porous media has interesting features in compared with free flame combustion due to the extended of the lean flammability limits and lower emissions. advanced new generation of internal combustion (ic) engines are expected to have far better emissions levels both gaseous and particulate matter, at the same time having far lower fuel consumption on a wide range of operating condition. these crit...

Microscopic urban traffic simulators embed the most detailed traveler behavior and network supply models. They represent individual vehicles and can therefore account for vehicle-specific technologies. These simulators can be coupled with instantaneous energy consumption and emissions models to yield detailed network-wide estimates of energy consumption and pollutant emissions. Nonetheless, the...

15. Supplementary Notes Project performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration. 16. Abstract When TxDOT began using an ultra-low sulfur diesel fuel, Texas Low Emission Diesel (TxLED), they commissioned a simultaneous study of the effectiveness of the use of TxLED by both the TxDOT fleet and their contractors, the Associated General Co...

The emissions of carbon dioxide and nitrogen and sulphur oxides for electricity generation with coal and biomass co-firing are investigated and the furnace gas temperature assessed. The study uses simulation and considers fuel combinations based on two coals (bituminous coal, lignite) and four types of biomass (rice husk, sawdust, chicken litter, refused derived fuel). With increasing biomass, ...

This paper proposes a method for estimating emissions of carbon dioxide (CO2) and particulate matter (PM) from ships using Automatic Identification System (AIS) data. The method can be summarized in three steps : 1) capture of AIS data, 2) estimation of ships resistance, propulsion power, engine power and fuel consumption, 3) estimation of CO2 and PM emissions based on fuel consumption. The met...

Global air pollution is a serious threat caused by excessive use of fossil fuels for transportation. Despite the fact that diesel fuel is a big environmental pollutant as it contains different hydrocarbons, sulphur and crude oil residues, it is yet regarded as a highly critical fuel due to its wide applications. Nowadays, biodiesel as a renewable additive is blended with diesel fuel to achie...

in this study the performance and emissions characteristics of a heavy-duty, direct injection, compression ignition (ci) engine which is specialized in agriculture, have been investigated experimentally. for this aim, the influence of injection timing, load, engine speed on power, brake specific fuel consumption (bsfc), peak pressure (pp), nitrogen oxides (nox), carbon dioxide (co2), carbon mon...

the goal of this study was to analysis the greenhouse gas (ghg) emissions of pasta production. data for this study was collected from durum wheat farms of three provinces of iran. data of soil properties, transportation and pasta factory stages were collected and analyzed, using simapro software, ecoinvent data base and global warming potential (gwp) 100 years method. epic model was used to cal...

35 This paper describes research undertaken to establish plausible fuel-speed curves (FSC) for 36 hypothetical advanced powertrain vehicles. These FSC are needed to account for the effects of 37 congestion in long-term transportation scenario analysis considering fuel consumption and 38 emissions. We use the PERE fuel consumption model with real-world driving schedules and a 39 range of vehicle...

Nowadays, the increase of fossil fuel consumption intensifies the crucial role of architects. As buildings consume over one-third of the used energy, the society of architects is held responsible for this consumption. Therefore, the amount of energy used by a building is directly related to its design; meaning that reduction of energy consumption should be targeted at the design stage. In this ...
