Abstract：JC15T type engine is a natural gas engine with closed-loop air-fuel ratio control. In this paper, the design and development of this natural gas engine have been optimized by optimizing the calibration of EGStrim control system and matching tests on JC15T type natural gas engine. EGStrim control system adopts advanced closed-loop air-fuel ratio control technology, which enables the engine to always operate under the optimum excess air fuel ratio setting. The data acquisition, measurement, control and analysis of JC15T type gas turbine performance parameters have been completed by the test of EGS trim control system. The results of the test indicate that the performance and emissions of the JC15T type natural gas engine meet the design requirements, and also indicate that the calibration of the control system parameters is effective.
