Karanja and Rapeseed Biodiesel: An Experimental Investigation of Performance...Er Sandeep Duran
In this research work the detailed investigation on performance and combustion characteristics of four stroke single cylinder engine with karanja and rapeseed biodiesel and its blends with diesel (in proportions of 20% and 50% by volume) under various load i.e. at no load, 25%, 50% and full load was assessed. At full load KB50 (karanja biodiesel blend) has been recorded lowest rate of pressure rise. KB20 has lowest
recorded BSFC as compared to all others of biodiesel for all loading condition even than diesel. The RB20 (rapeseed biodiesel blend) recorded maximum BMEP at full load. KB20 was recorded with maximum brake thermal efficiency at full load. So on the basis of performance and combustion parameters KB20 appears to be best alternative fuel than other blends of karanja biodiesel and rapeseed
biodiesel even than diesel.
The document presents research on the production and testing of biodiesel from karanja oil. Key points:
- Karanja biodiesel was produced via base-catalyzed transesterification of karanja oil and tested in a diesel engine.
- Test fuels of B20, B50 and B100 blends showed improved emission profiles but lower efficiency compared to diesel.
- Smoke and NOx emissions increased with higher biodiesel content while CO and HC decreased at medium loads.
- Further studies on engine modifications, emissions reduction and biodiesel properties were recommended.
The document summarizes Prashant Bhushan's research internship at Indian Institute of Technology Guwahati under Dr. M. Ravi Sankar from May 24th to July 11th 2013. The research focused on machining with eco-friendly cutting fluids as an alternative to traditional petroleum-based fluids. Some alternatives studied included vegetable oils, bio-cutting fluids, liquid nitrogen, and ionized air cooling systems. The internship analyzed these fluids for their performance, costs, environmental impact, and health and safety properties to evaluate their viability as sustainable replacements for cutting fluids.

This document discusses biodiesel production from karanja oil. It introduces biodiesel as an alternative fuel made from vegetable oils and animal fats that can substitute for or be blended with diesel fuel. It then discusses different methodologies for biodiesel production, including direct use/blending of vegetable oils, microemulsions, pyrolysis, and transesterification. The document focuses on transesterification, the most common process, where triglycerides from oils react with alcohol in the presence of a catalyst to produce fatty acid alkyl esters (biodiesel) and glycerol. It notes various catalysts used, advantages of biodiesel, and non-edible oil resources in
This document presents information on Pongamia oil as an alternative fuel. It discusses how Pongamia oil is extracted from seeds of the Pongamia tree and has properties similar to diesel. Experimental testing of Pongamia oil blends in diesel engines showed satisfactory performance with minor issues. Using Pongamia oil could help address the problems of limited petroleum resources and reduce dependence on imports while providing economic benefits to local communities.
