Abstract:
V diplomskem delu je prikazana predelava modela motorja z direktnim vbrizgom goriva v valje (TGDI). Cilj je bil analiza možnosti za ohranitev zmogljivosti pri zmanjšanju prostornine s spremembo polnilnega sistema s turbino s fiksno geometrijo in obvodnim ventilom na turbino s spremenljivo geometrijo. V delu je opisano delovanje turbopolnilnika, TGDI motorja in simulacijski program AVL BOOSTTM. Predstavljena je predelava turbine in kontrola vseh parametrov modela v simulacijskem programu AVL BOOST. Pri analizi rezultatov je bila posebna pozornost namenjena ohranitvi tendence klenkanja in temperaturam v izpušnem sistemu. Raziskana je možnost uporabe Millerjevega cikla in zakasnitve vžiga. Millerjev cikel je smiselno uvesti v kombinaciji z mehansko gnanim kompresorjem.

Title:
Analysis of the influence of the charging system on the performance by downsizing tgdi engine
Abstract:
In the diploma work is presented modification of the turbocharged engine model with direct injection (TGDI). The objective was analysis of possibilities to conservation performance with downsizing and changes on turbine with fixed geometry and waste-gate to turbine with variable geometry. In work is described the operation of turbocharger, TGDI engine and simulation program AVL BOOSTTM. The turbine processing and control of all parameters in AVL BOOSTTM simulation program are presented. In the analysis of the results special focus was paid to maintaining knocking intensity and temperatures in the exhaust system. The possibilities of application of the miller cycle and retardation of the spark timing was investigated. Miller cycle is sensible to be introduced in combination with supercharger.
