Hm, prosto mi deluje neverovatno i da zamislim da Ferrari ima besprekoran motor a Mercedes problem sa motorom. Koji je izvor ovog teksta?

Ne vidim zasto bi Mercedes imao problem pa oni su proslu sezonu zavrsili sa 4 PU maltene .Pa da ne diraju nista i da popiju jednu kaznu za 4 PU i na konju su.Mercedes nije Honda da moze da zasere

Da se vratimo mi klipovima i hodu - ako moze :)

Bore/stroke ratio
Bore/stroke is the more commonly used term, with usage in North America, Europe, United Kingdom, Asia, and Australia.
The diameter of the cylinder bore is divided by the length of the piston stroke to give the ratio.

An engine is described as oversquare or short-stroke if its cylinders have a greater bore diameter than its stroke length, giving a bore/stroke ratio greater than 1:1.
An oversquare engine allows for more and larger valves in the head of the cylinder, higher possible RPM by lowering maximum piston ring speed and lower crank stress due to the lower peak piston acceleration for the same engine speed. Due to the increased piston and head surface area, the heat loss increases as the bore/stroke ratio is increased. Thus an excessively high ratio can lead to a decreased thermal efficiency compared to other engine geometries. Because these characteristics favor higher engine speeds, oversquare engines are often tuned to develop peak torque at a relatively high speed. The large size/width of the combustion chamber at ignition can cause increased inhomogeneity in the air/fuel mixture during combustion, resulting in higher emissions.
The reduced stroke length allows for a shorter cylinder and sometimes a shorter connecting rod, generally making oversquare engines less tall but wider than undersquare engines of similar engine displacement.

Extreme oversquare engines are found in Formula One racing cars, where strict rules limit displacement, thereby necessitating that power be achieved through high engine speeds. Stroke ratios approaching 2.5:1 are allowed, enabling engine speeds of 18,000 RPM while remaining reliable for multiple races.

A zasto u ovoj temi raspravljamo o klipovima.Zar ne bi bilo mnogo bolje da ovo premestis gde sutra moze mnogo lakse da se nadje.

Zato sto raspravljamo o F1 motoru, a o klipovima ce posebno biti napravljena tema kao i za jos stvari u sekciji tehnologija.

E onda izvini za ovo pitanje ali kad se sutra ocekuje Ferrari i Mercedes?

Ferrari u 15.00CET a Mercedes verovatno ranije. Provericu pa cu okaciti
P.S.
Mercedes navodno oko 11.00H

Postoji priča da će sutra Ferari prezentirati bolid bez sponzorskih nalepnica zbog nekih svađa sa Libertijem
