Original abstract
This article deals with modelling of the fuel flow out of the injection nozzle into the combustion chamber of a heavy-duty diesel engine with direct injection. More specifically, the article presents the results and comparison of numerical simulations of the fuel flow out of the six-outlet injection nozzle, which were obtained by applying the discrete element method and computational fluid dynamics. Furthermore, an experimental verification of the results is also presented, using the recording of the injection process, acquired in laboratory conditions.

Tento článek se zabývá modelováním proudění paliva ven ze vstřikovací trysky do spalovacího prostoru vznětového motoru s přímým vstřikováním určeného pro těžký provoz. Konkrétně, článek prezentuje výsledky a porovnání numerických simulací proudění paliva ze šesti otvorové vstřikovací trysky, které byly získány za použití metody diskrétních prvků a výpočtové metody pro simulaci proudění tekutin. Kromě toho, je také prezentováno experimentální ověření výsledků pomocí záznamu procesu vstřikování získaného v laboratorních podmínkách.
