Abstract

The main objective of this study is to improve the performance and cleaning up of diesel engine's exhaust by fumigating known quantity of methanol and methyl ethyl ketone individually using a custom made Electronic fuel injector controlled by a microprocessor. To control the emission from diesel engine and to improve performance, alternate fuel and in-cylinder control techniques are used. The experimental study has been carried out in a single cylinder diesel engine. The experimental set-up is such that known quantity of methyl ethyl ketone is fumigated in the intake manifold using a microprocessor controlled electronic fuel injector. Results of the experimental study of a DI Diesel engine are presented, which show the influence of partial premixing fumigation of the intake air with methanol and methyl ethyl ketone fuel on the exhaust emissions and the engine performance parameters The result shows an appreciable reduction of emissions, such as, oxides of nitrogen, smoke density and marginal increase in the performance in fumigation mode for both the fuels and are compared with those of normal diesel engine.
