  • Engine performance and Pollutant Emission of an SI engine using ethanol–gasoline blended fuels
    Atmospheric Environment, 2002
    Co-Authors: Wei Dong Hsieh, Rong Hong Chen, Ta Hui Lin
    Abstract:

    The purpose of this study is to experimentally investigate the engine performance and Pollutant Emission of a commercial SI engine using ethanol–gasoline blended fuels with various blended rates (0%, 5%, 10%, 20%, 30%). Fuel properties of ethanol–gasoline blended fuels were first examined by the standard ASTM methods. Results showed that with increasing the ethanol content, the heating value of the blended fuels is decreased, while the octane number of the blended fuels increases. It was also found that with increasing the ethanol content, the Reid vapor pressure of the blended fuels initially increases to a maximum at 10% ethanol addition, and then decreases. Results of the engine test indicated that using ethanol–gasoline blended fuels, torque output and fuel consumption of the engine slightly increase; CO and HC Emissions decrease dramatically as a result of the leaning effect caused by the ethanol addition; and CO2 Emission increases because of the improved combustion. Finally, it was noted that NOx Emission depends on the engine operating condition rather than the ethanol content. r 2002 Elsevier Science Ltd. All rights reserved.

  • Study of water Pollutant Emission trading theory based on water quality models
    Environmental Pollution & Control, 2015
    Co-Authors: Sun Shaoche
    Abstract:

    With the background that China's Emission trading system was expected to be fully improved,the construction of water Pollutant Emission trading system was particularly weak.Combining with the development and problems of water Pollutant Emission trading system in China,a calculation method of water Pollutant Emission trading was presented in the paper,which based on the water quality models in order to meet"Integrated wastewater discharge standard"(GB 7978-2002)and"Environmental quality standards for surface water"(GB 3838-2002)as the prerequisite.The method could be used to quantify the feasibility of Emission trading and predict the changes of water quality caused by the trading.

  • thermal modeling of a trigeneration system based on beta type stirling engine for reductions of fuel consumption and Pollutant Emission
    Journal of Cleaner Production, 2018
    Co-Authors: Mahmood Chahartaghi, Mohammad Sheykhi
    Abstract:

    Abstract Energy recovery is one of the most important ways to clean production and reduce of carbon dioxide Emission. Therefore, in this paper, a trigeneration system (combined cooling, heating and power or CCHP) is suggested to reduce fuel consumption and Pollutant Emission for building applications. The system consists of two beta-type Stirling engines as prime movers, a heat recovery system, an absorption chiller, and a power generator. The Stirling engine has been modeled based on a non-ideal adiabatic analysis in which the frictional and thermal losses of the engine have been considered using a developed numerical code. For model validation, the specifications of the GPU-3 Stirling engine have been used and the results have been compared with the experimental data and previous models. Moreover, the energy modeling of the absorption chiller has been performed using Stirling engine waste heat. Then, the effects of engine rotational speed, wall temperature of heater, and regenerator length on efficiency, fuel consumption, and carbon dioxide Emissions reduction have been studied and the appropriate values have been presented. The results show that in these conditions, the appropriate values for the electrical efficiency and trigeneration efficiency are 27.31% and 74%, respectively. Furthermore, the fuel consumption and carbon dioxide Emission of this system have been encountered with reduction of 31.83% and 38.44% in comparison with conventional energy systems for buildings of the same conditions.

  • Estimating air Pollutant Emission factors from open burning of rice straw by the residual mass method
    Atmospheric Environment, 2012
    Co-Authors: Tai-yi Yu, Len-fu W. Chang
    Abstract:

    Abstract Air Pollutant Emission factors produced by open burning of rice straw were estimated using the residual mass method which incorporated ambient air-quality and meteorological data of measured stations. The residual mass method regarded the residual mass of air Pollutants as Emissions caused by the open burning of rice straw. Lasting from November 27–28, 2002, the selected episode resulted in the most serious air pollution in the recent decade in terms of open burning of rice straw, significantly degrading air quality in central-south Taiwan. Emission factors from open burning of rice straw, as modeled by the residual mass method, were 30.3 ± 1.45, 5.14 ± 0.13, 3.44 ± 0.09, 6.28 ± 0.34, and 0.058 ± 0.003 g kg−1 for CO, NMHCs, NOx, PM10 and SO2, respectively. The maximum daily Emissions of CO and PM10 were 1000 kg km−2 and located at central-south Taiwan. Additionally, Emissions of CO and PM10 in EPS were 7.67 and 9.33 times higher than MON during the rice straw burning episode. The spatial Emission of EPS and MON were also presented with the residual mass method. Comparing our results with those of other studies revealed that calculated Emission factors in this study were in an acceptable range.
