Certain investigations on the effect of Compression ratio over the performance And emission characteristics of CI engine with biodiesel blends

Abstract

The day by day increase in the usage of vehicle and the rising newlineenergy needs for the widespread industrial sectors in developing countries of newlinethe universe have led to a steady and steep increment demand of petroleum newlineproducts A thorough insight into the literature reveals that straight vegetable newlineoils used in engine leads to various problems like fuel filter clogging poor newlineatomization and incomplete combustion due to high viscosity high density newlineand poor non volatility At this juncture it becomes vital to channelize the newlineaim of this current research I e to find out a novel and renewable alternate newlinefuel for the compression ignition engines newlineThe objective of this study is to investigate the effect of newlinecompression ratio on combustion and to check the performance and emission newlinecharacteristics of diesel engine for certain alternate fuels like methyl esterbased newlinefuels edible waste cooking oils and one preheated with dieselblended newlinefuel The artificial neural network models have been developed to newlineobtain more accurate prediction of the responses of the performance newlinecharacteristics of methyl ester oils newlineIn line with the framed objective the effect of compression ratio on newlineCombustion performance and emission characteristics of alternate fuels is newlineobserved by engaging a direct injection DI single cylinder four stroke newlinevariable compression ratio multi fuel engine newline newline
