Abstract

This study presents an analysis considering the effects of heat transfer loss and internal irreversibility due to adiabatic compression and expansion processes on the performance of an irreversible Dual-Atkinson cycle engine (DACE) under non-dimensional maximum power (MP), non-dimensional maximum power density (MPD) and maximum thermal efficiency (MEF) conditions. The effects of the inlet temperature, combustion constant and heat transfer constant on the engine performance are investigated. The results could be used by engine designers to optimize the performance of the internal combustion engines (ICEs). (C) 2016 Elsevier Inc. All rights reserved.
