The potential of di-methyl ether (DME) as an alternative fuel for compression-ignition engines: A review

Soot processes in compression ignition engines

A detailed chemical kinetic modeling approach is used to examine the phenomenon of suppression of sooting in diesel engines by the addition of oxygenated hydrocarbon species to the fuel. This suppression, which has been observed experimentally for a few years, is explained kinetically as a reduction in concentrations of soot precursors present in the hot products of a fuel-rich diesel ignition zone when oxygenates are included. The kinetic model is also used to show how different oxygenates, ester structures in particular, can have different soot-suppression efficiencies due to differences in the molecular structure of the oxygenated species.

Chemical kinetic modeling study of the effects of oxygenated hydrocarbons on soot emissions from diesel engines.

This paper proposes a structure for the diesel combustion process based on a combination of previously published and new results Processes are analyzed with proven chemical kinetic models and validated with data from production-like direct injection diesel engines The analysis provides new insight into the ignition and particulate formation processes, which combined with laser diagnostics, delineates the two-stage nature of combustion in diesel engines Data are presented to quantify events occurring during the ignition and initial combustion processes that form soot precursors A framework is also proposed for understanding the heat release and emission formation processes

The effect of oxygenated agent addition to diesel fuel on diesel combustion and emissions was investigated. Oxygenated agent addition to diesel fuel resulted in a slight change in NOx a decrease in CO and THC, and a significant reduction in smoke and TPM specially in the higher load range. The reduction in smoke and TPM was explained reasonably by an increase in oxygen content in fuels which was almost independent of the type of oxygenated agent used. Oxygenated agent addition resulted in a slight increase in BSFC [g/(kW·h)], but did not result in a change in BSEC [MJ/(kW·h)]. Thus the thermal efficiency remained unchanged on addition of oxygenated agents into diesel fuel.
