Emissions of selected gas pollutants in the application of the additive Envirox™

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, Envirox TM . It was found that the additive based on CeO 2 nanoparticles reduces emissions of hydrocarbons C x H y , and NO x , while emissions of CO 2 remain comparable or slightly lower and CO emissions even significantly increase. Dependence of tested emissions on reduced torque TM R , engine power P and revolutions f was observed as well.

Economic, technical and environmental aspects of fuel additive ENVIROX during trials with diesel engines

“…The additive enables to obtain more energy from fuel and to reduce its consumption, remove the rest of soot deposits in the engine combustion and while minimizing the creation of some contaminants [18,19]. Chemical processes are presented in equations in [24]. CeO 2 catalyst regeneration takes place according to the formulas in [24] and according to the final equation (1).…”

“…The calculation of emission of i-th pollutant is based on the knowledge of value of emission factor i m Ef [g kg -1 ], which is in compliance with the relation (2) in [24] given by mass of i-th pollutant relative to mass unit of consumed fuel. Where m i [g] is the mass of i -th pollutant, m F [kg] mass of consumed fuel, M i molar molecular mass of i-th pollutant [g mol -1 ], M F [kg mol -1 ]…”

“…Emission factors of i-th contaminant can be calculated in equation 3, which can be obtained by substitution of expression n d × (N F ) -1 . The calculation of emission factors is based on equation describing fuel combustion and material balance of carbon, hydrogen, oxygen and nitrogen Furthermore, the substance amount of dry gas entering The theoretical calculation for molar fraction of unmonitored elements as well as conversion of concentrated elements to the moist air is done in [24]. Amount of fuel consumed can be calculated from the volume speed of streaming damp combustion gas in the sampling extension.…”

“…Furthermore relations to calculate the concentration of water vapor and calculation of fuel composition were necessary. The calculation of emission factors was derived in equation for  F = M F × a -1 [24].…”
