Combustion Engines
2015 R. 54, nr 3 19--33
EN The aim of this study was to determine possibilities of the soot and NOx emissions reduction from an existing heavy-duty compression-ignition (CI) engine based only on in-cylinder techniques. To that end numerical simulations of such processes as a multiphase fuel flow through injector nozzles, a li[...]

EN The possibility of achieving high thermodynamic efficiency brings opposed-piston (OP) engines back into interest of research centers. If made as 2-stroke, the possibility of unidirectional scavenging arises together with lower engine cost due to removal of unnecessary parts like camshafts or poppet [...]

Combustion Engines
2017 R. 56, nr 2 53--63
EN The aim of this study was to investigate a possibility of using gaseous fuels of a low calorific value as a fuel for internal combustion engines. Such fuels can come from organic matter decomposition (biogas), oil production (flare gas) or gasification of materials containing carbon (syngas). The ut[...]

EN In this paper a computational study on hexane flow in a fuel injector is presented. Large Eddy Simulation (LES) was used to capture the turbulent patterns present in the flow. The main aim was to investigate the cavitation phenomenon and its interaction with turbulence as well as the influence of in[...]

EN The aim of this study is to investigate a possibility of Compression Auto-Ignition (CAI) control in a turbocharged 2-stroke barrel type Opposed-Piston (OP) engine fueled with a gasoline. The barrel type OP engine arrangement is of particular interest for the authors because of its robust design, hig[...]

Journal of KONES
2018 Vol. 25, No. 4 141--147
EN The main aim of this study to reproduce methane combustion experiment conducted in a rapid compressionexpansion machine using AVL FIRETM software in order to shed more light on the in-cylinder processes. The piston movement profile, initial and boundary conditions as well as the geometry of the comb[...]
