| 초록 |
A cylindrical constant volume combustion chamber was used to investigate the exhaust emission characteristics of homogeneous charge, stratified pattern and inhomogeneous charge under various conditions using gas chromatography. In the case of homogeneous charge condition, the CO2 concentration is proportional to excess air ratio and overall charge pressure, the O2 concentration is proportional to excess air ratio and the UHC concentration is inversely proportional to ignition time and overall charge pressure. In the case of stratified pattern, the RI(rich injection) condition shows better exhaust emission characteristics, especially : CO2, than that of HI(homogeneous injection) or LI(lean injection) conditions. In inhomogeneous charge conditions, when initial charge pressure is increased, CO2 and UHC concentration is reduced but O2 concentration is increased. And when the excess air ratio of initial charge mixture is 3.0, UHC and CO2 concentration show lowest values.{{br}} |
