Chhibber, Harish Chandra Joshi, Sanket Kumar Saxena Dept. of Chemistry Shivalik College of Engg., Dehradun., 248001 ABSTRACT: Sal seed oil is not only a green boon for the forest dwellers of Central Indian States of Orissa, Chattisgarh, and Madhya Pradesh but also it provides a sustainable medium for their livelihood by managing their several means of earning resources starting from arranging the different parts of this tree such as leaves, seeds andresins to use them as a substitute for confectionery item Cocoa butter, known as Cocoa Butter Equivalent (C.B.E.), a ingriedient of Chocolate, price, quantity and quality can be attributable and directly linked to its production. Apart from being a confectionery item, the sal seed oil now a days can also be used one of the better option for production of the vegetable oil based diesel or Biodiesel and its blend in a diesel engine such as direct injection engines. Biodiesel are vegetable oil methyl esters and can be used as a biodegradable transportation fuel in neat form or in blends with petroleum derived diesel in diesel engines. Biodiesel is similar to the conventional petroleum diesel. Biodiesel can be blended in any ratio for reduced emissions and the increased lubricity for better running vehicle. “MOST COMMON BLEND IS A MIX OF 20% BIODIESEL AND 80% PETROLEUM DIESEL, CALLED “B20” KEYWORDS: Sal Seed Oil as such or in Blend form 1. INTRODUCTION Vegetable oils are of two types (1) Edible (2) Nonedible, the examples of edible oil are soybeen, cashewnut, mustard, ground nut, unflower while examples of nonedible oil are ricebran, karanja, jatropha, linseed and castor. Vegetable oil based fuel can be most suited,appropriate and desired one in comparison to the mineral oil based diesel fuel if it will be containing of the following characteristics. (1).Long chain hydrocarbon structure. (2).Good ignition characteristics. (3).Increased lubricity in blended form. Diesel engines plays an important role and therefore have a big stake in carrying heavy load and thus becomes a important factor for claiming country’s good economy as freight and runs one’s country’s machinery at a very fast pace and in a controllable manner. Also diesel engine plays a vital role and its dominating attitude in the field of commercial transportation and agricultural methods on account of its superior fuel efficiency.Thus fuel efficiency is a characteristic of a diesel engine based on which certain predictions can be made as, (1).Diesel engine average (2).Distance covered/volume (3).Efficiency of its parts (4).Durability of essential parts. Because of shortage of fossil fuel resources we can not neglect the option of biodegradable and ecofriendly alternative such as vegetable oil based or biobased resources.If we want to overcome the scarcity of these green fuels then the better option is to go for BIOBASED FUELS. In other words it can be proved a better option for one’s nation economy and providing employment. It can be proved beneficial for maintaining O2 cover and climate. It has also been proved that vegetable oils from crops such as soybean peanut, sunflower, rapeseed, coconut, karanja, neem, cotton, mustard, jatropha, linseed and castor that was produced and cultivated in many parts of world and that lack fossil fuel reserves can boost up that nation’s energy related problems. Short term test flights gave positive results while long term endurance test gave comparable and approximately equivalent results.A slight difference was seen in thermal and ignition properties in cold weather in comparison to mineral fuel such as diesel. 2. DISCUSSION Sal seed oil or vegetable oil can be proved as an important fuel in place of fossil fuel or use of it as a blend encourages its production through the barren land and provides the necessity to use it as a viable or suitable alternate. We know that the concept of using vegetable oil as fuel for diesel engines is nothing new. Dr. Rudolph diesel first developed the diesel engine in 1895 with the
