The combustion characteristics of natural gas are studied in a constant volume bomb at various equivalence ratios, initial temperature and pressure. The study shows that with an increase of initial temperature, the normalized mass burning rate increases and the flame developing duration and combustion duration decrease. With an increase of initial pressure, the normalized mass burning rate decreases obviously, the flame developing duration and combustion duration increase at various equivalence ratios. For both lean and rich combustion, the effects of initial temperature and pressure on combustion duration are quite obvious.
