영문 초록

The exhaust gas emissions of internal combustion engines such as HC, CO, NOX and smoke are directly related with the both temporal and spatial distribution of fuel air ratio in combustion chamber. The present paper provides a theoretical basis that the excess air coefficients of spray which is passing through a cylinderical tube coaxially become constant once the perifery of sprays get in touch with the tube wall. And it presents an equation to calculate the diameter of the tube in which the excess air coefficient of sprays become 0.8. Experiments manifested the fact that the radial fuel densitys of sprays that passing through the cylinderical tubes also become nearly homogeneous. A doughnut type pre-combustion chamber that will enables stratified charge combustion is recommanded as a measure of red using exhaust gas emissions coincidently.
