Popis: There is an ever-increasing necessity for sustainable energy resources. The restrictions on diesel engines, which were already strict in the previous decade, are only going to increase in the next one. A zero-emission diesel engine has become an absolute necessity. Furthermore, it is critical to increase the thermal efficiency of these engines. Dimethyl Carbonate (DMC) is gaining popularity as an oxygenated additive to diesel due to its desirable boiling point and good solubility. The current work investigates the performance, emission and exergy parameters of a diesel engine with DMC as an additive. Additionally, we also explore the effects of oxygenation at the air side by introducing a turbocharger at the intake manifold. Four different blends of oxygenated additives were analysed with the turbocharger in operation. Here, a 5% blend of DMC produced the most desirable results. When a 5% blend of DMC with diesel was tried out, the brake thermal efficiency increased by 4 percent. At maximum brake mean pressure 4.8 bar, the maximum exergy efficiency was 65%. This blend also has least the brake specific fuel consumption and carbon monoxide emissions. These results emphasize the usage of DMC as an additive, and are of direct relevance to the alternative fuel industry—aiding it in making informed decisions about blending fuel additives.
