A low emission pre-vaporization pre-mixing lean (PPL) combustor for a 100 kW automotive ceramic gas turbine (CGT) has been developed to meet the Japanese 10-15 mode regulations without after treatment such as catalysts. Emission characteristics of the combustor on a test bench, and installed in the engine were obtained under steady state and transient conditions. Transient NO_x characteristics were dominated by the primary air ratio in the same manner as the steady state NO_x characteristics. Empirical equations for NO_x and CO characteristics were proposed for the PPL combustor. NO_x, CO and THC emissions for the Japanese 10-15 mode were predicted, and all of them fully satisfied the emission targets.
