Abstract
Currently, internal combustion engines power more than 99.9% of vehicles in circulation. When compared to SI engines, CI engines are more efficient, have better fuel economy, and lower CO2 emissions. In contrast, they emit a greater quantity of nitrogen oxide (NOx) and particulate matter (PM). One of the options to reduce emissions from CI engines is the addition of hydrogen (H2) during the combustion process This study evaluated the effects of the application of gases obtained from the ethanol reforming on the performance and emissions of a diesel engine. Different proportions of ethanol/steam and reforming temperatures generated different percentages of H2 and inert gases. For larger quantities of hydrogen added to the combustion chamber, there was an increase in the pressure and internal temperature of the cylinder. Regarding specific consumption, the addition of these gases caused an improvement of 17.22%. In terms of emissions, there was a decrease in the amount of NOx. The addition of reformed gases increased the emissions of CO, particulate matter, and unburned hydrocarbons.
