Emission Control and Aldehyde Reduction Using Fish Oil Methyl Ester, Diethyl Ether, and Butanol Blends in CI Engines

Abstract

This study explores the analysis and mitigation of emission pollutants and aldehyde potential through the use of blends comprising Fish Oil Methyl Ester, Diethyl Ether, and Butanol in both conventional and Low Heat Rejection (LHR) Compression Ignition (CI) engines. The primary goal is to evaluate the effectiveness of these biofuel blends in reducing harmful emissions while maintaining engine performance. The experiments were conducted on a single-cylinder, four-stroke LHR diesel engine modified to operate with various fuel blends. Emission characteristics, including carbon monoxide (CO), Oxides of Nitrogen (), Smoke opacity and hydro carbon (HC) includes aldehydes were measured and compared to those of pure form of FOME and DEE and butanol blend fuel. Special emphasis was given to the examination and measurement of aldehyde emissions, given their substantial implications for human health and environmental quality. The results demonstrate that the use of FOME, DEE, and butanol blends significantly reduces CO, HC, and Smoke emissions.  emissions showed variable trends depending on the blend composition. Aldehyde emissions were notably lower in blends with higher concentrations Iso butanol and play a crucial role in controlling aldehyde formation. The study concludes that 50%FOME, 15%DEE, and 35% butanol blends are promising alternatives to conventional fuel with the percentage 52.4%, 8%, 14.11%, 11.8% reduction of CO, , and HC along with aldehydes offering substantial reductions in harmful emissions. It was also noticed that from the results of emissions such as CO, smoke opacity and Hydrocarbon with aldehydes for LHR Engine were reduced by 17.2%, 28.8%, 2.4% with mixture of DEE and butanol additives and FOME blend, but the  has increased with addition of DEE additive by 4.7%. According to the results, it is suggested to use FOME50DEE15BTN35 mixed fuel in CI engines reduce emissions.
