This paper deals with the experimental study of combustion characteristic of diesel blended with n-pentane and diethyl ether (DEE). The ignition delay Characteristic of diesel combustion system fuelled with n-Pentane and DEE blends with pure diesel is investigated. The experiment conducted at various pressures and temperatures of air inside the combustion chamber. An experimental set up was designed based on an optical method for the measurement of ignition delay. The result reveals that ignition delay of diesel fuel spray decreases with increases in the temperature and pressure of hot air. Results also show that the effect of methyl group being more dominant at low ignition temperatures whereas the alkyl groups are more effective at higher temperature. The temperature and pressure of hot air inside the combustion chamber are the main factors for ignition delay. Ignition delay of 10% and 20%, n-pentane blends is higher than pure diesel at low temperature while at high temperatures it is nearly equal to the pure diesel. However 30% and 40% n-pentane blends increased the ignition delay. Ignition delay of 10%, 20%, 30% and 40% blends of DEE is lower than pure diesel. DEE reduces the ignition delay of diesel fuel effectively at lower temperatures.
