Investigations on the Potential of Miller Cycle for Performance Improvement of Gas Engine

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 investi…
