The Effect of Combustion Promotion in Constant Volume Combustion Chamber with Sub-chamber

부실붙이 정적연소실의 연소촉진 효과

The effect of combustion promotion in a constant volume combustion chamber with sub- chamber located in the vicinity of spark plug, was analyzed for variables such as sub- chamber volume and diameter of orifice, and was also compared and evaluated with that of the chamber with sub-chamber which spark plug was located in the sub-chamber. Consequently, it was shown that decrease of duration of combustion in the latter case was larger than in the former case, but comparing by rate of overall combustion promotion that duration of combustion and pressure were both considered, the optimum configuration factor and the effect of combustion promotion were almost same in both cases.

본 연구에서는 주연소실쪽의 오리피스 근방에서 점화를 하는 부실붙이 연소실 에서 부실의 크기, 오리피스 크기를 변수로 하여 화염분출이 연소에 미치는 영향을 파 악하였다. 또한 이들의 결과를 부실쪽에서 점화하는 경우와 비교하여 주연소실쪽 점 화방식의 화염분출효과를 평가하였다.
