정적연소기에서 라디칼 유도분사를 이용한 희박혼합기의 연소특성에 관한 연구(2)

다국어 초록 (Multilingual Abstract)

A prior fundamental study was executed using a constant volume chamber to improve the buming properties oflean pre-mixture by the injection of active radicals generated in the sub-chamber. In consequence, RI method shows remarkable progress in the aspects of buming velocity and combustible lean limit compared with SI method. In this study, the necessary additional works have been performed to be based on the former results. We changed parameters as the initial temperature and the initial pressure of mixture. And the effects of residual gas at issue in a real engine were investigated. As a result, the effects of initial temperature were significant, but on the other hand, those of initial pressure were slight. The correlation of passage hole number between overall passage hole area was grasped. And the more detailed analysis is required on residual gas.
