicana seeds. The molar ratio (A), Catalyst concentration (B), and reaction time or heating time (C) were chosen as the three factors that have a substantial impact on biodiesel production. All three factors are considered at three levels for experimental runs according to the L9 orthogonal array. The Biodiesel yield percentage was then measured for every experimental run. The signal to noise ratio has been calculated using the statistical software Minitab, based on the larger is better criterion. After analysing the Taguchi response table, the optimum level of all the parameters has been found out. The ANOVA technique was also applied to get the most significant factors that affect the biodiesel yield by calculating the percentage contribution of each factor. According to our results, the best combination of all the factors for Biodiesel yield is A3B3C1. The utmost and least influencing factors for Biodiesel production were heating time and molar ratio, with their contribution factors of 57.31% and 10.96%, respectively. Thus, the order of credence of all the three factors was CBA.

 Abstract: 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.
