What is it about?

This paper investigates the environmental impact of using low-carbon fuels in a diesel engine, focusing on both regulated and unregulated emissions. The study explores how different fuel blends affect emissions of pollutants, such as formaldehyde and aldehydes, under various engine operating conditions. The findings reveal that while oxygenated fuels may reduce certain emissions at low loads, their impact varies at different engine loads. Optimizing the engine for low-carbon fuels can effectively reduce nitrogen oxide emissions but may lead to increased nitrous oxide emissions. Overall, the research sheds light on the potential of low-carbon fuels to meet environmental regulations without sacrificing overall emissions performance in diesel engines. This information is crucial for both researchers and the general public, offering insights into sustainable alternatives for a cleaner and greener transportation sector.
