An experimental study of the ignition characteristic of solid cone fuel spray for a high speed diesel engine for diesel fuel at various injection pressure (100 bar, 200 bar and 300 bar) is carried out to get the effect of injection pressure on ignition delay and duration of burning. The ignition delay of diesel fuel spray was measured by recording the time delay between the event of ignition and the event of appearance of flame inside the combustion chamber by using digital storage oscilloscope. For this purpose an experimental set up was developed with the emphasis on optical method for detecting flame. The measurement of ignition delay was taken at various cylinder pressures (20, 30 and 40 bar) for different surface temperature (623K, 673K and 723K). Main objective of this project was to study the parameter of emission and their control. The result presented here shows that, ignition delay and duration of burning of diesel fuel decreases with increase with injection pressure and also with increases in hot surfaces temperature and also with increases in cylinder pressure.

Abstract


An experimental study of the ignition characteristic of solid cone fuel spray for a high speed diesel engine for diesel fuel at various injection pressure (100 bar, 200 bar and 300 bar) is carried out to get the effect of injection pressure on ignition delay and duration of burning. The ignition delay of diesel fuel spray was measured by recording the time delay between the event of ignition and the event of appearance of flame inside the combustion chamber by using digital storage oscilloscope. For this purpose an experimental set up was developed with the emphasis on optical method for detecting flame. The measurement of ignition delay was taken at various cylinder pressures (20, 30 and 40 bar) for different surface temperature (623K, 673K and 723K). Main objective of this project was to study the parameter of emission and their control. The result presented here shows that, ignition delay and duration of burning of diesel fuel decreases with increase with injection pressure and also with increases in hot surfaces temperature and also with increases in cylinder pressure.
