20.500.12556/RUL-106216 Simultaneous particulate matter and nitrogen oxide emission reduction through enhanced charge homogenization in diesel engines In the presented study, low temperature combustion was established with a direct injection of diesel fuel being a representative of high reactivity fuels and tire pyrolysis oil being a representative of low reactivity fuels. Tire pyrolysis oil was tested as a potential waste derived fuel for low temperature combustion, as it features diesel-like physical properties and lower cetane number compared to diesel fuel. The goal of this study was determination of suitable injection strategies and exhaust gas recirculation rates to explore potentials of both fuels in reducing emissions in low temperature combustion modes. It was demonstrated that relatively small changes in the engine control strategy possess the potential to significantly improve nitrogen oxide/particulate matter trade-off with minor effect on engine efficiency. In addition, low temperature combustion was for the first time successfully demonstrated with tire pyrolysis oil fuel, however, it was shown that lower reactivity of the fuel is by itself not sufficient to improve nitrogen oxide/ soot trade-off compared to the diesel fuel as entire spectra of fuel properties play an important role in improving nitrogen oxide/soot trade-off. This study thus establishes relations between different engine control strategies, intake manifold pressure and exhaust gas recirculation rate on engine thermodynamic parameters and engine-out emissions while utilizing innovative waste derived fuel that have not yet been analysed in similar combustion concepts. compression ignition engine low temperature combustion partially premixed combustion tire pyrolysis oil engine control combustion parameters emissions kompresijski vžig nizko-temperaturno zgorevanje zgorevanje delno homogenizirane zmesi pirolizno olje iz pnevmatik krmiljenje motorja zgorevalni parametri onesnažila true false true Angleški jezik Slovenski jezik Članek v reviji 2019-02-12 14:11:36 2019-02-12 14:11:39 2025-02-25 08:38:42 0000-00-00 00:00:00 2018 0 0 Str. 2039-2052 nr. 5 Vol. 22 2018 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.43(045) 0354-9836 10.2298/TSCI180131259Z 16267803 43417089 RAZ_Zvar_Baskovic_Urban_i2018.pdf RAZ_Zvar_Baskovic_Urban_i2018.pdf 1 3313111CA13CF9DF04DCE795232D4297 52878a2e78b62ced4706626e66aecf7989c7a68eefa827eb0d0d97d32fe65119 4debf366-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116968 http://www.doiserbia.nb.rs/Article.aspx?ID=0354-98361800259Z#.XGLGlLgo9aQ 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116967 Fakulteta za strojništvo 0 0 0
