Abstract

The value of selected emission factors was monitored in the operation of an older type of engine testing bench using diesel and compared with the same parameters monitored under similar conditions with the addition of the additive, EnviroxTM. It was found that the additive based on CeO2 nanoparticles reduces emissions of hydrocarbons CxHy, and NOx, while emissions of CO2 remain comparable or slightly lower and CO emissions even significantly increase. Dependence of tested emissions on reduced torque TMR, engine power P and revolutions f was observed as well. Keywords: additive, emission factor, nano-particle, environment, cerium dioxide, carbon mono-oxide, nitrogen oxide. 1 Introduction Escalating activities of human society in order to ensure a higher standard of living brings along a number of negative externalities. Among the important, and by the lay and professional community strongly discussed externalities, belongs the increase of burden to the atmosphere through the implementation of industrial and agricultural activities, energy production, waste management and household management. To the increase in ambient air pollution also contributes a significant level of mobile assets, consisting primarily of passenger and goods transport [1]. It is estimated that transport contributes to overall air pollution by carbon monoxide (CO) and carbon dioxide (CO2) emissions by 37%, a mixture of nitrogen oxide and nitrogen dioxide (NOx) by 30%, and volatile organic compounds (VOCs), about 24%. Besides the above, the quantitative aspect of the
