Injection process characteristics were measured with a Friedmann-Maier injection system test bench using different fuel blends. The spray was injected into the pressurised chamber at 40 or 60 bars and filme dwith a high-speed camera. The image acquisition and processing system was developed in order to determine the spray-cone angle and the penetration length during different injection regimes. The results obtained from the experimental study show that differences in the chemical and physical characteristics of the alternative fuel blends used influence the spray characteristics (spray cone angle and penetration length). For wider usage of alternative fuels, further investigations need to be madeČlanek predstavlja eksperimentalno analizo razvoja curka alternativnih goriv. Karakteristike vbrizgavanja so bile izmerjene na napravi za izvenvozilsko testiranje tlačilk Friedmann-Maier, ob uporabi različnih mešanic goriv. Vbrizgavanje curka v namensko tlačno komoro, s tlakom 40 ali 60 barov, je bilo posneto s hitro kamero. Za lažjo določitev dolžine in kota curka je bila razvita posebna metoda obdelave slik, posnetih s hitro kamero. Rezultati študije so pokazali, da kemijske in fizikalne lastnosti uporabljenih alternativnih goriv vplivajo na karakteristike vbrizganega curka (kot in dolžina). Za širšo uporabo alternativnih goriv, so potrebne nadaljnje raziskaveTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Mariboru, Fakulteta za energetiko
