Abstract

To further improve thermal efficiency, Miller Cycle was applied to a turbo-charged 338 kW gas engine. Different methods of Miller Cycle were analyzed, including three Early Intake- Valve Closing (EIVC) methods and three Late Intake-Valve Closing (LIVC) methods. After the relatively suitable methods were chosen, the combination of the Miller Cycle and higher compression ratio was extensively investigated. The experimental results demonstrated that the combination of intake valves closing 40°CA earlier(EIVC40) and the compression ratio increasing to 13, the maximum thermal efficiency reached 47% and it is about 5~7% higher than the original cycle.
