Analysis of performance Combustion and emission characteristics of Biodiesel water emulsions in low heat rejection di Diesel engine

Abstract

In this research, the heat is retained in the combustion chamber to improve the newlineefficiency and reduce emissions. This has been derived by coating ceramic to newlinethe valve facing the upper part of the piston and the lower part of the engine. newlineMaterial used for the ceramic coating is Partially Stabilized Zirconia (PSZ). It newlineis evident from the previous researches, that nearly all biodiesels emitted newlinemore NOX and smoke when fed into the conventional diesel engine. In this newlineresearch, such emissions have been regulated by using diesel-water and newlinebiodiesel-water emulsions as fuels for the coated engine. All the analyses newlinehave been carried out without altering the parameters of the engine structure newlinesuch as the time of passing the fuel to the engine, the force at which the fuel is newlinepassed to the engine and percentage of compacting the fuel. newlineFor this empirical study, the internal combustion engine uses atmospheric newlinepressure instead of forced induction method. As Kirloskar brand has a newlinenaturally aspirated engine, the same has been used. Several other parameters newlinelike, maximum pressure developed, maximum heat released have been newlinemeasured and the emission characteristics have been measured by a gas newlineanalyzer. To measure smoke opacity emission in HSU, smoke meter has been newlineused. The temperature of the system has been calculated using thermocouples. newlineA window based application to gather the data from the engine has been used newlinefor tracing out pressure angle graph and heat release curve. While the crank newlineangle decoder, pressure pick up sensor and signal conditioner gave feedback newlinesignal to the data acquisition system.
