FTIR spectroscopy of methyl butanoate-air and propane-air low pressure flat flames
The combustion of fatty acid methyl esters (FAME) in diesel engines has been shown to produce lower emissions of carbon monoxide (CO), unburned hydrocarbons, greenhouse carbon dioxide (CO2), and particulate matter than petroleum based fuels. However, most diesel engine studies have shown that emission of oxides of nitrogen (NOx) typically increase for methyl ester fuels in comparison to petroleum based fuels. Many theories have been proposed to explain these NOx increases from FAME combustion but a general consensus has emerged toward two primary mechanisms: (1) the increased bulk modulus of ...
