Abstract
Cilj ovog rada je bio simulacijski pokazati potencijal sustava nasumiĉnog iskljuĉivanja cilindara kod Ottovih motora. Prvenstveno je bilo potrebno odabrati Ottov motor na kojem će se bazirati simulacijski model. Nadalje je bilo potrebno kalibrirati komponente simulacijskog modela kako bi simulirani motor imao što sliĉniju radnu karakteristiku. OdraĊena je obrada simulacijskih podataka kako bi se dobila specifiĉna efektivna potrošnja goriva za normalan rad motora koja je kasnije korištena kao polazna toĉka za evaluaciju efikasnosti rada motora s DSF (eng. “Dynamic skip fire”) sustavom. Nakon simuliranja normalnog rada motora potrebno je bilo prilagoditi simulaciju za DSF naĉin rada. Kontrolom razliĉitih gustoća paljenja opisan je naĉin rada motora u praznom hodu kada je isti opremljen DSF sustavom. Daljnji interes ovog rada nalazio se u analizi razdiobe energije kod normalnog rada motora i onog sa nasumiĉnim iskljuĉivanjem cilindara. Naposljetku se izvršilo definiranje strategije rada motora kod djelomiĉnih opterećenja sa ciljem postizanja minimalne potrošnje i maksimalne uĉinkovitosti uz opisivanje preventivnih mjera za sprijeĉavanje detonantnog izgaranja.
Abstract (english)
Aim of this paper was to show dynamic skip fire system potential in Otto cycle engines. Firstly engine on which simulation model would be based had to be chosen. Next was calibration of all simulation components so simulated engine’s working carakteristic was as close as possible to the real engine. By analysing simulation data break specific fuel consumption for normal working engine was defined which would be used as starting point in evaluating the efficiency of DSF equipped engine. After simulation of normal working engine was complete, simulation had to be altered in such a way it could accommodate DSF technology. Engine working at idle load had been described by controlling fireing density of cylinders. Further interest of this paper was distribution of termal energy in normal working engine compared to DSF working engine. In the end engine control strategy was defined with emphasis on maximizing engine efficiency at partial loads alongside engine knock prevention strategy.
