Theoretical analysis the use of dimethyl ether and diethyl ether in a diesel engine
(Sila Science, 2011)
In this study, the use of dimethyl ether (DME) and diethyl ether (DEE) in diesel engines as alternative fuels investigated. A commercial suction (naturally-aspirated) direct injection (SDI) automobile diesel engine was ...
Alternative gaseous fuels in port fuel injection spark ignition engines
(Elsevier Sci Ltd, 2011)
This paper investigates the use of alternative gaseous fuels in port fuel injection spark ignition engines via the Lotus engine simulation program. To this end, the engine model for a port fuel injection spark ignition ...
Abrasion Resistance of Cement Mortar with Different Pozzolanic Compositions and Matrices
(Asce-Amer Soc Civil Engineers, 2011)
Abrasion of concrete occurs due to scraping, rubbing, skidding, or sliding of objects on its surface. The abrasion resistance of concrete is influenced by a number of factors, such as compressive strength, surfacing finish, ...
Mineralogy and whole rock geochemistry of late Cretaceous sandstones from the eastern Pontides (NE Turkey)
(E Schweizerbartsche Verlags, 2011)
This study focuses on Upper Cretaceous sandstones of the Eastern Pontides to identify the source area, subaerial weathering level, and tectonic environment. Thirty four sandstone samples from six stratigraphic sections ...
ESTIMATION OF THE CARBON TO NITROGEN (C:N) RATIO IN COMPOSTABLE SOLID WASTE USING ARTIFICIAL NEURAL NETWORKS
(Parlar Scientific Publications (P S P), 2011)
Organic waste constitutes a majority of all municipal solid waste (MSW), a fact which yields some unfavorable results at open dumps, sanitary landfills, and incineration plants. As part of an integrated solid waste management ...
Thermodynamic, performance and emission investigation of a diesel engine running on dimethyl ether and diethyl ether
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2011)
This study investigates the use of dimethyl ether and diethyl ether in diesel engines as alternative fuels. A direct injection diesel engine was simulated via a thermodynamic cycle model for investigation. Thermodynamic ...
