ABSTRACT

 

Diesel engines dominate in the heavy-duty applications due to their reliability and higher efficiency. However, diesel engines emit significantly higher amount of harmful pollutants such as oxides of nitrogen (NOx) and particulate matter (PM). It has been established that diesel PM has a significant contribution to air pollution. The present study shows that such harmful pollutants from diesel engine can be reduced significantly using dual dueling. Natural gas (NG) and simulated biogas are used in this study. Along with the gaseous emissions such as NOx and unburned hydrocarbons, PM is measured using the traditional gravimetric method and also characterized by the thermogravimetric analysis (TGA). Results are compared between diesel and dual fueling while the engine operating conditions are kept the same.
