20.500.12556/DKUM-61788 Numerična simulacija procesa vbrizgavanja ob uporabi biogoriv Numerical simulation of injection process using biofuels Biogoriva so, v deležu ali v celoti, zanesljivo in ekonomično nadomestilo konvencionalnim fosilnim gorivom. Vseeno pa lahko specifične lastnosti biogoriv predstavljajo težavo glede kompatibilnosti vbrizgalnih sistemov z gorivi. Sodobni programski paketi omogočajo računalniško simulacijo procesa vbrizgavanja, različnih modelov vbrizgalnih sistemov ter uporabo različnih goriv in njihovih mešanic. V diplomskem delu so bile opravljene simulacije mehansko krmiljenega procesa vbrizgavanja, ob uporabi čistega dizelskega goriva, čistega biodizelskega goriva ter mešanic obeh goriv s petnajst odstotnim deležem etanola. Rezultati simulacij odkrivajo vpliv lastnosti biogoriv na karakteristike procesa vbrizgavanja, prav tako pa se dobro ujemajo z rezultati eksperimentalnih raziskav. Biofuels are, fully or partially, reliable and economical substitute to conventional fossil fuels. However, specific properties of biofuels can represent problems regarding compatibility of injection systems and injected fuels. Modern computer-aided software provides computer simulations of injection process, using variety of injection system models and variety of fuels or their blends. In diploma research were performed the simulations of mechanically controlled injection process by using pure diesel fuel, pure biodiesel fuel and 15 % blends of ethanol in mentioned fuels. Simulation results reveal the influence of the biofuel properties on injection process characteristics, moreover, the results are in accordance with experimentally obtained results. gorivo biogorivo vbrizgalni sistem numerične simulacije lastnosti goriv karakteristike vbrizgavanja fuel biofuel injection system numerical simulations fuel properties injection characteristic true true false [S.
