“A Study on Experimental Investigation on Performance, Emission Analysis and Tribological Behaviour of a Single Cylinder Diesel Engine fuelled with Different Vegetable Oils - A Review”

Abstract

Conventional fuels are depleting very fast and prices of these fuels are also increasing rapidly; therefore, there is a direct need of alternative fuels which can resolve the twin crisis of energy and environment. Vegetable oils are renewable and biodegradable, which can be used as an alternative of conventional fuels. Lot of research has already been completed on bio-diesel as well as on straight vegetable oil as fuel of Internal Combustion engines. In this review paper Performance and emission characteristics of a diesel engine operated with straight vegetable oils has been compared and discussed. Depletion of fossil fuel resources and continuous release of greenhouse gases to the environment forces the researchers to develop alternative fuel technologies that are environmentally more acceptable. Trans-esterified vegetable oil derivatives also NQRZQDVĴELRGLHVHOµDSSHDUWREHWKHPRVWFRQYHQLHQWPHWKRGRI utilizing bio- origin vegetable oils as replacement fuels in compression ignition engines. In the present study, biodiesel was prepared from different non edible oil through tans-esterification process and the property of biodiesel was compared with base standard diesel fuel. In other studies experiments were carried out to study performance and emission characteristics of a diesel engine fuelled with diesel fuel, a sunflower oil and its blends 10 % by volume, (BD-10), 2or 0 % by volume ( BD-20), 30 % by volume ( BD-30), 40 % by volume ( BD-40), 50 % by volume ( BD-50), 100 % by volume ( BD-100). In these tests have been conducted on four stroke, single cylinder, water cooled vertical, water cooled high speed diesel engine with different loads at constant speed of 1500 rpm. The results were represented in the form of BSFC, Mechanical efficiency, BTE, and emission characteristics of CO, CO2, HC and NOX . From the study it is found that BD-10, BD-20, BD-100 Biodiesel blends given better Mechanical efficiency. The purpose of the work was to enhance the performance and emission characteristics and to examine the possibility of use of Tire-Derived Pyrolysis Oil in the compression Ignition Engine
