Abstract
It is well known that the stratified charge combustion has many kind of advantages to combustion characteristics, such as higher thermal efficiency and less CO levels than conventional homogeneous mixture combustion. Although this combustion can achieve the low fuel consumption, it produced the high unbumed hydrocabon and soot levels because of heterogeneous mixture distribution in the combustion chamber. Moreover, it has a lot of possibility of low output and misfire if the mixture gas can not be concentrated around the spark plug. In this p환)er,fundamental studies for stratified combustion were carried out using a constant volume combustion chamber. The effect of mixture distribution on the flame propagation speed in the chamber were examined by changing the fuel supply method. A maximum volumetric burning velocity (Sv)^, which closely correlates with (dP/dt)^,was proposed as the stratification degree. Using this concept, we found that the higher stratification degree produced the wider area of stoichiometric mixture and this resulted in higher burning velocity as well as less amount of unbumed fuel.
