Research results show that mixing ethanol with gasoline at a certain ratio helps to improve fuel consumption and engine emissions. Gasoline mixed with 5% ethanol (E5) has an average reduction in fuel consumption and CO, HC, NOx emissions of 8.4%, 9.4%, 4% and 5%, respectively, compared to RON95 gasoline. Adding nitroparaffins to alcohol-based gasoline helps to further improve fuel consumption and engine emissions
E5 gasoline mixed with 0.1% additives has an average reduction in fuel consumption and CO, HC, NOx emissions of 11.1%, 3.2%, 4.3% and 3.4%, respectively. Compared with RON95 gasoline, the additive E5 gasoline has an average reduction in fuel consumption and CO, HC, and NOx emissions of 19.5%, 12.6%, 8.3% and 8.5%, respectively.
