The challenging task in our ecosystem is to reduce acidic gas emissions some extent. Many gases are emitted from the industries like H2S, CO, CO2, SO2, NO, and NO2 as exhaust gases. Among these gases, NO2, SO2 acidic, which results adverse effects on humans, animals, plants. increase emission of CO2 both anthropogenic industrial sources resulted mitigation studies. absorption studies were carri...

Pollutant concentrations in the exhaust plumes of individual diesel trucks were measured at high time resolution in a highway tunnel in Oakland, CA, during July 2010. Emission factors for individual trucks were calculated using a carbon balance method, in which pollutants measured in each exhaust plume were normalized to measured concentrations of carbon dioxide. Pollutants considered here incl...

A general proecological urban road traffic control idea for the street canyon is proposed with emphasis placed on development of advanced continuum field gasdynamical (hydrodynamical) control model of the street canyon. The continuum field model of optimal control of street canyon is studied. The mathematical physics approach (Eulerian approach) to vehicular movement, to pollutants’ emission an...

TiO2 nanoparticle-encapsulating poly(vinyl chloride) (TEPVC) was combusted in a well-controlled laboratoryscale incinerator at a temperature of 700 °C, and then dioxins (PCDDs, PCDFs and coplanar-PCBs) formed in the exhaust gases were analyzed by high resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS). TEPVC sample was prepared by the suspension polymerization of vinyl ...

Due to stricter emission legislation, there is a need for more efficient control of diesel engines with exhaust gas recirculation(EGR). In particular, it is important to estimate the air/fuel ratio accurately in transients. Therefore a new engine gas flow model has been developed. This model divides the gas into one part for oxygen and one part for inert gases. Based on this model an observer h...

The presence of metals and metalloids in petrochemical products can infl uence the performance of engines, and contribute to shortening the lifetime of the machinery. In addition, some elements act as catalyst poison, contributing to increases in the amount of toxic gases and particulate matter emitted by vehicles. Silicon compounds such as siloxanes, for example, are added to diesel as anti-fo...
