The power sector in Iran accounts for a share of 28.2 percent of the total CO2 emissions, so it is the biggest emitter of greenhouse gases. This study uses Logarithmic Mean Divisia Index (LMDI) technique to examine the role of five factors (economic growth, fuel intensity, electricity intensity, structure and quality of fuel) influencing CO2 emissions of the Power Plant sector in the period 1...
This article analyzes the influence of the ignition retardation on the fuel consumption, the cumulative tailpipe hydrocarbon emissions, and the temperature inside the three-way catalytic converter in a gasoline direct injection engine operated under idling conditions. A dedicated cylinder-individual, model-based, multivariable controller was used in experiments in order to isolate the effect of...
Using a portable emissions measurement system, 16 gasoline passenger cars were tested on a fixed route consisting of different types of roads in Macao and the data were normalized with the vehicle-specific power bin method. The normalized HC, CO and NOX emission levels of the seven passenger car samples with model year older than 2000 were 3.19 ± 5.04, 14.59 ± 22.88, 2.57 ± 2.12 g/km, respectiv...
Abstract In improving performance and reducing exhaust emissions in combustion engines, the addition of ozone to air supplied chamber was studied. this research, can be produced using plasma technology (plasma-ozone) which is a simple eco-friendly technology. Plasma-ozone generated Dielectric Barrier Discharge (DBD) method. Air passed plasma-ozone reactors at different voltages with an variatio...
Alternative fuels for internal combustion engines (ICE) emerge as a promising solution more sustainable operation. This work assesses and performance of the dual-fuel operation in spark ignition (SI) engine that simultaneously integrates acetone–butanol–ethanol (ABE) hydroxy (HHO) doping. The study evaluates four fuel blends combine ABE 5, 10, an HHO volumetric flow rate 0.4 LPM. standalone gas...
The Double dividend hypothesis briefly demonstrates that by replacing different kinds of distortionary taxes with environmental ones, not only the lesser pollutants would be emitted (the first merit), but the more productivity and public welfare would be gained (the second one). Given the urgent need of reducing emissions in Iran, levying taxes on carbon, aimed at reducing carbon dioxide by 12 ...
Air pollution is an example of a negative externality; it imposes harmful effects and costs on people other than polluterS. In controlling air pollution, efficiency argument implies that, there is a rolefor the government to play. Studies show that taxation of fuels can be a powerful indirect instrumentfor controlling air polluticn because of the association between fuels use and emissions. In ...
Cooking in the developing world generates pollutants that endanger the health of billions of people and contribute to climate change. This study quantified pollutants emitted when cooking with a three-stone fire (TSF) and the Berkeley-Darfur Stove (BDS), the latter of which encloses the fire to increase fuel efficiency. The stoves were operated at the Lawrence Berkeley National Laboratory testi...
population growth and increasing industrial and agricultural activities that cause ghg emissions and risk from environmental management is a serious challenge. in this research, the ghg emissions from peanut production as a potential feedstock for biodiesel fuel was investigated. data were collected through interviews with 75 peanut farmers. the cultivated areas were divided into three categori...
