Kdo pa pravi, da je navor pomembnejši od moči????
A ste se kdaj vprašali, koliko ima firmula 1 navora? Sploh ga nima ne vem koliko dosti, pa ima kljub vsemu nenormalen pospešek. Enako je s skoraj vsemi dirkalniki. Poglejte malo koliko ima Mitsubishi EVO navora, pa ima kljub vsemu zavidljiv pospešek in se lahko vsi TDi- ji samo skrijejo v primerjavi.
Navor je res najpomembnejši, ampak samo če si avtoprevoznik in furaš tovornjak. Pri osebnem (še toliko bol pa pri športnem) vozilu je pomembnejša moč motorja.
Zelo težko je opredeliti razliko med navorom in močjo. Še nikjer nisem zasledil kakšne res lepe razlage o tem. Je pa res, da če se dosti let zanimaš za motorje z notranjim izgorevanjem in po možnosti študiraš strojništvo in imaš te stvari malce v krvi sčasoma razumeš zakaj je v določenih primerih boljše eno ali pa drugo.
Osebno menim, da dizli ne spadajo v športne avtomobile, kako tudi ne avtomatski menjalniki. Ko bodo v Formulo1 vgradili dizla in popolnoma avtomatski menjalnik bom morda spremenil mnenje.
Jaz pravim da je. Sem se peljal v novem MB E 320 (224 KM in 315Nm) in nato še v E 320 CDI (204KM in 500Nm) in je 320 CDI veliko večja zverina. V hrbru ne čutiš konjev če daš na gas veš..?ČUTIŠ NAVOR.
Tako tudi piše v tem članku: How do horsepower relate to the real power of a car?
If you, as the proud owner of a powerful car, say that it has 380 hp, you'll get many Oohs and Aahs but if you say that it's got 550 Nm of torque you'll hear just a '...?!' - if at all. In pol še neki razlaga...Conclusion
In order to know how a car accelerates, you have to have a look at the torque curve, the gearbox and take the weight of the car into account. Then - and only then can you expect a correct result. Knowing the horsepower figure is quite useless in such a case. Še to:
So no one measures the power of an engine directly. A dynamometer only measures torque which will be, related to the engine speed, converted into horsepower by the previous formula! That means that horsepower is more or less an imaginary unit and not something you could see, feel or measure. That may startle one or the other but that's really the way it is!
Čeprav se strinjam da verjetno res ne pašejo v kupeje (M3 naprimer...kaj je večji užitek kot ga držat do 8000rpm, kjer ima največ moči).
Aja še to k si neki govoru o formuli 1:
Another example: Take two 850CSi and replace one engine with one who has the same torque but whose torque peak is at 2000 rpm istead of 4000. When racing each other from a dead stop, the modified CSi will be faster off the line because its 550 Nm are available at 2000 rpm already, whrere the normal one has only 440 Nm.
After its peak the amount of torque rapidly falls and around 3000 rpm the driver of the modified CSi will have to shift into a higher gear because there he has more torque available. So engine power is sacrificed for speed. And now it's the stock CSi that blasts away because his opponent suddenly has just more than half the torque than in first gear, whereas he can go on in 1st until 6400 rpm. When the stock CSi shifts into second gear, the modified one will almost have to shift into third.
Did it look as if the modified car would win at first, everyone will see that it is better to have the torque peak at high rpm as soon as the modified car falls back rapidly. The BMW Formula-1 engine has about the same torque as the engine of the E46 M3. The M3 has its torque peak at 5000 rpm whereas the Formula-1 engine has its at about 16000. Let's guess who can have the accelerator pedal floored for a longer time...
