Abstract
The rapidly increasing global population, combined with a corresponding increase in power plants, factories and automobiles, has led to a significant decline in air quality. This issue first came to the forefront in the Los Angeles basin during the late 1940s, primarily due to the region's high population density and unique meteorological conditions. The combination of industrial and vehicular emissions with the prevalent fog resulted in the formation of smog. In response to this growing concern, California began implementing emission standards in the 1960s. Researchers have explored various methods to mitigate emissions from internal combustion engines. One such approach involves the utilisation of oxygen-containing additives to enhance gasoline performance and reduce harmful emissions. This study aims to determine the potential of Dimethyl Carbonate (DMC) as an additive in reducing emissions. To achieve this objective, an experimental setup was established using a multi-cylinder, four-stroke spark ignition engine to test fuel blends containing DMC. Major Findings: The findings of this investigation revealed that gasoline blended with DMC exhibits lower levels of Carbon Monoxide (CO) and Hydrocarbon (HC) emissions compared to standard unleaded gasoline. However, the impact of DMC on Nitrogen Oxide (NOx) emissions appears to be negligible.
