The present work carries out an experimental comparative analysis of the performance and emission exhaust gases Otto cycle with four automotive times. comparison was made between alternative fuels such as E10, E15, E20, both 90 95 octane each commercialized fuel. tests were carried engine load corresponding to 25% maximum load. After carrying tests, following conclusions can be reached: on effe...

The impact of ship emission reductions can be maximised by considering climate, health and environmental effects simultaneously using solutions fitting into existing marine engines infrastructure. Several options available enable selecting optimum for different ships, routes regions. Carbon-neutral fuels, including low-carbon carbon-negative from biogenic or non-biogenic origin (biomass, waste,...

Stringent regulations governing automobile exhaust emissions are due to come into force i n the United States. Johnson Matthey have undertaken the development of platinum-based catalytic reactors for control of these exhaust emissions. Two new types of catalyst have demonstrated the feasibility of exhaust control by catalytic means, nnd have been incorporated on test vehicles to achieve emissio...

Airborne particulate matter, suspected to induce adverse effects on human health, have been one of the most important concerns regarding recent air pollution issues in Japan. To characterize regional and seasonal variations in emission sources of fine airborne particulate matter (d < 2 microm), monthly samples (n = 36 for each site) were collected at urban (Tokyo), suburban (Maebashi), and moun...

Unlike exhaust emissions, non-exhaust traffic emissions are completely unregulated and in addition, there are large uncertainties in the non-exhaust emission factors required to estimate the emissions of these aerosols. This study provides the first published results of direct measurements of size resolved emission factors for particles in the size range 0.25–2.5 μm using a new approach to deri...

One of the main factors contributing to greenhouse gas emissions in the environment is the production of pollutant gases in landfills. Collecting the landfill gases (LFG) effectively reduces the emission of gasses from the landfill site. A precise collection system for LFG can create the potential for energy generation in addition to emissions reduction. However, in Iran, the implementation of ...
