Paper Title
Experimental Study Of Performance Parameters And Engine Out Emissions Of Oxygenated Blends In A Direct Injection CI Engine
Abstract
Compression ignition (CI) engines are widely used in transportation sector due to its fuel efficiency and low cost
compared to its counterpart spark ignition (SI) engines. But the emissions produced from these engines create more
environmental pollution. The present research work aims to utilize Dibutyl Maleate (DBM) additives in a diesel engine to
study its performance and emissions for improving the environmental conditions. Dibutyl Maleate is mixed with diesel in the
proportions of 4% and 7% by volume for all the load ranges of the engine. All tests were conducted at steady state.
Performance parameters such as Brake Specific Energy Consumption (BSEC) and Brake Thermal Efficiency (BTE) were
studied. Exhaust emissions such as CO, unburnt HC, NOx and smoke were studied. Test results showed that 7% DBM by
volume is the best proportion for improving the performance and reduce the emissions of the CI engine.
