Air pollution by diesel traffic became a concern in the UK 1950s. Exposure levels were assessed via probing light absorption of filter samples, which was translated to mass concentration “diesel smoke” (DS), based on results measurements exhaust test engine. We convert these DS values concentrations Elemental Carbon (EC), current proxy for exhaust. In recent study literature and an earlier own ...
Abstract To extract information on elemental components and PM characteristics from smoke number (SN) filter paper, we were performed analysis by micro-PIXE. As a result of the SN filter, composition jet engine exhaust was obtained. Regarding have been collected for each difference in thrust various aircraft engines at turbine test cells around world. By periodically analyzing such it is possib...
This paper aims to investigate the emission characteristics of biodiesel prepared from waste cooking oil. The characterization performance blended fuel in diesel engines results an improvement and a reduction hydrocarbon carbon monoxide emissions. Various amounts were mixed with leftover oil create final product. In order explore function, combustion range, properties engines, setup described h...
Increase in energy demand, stringent emission norms and depletion of oil resources led to the discovery alternative fuels forinternal combustion engines. Many like alcohols, petroleum gas, compressed natural gas have been alreadycommercialized transport sector. In present work, Pongomia Neem are blended with diesel used as analternate fuel for CI The can be converted into bio using a chemical p...
Polycyclic aromatic hydrocarbons (PAH) are common air pollutants generated from incomplete combustion. The inhalation of exhaust fumes in urban areas has been suggested to be an additional contributing factor. This study investigated the influence of urban traffic exposure, personal lifestyle factors and metabolic enzyme polymorphisms on the urinary 1-hydroxypyrene (1-OHP) level, approximating ...
Past studies revealed that Foeniculum vulgare oil biodiesel (FVB) can be used as a good candidate for diesel fuels. Ammonia (NH3) fuel additive mixed with other fuels to eliminate some disadvantages of the in engine performance and emission. In view such information, this study aims investigate effects FVB NH3 on emission parameters Diesel-RK Programme. study, was different proportions (FVB100,...
This study presents an experimental and analytical investigation on the effects of using methyl ester linseed oil (MELO)-diesel blend B10, B20, B30 with hydrogen injection 5%, 10%, 15% in a VCR (Variable Compression Ratio) diesel engine, operated compression ratios (CRs) 15, 16, 17, 18 DFM (duel fuel mode). also gives emphasis optimized emissions CO, CO2, NO, smoke, when engine was MELO-diesel ...
In order to investigate the effect of environmental wind on a tunnel with one blocked end fire under natural ventilation, series numerical simulations were conducted using large eddy simulation method in this study. The model is established by software FDS, and 36 groups working conditions such as speed 0-5m / s angle 45-135 are simulated. Combined results smoke spread, temperature velocity vec...
In South Korea, where mountainous terrain accounts for a significant proportion of the country, tunnels are essential reaching destinations via shortest possible route. Tunnels high-traffic areas with only two exits, making them vulnerable to large-scale disasters in event fire. However, existing longitudinal-flow-type exhaust systems (jet fans) insufficient effective smoke during tunnel Herein...
