Abstract
An experimental investigation was conducted on a direct injection diesel engine using conventional and oxygenated diesel fuels. The main scope is to examine the effect of fuel oxygen enhancement for fuels with various aromatic content on engine performance characteristics and, mainly, on pollutant emissions. A mixture of diethylene glycol dimethyl ether (diglyme) and diethylene glycol dibutyl ether (butyl-diglyme) of approximately 20% by mass were added to a high-paraffinics and two commercial diesel fuels of varying aromatic fractions. An experimental apparatus was installed and engine tests were carried out on a naturally aspirated DI diesel engine at various operating conditions. The measurements were comprised of cylinder pressure diagrams, fuel consumption, exhaust smokiness, and exhaust gas emissions (nitrogen oxides, unburned hydrocarbons, and carbon monoxides). According to the experimental findings, the addition of oxygenated agents results in earlier initiation of combustion and in an increase o...
