小型定容燃焼容器を用いた多噴口ノズルの燃焼特性に関する研究

Effects of ambient temperature and density on combustion of diesel spray under high temperature and high pressure ambient were experimentally examined using a constant volume chamber of 60cc that simulates the combustion chamber of automobile diesel engine. It is confirmed that the ambient temperature and pressure has large effect on the shape of heat release rate, the ignition delay and the combustion duration. As the increase of ambient density and as the increase of ambient temperature, the ignition delay becomes shorter. In comparing with the results of 800cc combustion vessel, ignition delay shows the difference in the low ambient temperature range.
