Abstract: Biodiesel obtained from various renewable
emission parameters like brake power (BP), brake specific fuel consumption(BSFC), Brake thermal efficiency (BTE), CO emissions, CO2 emissions, HC emissions, NOx emissions and smoke were evaluated at different loads in a 4 stroke, single cylinder Diesel engine. These performance and emission parameters of diesel fuel were compared with that of B25, B50, B75 and B100. Key Words: Biodiesel, Alternate fuel, Trans esterification, Performance, Emissions, Linseed oil.
sources has been recognized as one of the alternative fuel due to its biodegradability, high cetane number, no sulphur emissions and low volatility. Biodiesel derived from non-edible feed stocks such as linseed oil are reported to be feasible choices for developing countries including India where consumption and cost of edible oil is very high .The aim of present work is to optimize the biodiesel production from linseed oil through trans esterification process. The various performance and

2. Production of Biodiesel From Linseed Oil
Due to scarcity and increasing costs of conventional fossil fuels, biodiesel as a fuel has become more attractive fuel. Experts suggested that current oil and gas reserves would tend to last only for few decades. To fulfill the rising energy demand and replace reducing oil reserves renewable fuel like biodiesel is within the forefront of other technologies. Biodiesel has proved to be a possible alternative for diesel in compression ignition engine. Biodiesel burns like petroleum diesel as it involves regulated pollutants. Diesel fuel can be replaced by biodiesel made from vegetable oils. Biodiesel is now mainly being produced from soybean, rapeseed, and palm oils. In developed countries, there is a growing trend toward using modern technologies and efficient bio-energy conversion using a range of biofuels, which are becoming cost wise competitive with fossil fuels. India enjoys some special advantages in taking up plantation of tree-borne oil seeds for production of bio diesel due to vast unutilized land. The use of biodiesel results in substantial reduction of un-burnt carbon monoxide and particulate matters. It has almost no sulphur, no aromatics and more oxygen content, which helps it to burn fully. Its higher cetane number improves the combustion. Sunflower and rapeseed are the raw materials used in Europe whereas soyabean is used in USA. Thailand uses palm oil, Ireland uses frying oil and animal fats. In India vast research has been done on biodiesel from jatropha oil. It is proposed to use nonedible oil for making biodiesel, as consumption from edible oil is very high in India.

Firstly the required sample of linseed oil was taken in a conical flask and preheated to 600C. Then methanol (by volume) and KOH (by weight) was mixed and stirred in a separate conical flask. After that the stirred sample was added in the preheated linseed oil sample and again mixed properly by stirring. This mixture was then constantly stirred for different reaction time (30 min, 45min, and 60min) at a constant temperature of 600C inside a water bath shaker. After this the stirred sample was taken out and was poured in a separating funnel to separate the glycerol from the methyl ester. After 24 hours the glycerol was removed and separated to obtain the methyl ester. For the purification purpose methyl ester was washed and dried to remove the excess methanol, KOH, and other impurities.
