Exergy Analysis of In-Cylinder Combustion and Exhaust Processes in Internal Combustion Engines
The exergy analysis is a powerful tool for investigating thermodynamic irreversibilities and to identify pathways for improving efficiencies of energy systems, including internal combustion (IC) engines. The present study provides a two-pronged methodology to increase the work output and FCEs of IC engines. First, a detailed exergy analysis of in-cylinder phenomena in an IC engine of in-cylinder phenomena was developed and performed in an IC engine operating on an advanced combustion strategy (i.e., diesel-ignited methane dual fuel low temperature combustion (LTC). Second, a combined, experimentally driven, computational exergy analysis methodology of exhaust flows to characterize crank angle-resolved exhaust exergy was introduce and implemented on a diesel engine.
