This paper reports the study of a conceptual gasoline Internal Combustion Engine (ICE) using scroll type rotary device rather than conventional piston as the main engine component. The proposed innovate engine adopts Humphrey Cycle to maximize the power performance of ICE. A performance comparison of the Humphrey Cycle, Otto cycle and Brayton cycle has firstly been conducted and studied. The effects of using different designed compression ratio under variable expansion ratio have been investigated, which identify the optimal operational conditions under different compression/expansion ratio of the engine. A case study has been conducted to study the performance of small scale scroll-type rotary ICE. Results pointed out under designed compression ratio from 2:1 to 10:,1 the effective energy efficiency of the scroll-type rotary ICE ranges from 0.41 to 0.55 and the effective power from the system ranges from 2.88 to 15.82 kW.
