Natural gas is a promising alternative fuel to meet strict engine emission regulations in many countries. The development of natural gas engines requires low emissions along with the demand for better fuel consumption and increased power ratings. In this study, a cylindrical Constant Volume Combustion Chamber(CVCC) was used to investigate the combustion characteristics under different ambient pressure and equivalence ratio. The rate of combustion variation, maximum combustion pressure, heat release rate and mass fraction of burned gas was evaluated in particular by chamber type, initial pressure and equivalence ratio. It also show that variation of flammability limits according to existence of pre-chamber. This result could provide lean burn condition by analyzing combustion characteristics with initial condition.
