This paper describes a simulating analysis of a small gas turbine engine with a reciprocating gasifier. In the previous paper, authors showed the possibility of one optimum system with the thermal efficiency of over 46% and the specific power of about 390 kW/ (kg/s). In the successive optimizing studies, another system with a thermal efficiency of more than 50% could be proposed, although the configuration was rather complicated. In this time, another system having more simple configuration, where the combustion gas was exhausted to the turbine during the recompression stroke instead of the expansion stroke, was introduced and some parameters were optimized by focusing on the effects of heat release rate and exhaust valve opening timing on the thermal efficiency and specific power of the system. Good results were obtained.
