Recently many studies related to the lean-burn technology of gas engine have been carried out to improve fuel enconomy by minimizing the reduction of power output and to reduce exhaust emisson. Lean combustion is effective way of improving fuel economy and reducing emission gas of S.I. It is investigated that the effect of initial pressure, excess air ratio and ignition time on combustion performance and exhaust emission characteristics of stratified pattern in a cylinderical constant volume combustion chamber. Gas Chromatograph is used to determine the CO₂, CO. O₂, UHC concentrations in the chamber. The measurement of methane-air mixture are performed excess air ratio varing from 1.1 to 1.4 . As a result, in the case of RI shows better exhaust emission characteristics. Especially RI condition reduced more CO₂ and UHC concentration than that of HI or LI conditions. In case of Inhomogeneous conditon, UHC and CO₂ is reduced in accordance with increasing initial charge pressure but O₂ is reduced. Especially, when the excess air ratio of initial charge mixture is 3, UHC and CO₂ is redued compared to any other conditons.<br/>
