Abstract
U radu je analizirano trenutačno stanje tehnike napajanja i pokretanja stroja s unutarnjim izgaranjem. U tom je okviru opisan način djelovanja sustava za pokretanje stroja s unutarnjim izgaranjem olovnog akumulatora, navedene su prednosti i nedostaci uređaja. Analiziran je način djelovanja električnog pokretača, te su navedeni njegovi osnovni dijelovi. Opisan je standardni sustav za pokretanje motora s unutarnjim izgaranjem, kao i njegov način djelovanja. Analizirano je kondenzatorsko dobivanje visokog napona. Analizirano je tranzistorsko pokretanje kroz simulaciju. Kod rezonantnog pokretanja analizirani su gubici sklapanja. Kroz međusobnu usporedbu su opisani različiti uređaji za pohranu energije, i povezivanje naponskih razina u automobilima. Analizirana je litij ionska baterija, te su navedene njene prednosti i nedostaci. Predložena je zamjena kolektorskog stroja kod električnog pokretača bezkolektorskim strojem. Prikazani su rezultati simulacije dvosmjernog istosmjernog pretvarača uz opis djelovanja i mogućnost primjene kod suvremenih automobila. Opisan je rad superkondenzatorskog spremnika energije i električnog pokretača kroz praktičan rad i prikazani su rezultati čime je pokazana mogućnost zamjene olovnih akumulatora kod različitih strojeva s unutarnjim izgaranjem. Predstavljeno rješenje zamjene olovnog akumulatora kod konvencionalnih automobila koji koriste dizel kao gorivo uspoređeno je s rješenjem kod benzinskih strojeva s unutarnjim izgaranjem.
Abstract (english)
This paper deals with the current state of the art of batteries and supercapacitors for engine cranking. The fundamental principle of the lead-acid batteries has been evaluated. The principle of operation of the electric starter for the cranking of the combustion engine has been explained. Starting system of an internal combustion engine has been analyzed as well as its mode of operation. Capacitor discharge ignition with magnet rotation as its source has been described. Transistor controlled ignition has been displayed in the simulation. Resonant ignition has been analyzed as well as the switching losses. After the study of the starter system an alternative to the lead-acid battery cranking has been offered. At first a supercapacitor has been modeled, and referred to passive regulation and relations. Fundamental principle of the lithium-ion battery has been described with advantages and imperfections. Discharging of the supercapacitor energy storage device has been revealed through experiments. Results of the simulations of the bidirectional direct current converter have been demonstrated in order to show the possibility of connection of different storage elements in frame of DC buss in the automobile. Finally, lead-acid battery was replaced successfully with one or two supercapacitor banks. Such replacement has scientific and economic impact concerning automobile mass and fuel efficiency.
