Najničja poraba goriva je v območju največjega navora. Ko kupuje? nov avtomobil pa teh podatkov nimaš. tudi v prospektih teh podatkov ni. Zanima me ?e ima kdo diagram (podatke), ki prikazuje razmerje med obrati motorja in hitrostjo avtomobila glede na izbrano prestavno razmerje. Ni vseeno ali voziš npr. 90 km/h v 4. ali 5. prestavi.

C4 picasso 2.0 16V
Max. output: 139.9 PS (138 bph) (102.9 kW) @ 6000 rpm
Max. torque: 200 Nm (147.5 lbft) (20.3 kgm) @ 4000 rpm
C4 picasso 2.0 HDI
Max. output: 108.4 PS (107 bph) (79.7 kW) @ 4000 rpm
Max. torque: 240 Nm (177 lbft) (24.4 kgm) @ 1750 rpm
C4 picasso 1.8 16V
Max. output: 125.7 PS (124 bph) (92.4 kW) @ 6000 rpm
Max. torque: 170 Nm (125.3 lbft) (17.3 kgm) @ 3750 rpm
Andrej je treba dobro prebrat kaj močakar sprašuje. Prestavna razmerja dobiš na homologacijskem karton?ku, kar po moje ne bi smel biti problem pri trgovcu z novimi vozili ali pa kje po netu. Najničja poraba pa je dokazano okoli 70 km/h v IV prestavi - vsaj za veliko večino vozil to velja (zračni upor).
Eh, ti tovarniski podatki pa tudi ne drzijo, vsaj za HDI ne.
Moj HDI ima (izmerjeno na valjih!) najvisji navor pri 3.100 vrtljajih in tam nikakor nima najnizje porabe. Za doseganje le-te, se mora vrteti med 2.000 in 2.300 obrati na minuto, saj je tam izkoristek turbine kar najvecji ... Pri visjih hitrostih pa pride do izraza predvsem zracni upor, ki negativno vpliva na porabo goriva, tako kot je ze Cojko omenil.
Nekaj takega sem pred leti meril na mojem AX-u 1.1. (seveda je tabela pribli?nih vrednosti, saj ne morem prav natan?no izmerit ne hitrosti ne obratov)
AX 1.1 (40kW ima največji navor pri 3200 obrati in največjo moč pri 5800 obr)
Se pravi da bi imel najničjo porabo pri cca 88km/h v 4 prestavi?
Ali v 2-gi pri 50 km/h?
Ne vem ?e bo glih tako.
Podatki so najbolj pregledni v grafi?ni obliki.
pripravil sem graf z izmišljenimi podatki.
drži pa da je najničja poraba v območju največjega navora (pri HDI je to med 1750 do 1900 prm) in ne pri največji moči!

na valju so verjetno merili moč motorja
Ta vikend sem meril porabo na V6. povprečna hitrost pri približno 3500 obratih v 5.prestavi je med 125-135 po GPS in 135-145 po ?tevcu. Na 833 km progi je pojedla 8,64l na 100 km. Vmes so bila tudi podro?ja z intenzivnej?o vožnjo, klanci od Bologne do Firenz in do 200 na uro po nekaj kratkih skritih odsekih. Mestna vožnja je ?e dalj časa okoli 10/100. Stanje motorja je optimalno, kilometrov je ene 275.000km, ELF Excellium LDX 5w40, sve?e NGK bo pa treba zamenjat.
Prva liga... ljudje pa dizle kupujejo. Danes je glih kolegu ko je bil pameten ko satan turbina na dci raztrgalo... 1000? pa je. Jao.:Red-Wink:
