“…Considering HTL, FL and IIL and fixing the cycle maximum temperature, Yang and He et al [242] [96,[238][239][240][241][242][243][244][245][246], obtained the power output and efficiency performance characteristics of an irreversible Miller cycle, and investigated the influences of their design parameters on cycle performance. Considering HTL, FL and IIL and fixing the cycle maximum temperature, Ge [84] used the VSH model established in [87,96,[238][239][240][241][242][243][244][245][246][247][248][249], studied the optimum EF performance of an irreversible Miller cycle, and analyzed the influences of the three losses and VSH on cycle EF performance.…”

Abstract:On the basis of introducing the origin and development of finite time thermodynamics (FTT), this paper reviews the progress in FTT optimization for internal combustion engine (ICE) cycles from the following four aspects: the studies on the optimum performances of air standard endoreversible (with only the irreversibility of heat resistance) and irreversible ICE cycles, including Otto, Diesel, Atkinson, Brayton, Dual, Miller, Porous Medium and Universal cycles with constant specific heats, variable specific heats, and variable specific ratio of the conventional and quantum working fluids (WFs); the studies on the optimum piston motion (OPM) trajectories of ICE cycles, including Otto and Diesel cycles with Newtonian and other heat transfer laws; the studies on the performance limits of ICE cycles with non-uniform WF with Newtonian and other heat transfer laws; as well as the studies on the performance simulation of ICE cycles. In the studies, the optimization objectives include work, power, power density, efficiency, entropy generation rate, ecological function, and so on. The further direction for the studies is explored.

“…Capaldi [47] designed a 10 kW electric power micro cogeneration plant based on Atkinson/Miller cycle ICE with an extended expansion ratio, capable of a higher global efficiency and low gaseous emissions and he investigated the overall performance of it. Lin et al [48] performed an analysis for a fourstroke free-piston engine running with irreversible air standard MC by using finite-time thermodynamic. Benajes et al [49] applied the EGR (exhaust gas recirculation) to decrease oxygen concentration and the MC by advancing the intake valve closing angle into a heavy duty diesel engine to carry out low temperature combustion concept.…”

“…Gonca et al [13] studied the performance analysis based on the * e-mail: Rahim.Ebrahimi@gmail.com power output, thermal efficiency, maximum power output and maximum thermal efficiency for an air-standard irreversible dual-Miller cycle with late inlet valve closing version which covers internal irreversibility owing to the irreversible-adiabatic processes. Lin et al [14] evaluated the performance of an irreversible air standard Miller cycle in a four-stroke free-piston engine by using finite-time thermodynamic. In the model, the relation between the internal irreversibility described by using the compression and expansion efficiencies, the specific heat of the working substance depending on its temperature, the heat transfer loss as a percentage of fuel's energy and the friction loss computed according to the mean velocity of the piston is considered.…”

Performance analysis has been carried out for air-standard Miller engine using second law analysis. The relations of the second law efficiency versus compression ratio, the second law efficiency versus first law efficiency as well as the exergy versus compression ratio are obtained. The results show that the curve of second law efficiency versus first law efficiency is a parabolic-like one. The results also show that, throughout the compression ratio range, the second law efficiency increases when the expansion-compression ratio increases.
