Thermodynamic Investigations of a Turbocharged Homogeneous Charge Compression Ignition (HCCI) Engine Running on Wet Ethanol

To study the performance of a turbocharged wet ethanol operated homogeneous charge compression ignition (HCCI) engine-based thermal system at various operating parameters, thermodynamic investigations were conducted. The goal of this thermodynamic analysis is to see how the compressor pressor ratio, ambient temperature and equivalence ratio affect the thermal and exergetic efficiencies of a wet ethanol powered turbocharged HCCI engine. According to a detailed performance analysis of a wet ethanol powered HCCI engine-based system using the above discussed operating parameters, raising the compressor pressure ratio and equivalence ratio increases thermal and exergetic efficiencies. On the other hand, as the ambient temperature increases, the energetic and exergetic efficiency of the turbocharged HCCI engine operating on wet ethanol decrease.
