Determination of the Impacts of Nanoparticule Additives into diesel fuel on NO_x Emmision Characteristics of a Heavy Duty Diesel Engine

摘要

Transport is crucial for economic and social development of a society as it serves a key role for transportation of goods and people. But it is not free of negative externalities. Operation of transport vehicles require energy use and this energy is mostly generated with fossil fuel combustion. Unfortunately, the fossil fuel combustion comes with both global emissions (CO_2, N_2O, CH_4), which cause climate change, and local emissions (PM, NO_x, HC, CO, O_3), which cause adverse health effects and damage natural environment. In this paper the level of NO_x emission by adding fuel additive metal oxide based nanoparticles in heavy duty engines were investigated. Three different nanoparticle additives namely Titanium Oxide (TiO_2), Silicon Oxide (SiO_2) and Zinc Oxide (ZnO), were added to diesel fuel at the dosages of 15, 20 and 25 ppm. Eventually, the most proper additive and addition dosages were indicated.
