Ograniczanie zużycia paliwa w modułowym hybrydowym układzie napędowym samochodu

The paper describes initial stages of designing Modul Hybrid drive system. This type of drive uses traditional electric unit consisting of battery, starter and alternator. This system, appropriately adapted, for instance by increasing its overall rated power and supplementing it with novel energy control procedures, may operate in a manner similar to hybrid car drives. A supercapacitor will be introduced as a new component, its role is to operate as energy accumulator for IC engine start-ups. Automobile Stop & Go System in Modul Hybrid Drive makes it possible to switch off IC engine automatically when vehicle stops (e.g. at red light or in traffic hold-ups) and then to switch it on quickly again. This action makes it possible to decrease fuel consumption and carbon dioxide emission, particularly in towns. Results of supercapacitor performance during IC engine start-ups are presented in this paper. Energy consumption at start-up has been calculated together with start-up time. Magnetti Marelli-Denso E80E car starter used in Fiat Palio has been used in tests, this starter is rated at 12 V 1,0 kW. Several tens of IC engines start-ups were conducted, with starter supplied from traditional standard lead-acid battery (Centra Futura 055 290, C20 = 55Ah); next, similar tests were run using supercapacitor (MAXWELL BPAK 15V 58F.).
