A study of combustion characteristics for spray combustion by multi injection in a closed vessel

Internal combustion engines are the major source of air pollution. Especially, compression ignition engines in today's industrial and automotive general engines contribute the most to particulate emission and soot, and it is recognized that these emissions have a detrimental effect on human and earth environment. So, an improvement of spray combustion for diesel engines is of urgent necessity.

Experiments have been conducted to obtain essential data on spray combustion are influenced by impinging injection in a closed vessel. The effect of the impinging injection on maximum burning pressure, total burning time and mean flame speed is investigated at condition of 300K of initial temperature and 0.1MPa of initial pressure.
