In this paper, the concentration of soot during controlled combustion is analyzed using two fuels: acetylene (AC) and natural gas (NG). The stability was evaluated within the spatio-temporal standards generated by the system evolution, which was based on the measuring technique known as the...

Alcohol blends with hydrocarbon fuels for spark-ignition engine increase fuel octane rating and power for a given engine displacement and compression ratio. In this work, the influence of butanol addition to gasoline was investigated. The experiments were performed in a ported fuel injection...

Availability analysis is applied to cylinder of a spark ignition engine during the combustion process under surrogate fuels (iso-octane, n-heptane, toluene, and methyl-cyclohexane) for gasoline using a two-zone combustion model. Special attention is given to identification and quantification of...

The thermodynamic inefficiencies associated with any energy conversion process are expressed by the exergy destruction and the exergy losses associated with the process. Combustion processes exhibit very high thermodynamic inefficiencies caused by chemical reaction, heat transfer, friction, and...

With the advanced methods of digital image processing and optical sensing, it is possible to have continuous imaging carried out on-line in combustion processes. In this paper, a method that extracts characteristics from the flame images is presented to immediately predict the outlet content of...
