The effects of steam injection on the performance and emission parameters of a Miller cycle diesel engine

Comprehensive performance analyses and optimization of the irreversible thermodynamic cycle engines (TCE) under maximum power (MP) and maximum power density (MPD) conditions

“…Zhu et al [65] parameters such as miller cycle ratio, pressure ratio, stroke ratio, cut-off ratio, exhaust temperature ratio, isentropic temperature ratio of the compression process, cycle temperature ratio and cycle pressure ratio on the performance and power density of the cycles have been analyzed and the optimal performance and design parameters under MP, MPD and MEF conditions are defined by considering the internal irreversibilities originating from the adiabatic compression and expansion processes. If the previous studies [1,4,5,15,[17][18][19][20][26][27][28][29][30]32,[34][35][36][40][41][42][43]46,47,[49][50][51]52,57] are investigated, it is seen that the characteristics of the performance curves are similar to presented study. Also a validation of theoretical model presented in this study has been provided comparing with a previous study [52].…”

“…They [56][57] experimentally and theoretically investigated the performance and NOx emissions of miller cycle diesel engine with steam injection method and also they [58] theoretically determined the optimum steam temperatures and mass ratios based on thermo dynamical analyses for turbocharged internal combustion engines. Durmayaz et al [59] reviewed the optimization studies of thermal systems by considering different objective functions based on FTT and thermo economics.…”

Investigation of the influences of steam injection on the equilibrium combustion products and thermodynamic properties of bio fuels (biodiesels and alcohols)

“…There are various methods so as to reduce NOx emissions such as exhaust gas recirculation (EGR), the water usage methods (direct water injection (DWI), fumigation, emulsion). Since EGR decrease the engine performance considerably [31,32], classical water usage methods lower the quality of lubrication oil and increase the attrition rate of moving parts of the engine [33], recently, steam injection method has been proposed and used by engine researchers [33][34][35][36][37][38][39][43][44][45] in order to reduce NOx emissions and improve the engine performance.…”

Comparative performance analyses of irreversible OMCE (Otto Miller cycle engine)-DiMCE (Diesel miller cycle engine)-DMCE (Dual Miller cycle engine)

“…In the results, NOx decreased up to 75% compared to standard engine. Gonca et al [51] applied the MC and steam injection method together into a single cylinder, DI diesel engine. The modified engine produces less NO emissions compared to original engine.…”
