Lud zbunjenog:
 

 

Ne tako davno Ferari je bio najglasniji protivnik V6 turbo hibrida (barem medju proizvodjacima - medju timovima to je konstantno RBR), kao njih ne zanimaju ni struja ni turbo vec samo veliki atmosferski motori, a evo sada kad im je konacno proradio motor okrecu curak naopako i sada bas oni ne daju da se odstupi od hibridne tehnologije.

 

Nemojte me pogresno shvatiti, mislim da je greska ponovno menjanje pravila oko motora jer taman smo poceli da vidimo sustizanje medju proizvodjacima i ako se sada promene pravila samo cemo ponovo dobiti dominaciju jednog proizvodjaca dok se ostali ne snadju. Ono sto treba F1 je ogranicavanje cene po kojoj proizvodjaci moraju da prodaju motore svojim klijentima, a ne novo bacanje para na razvoj potpuno drugacijih motora.

 

 

Jeste Ferrari bio protivnik elektricnih bolida, struje itd. ali vrlo ubrzano se od strane veoma uticajnih drzava najavljuje zakonska regulativa koja ce za 20/30 godina zabraniti ili drasticno smanjiti proizvodnju vozila na sagorivanje, tako da je Marchionne tu neko ko mora da prati te trendove ili zatvori fabriku. Trece opcije nema.

 

Fino covjek kaze: "Either we do something clever and consistent with the development or we forget it. These easy solutions to remove the hybrid parts of the engine, or to bring back the 12 cylinder aspirated engines, are in the past," Marchionne added.

Zanimljiv osvrt na komparaciju razvoja PJ počev od VN VB prošle godine na VN Australije do VN Mađarske:

Jako sam skeptican prema svim ovim dijagramima...

Mercedes is close to to producing a Formula 1 engine that can deliver a power output of 1000bhp, according to its engine boss Andy Cowell.

Mercedes has dominated F1's V6 turbo hybrid era, clinching four successive double world championships.

Power unit development has been such that in 2016 Cowell said Mercedes had exceeded 900bhp and now says it is on course to break the 1000bhp barrier.

"We're close," Cowell told Autosport. "I'm sure that'll happen at some point."

This year, Mercedes' engine hit a landmark achievement on the dyno when it broke the 50% thermal efficiency barrier for the first time.

Its progress is thought to have made its M08 EQ Power+ the most efficient racing engine ever.

Thermal efficiency, which is calculated on the amount of useful energy that can be produced from a given amount of heat input, has become a key focus for modern engine builders.

In F1, it is particularly important because of the strict fuel-flow limit rate of 100kg/hour.

When asked how long it will take until 50% thermal efficiency is transferred from the dyno to the track, Cowell said: "It's an answer for the early part of the next year.

"We need to see how the power unit development goes through the winter and our prove-out goes through the winter, and it's a balance with the car as well.

"There are engines running on the dyno - that's one thing.

"When you go to total car lap time, that's the bit where there's work being done to improve the technology on the car to enhance both aerodynamic and power unit performance.

"Let's see how it all works out."

Mercedes' first turbo-hybrid engine, introduced in 2014, had an efficiency rate of 44%.

 

Ne tako davno, verovalo se da motori u praksi ne mogu preko 30% termicke efikasnosti (najefikasniji su bili na nessto preko 20%). Evo sada probijamo 50%, i to proizvodeci 1000 KS iz 1,6 l zapremine sa protokom goriva ogranicenim na 100 kg/h.

 

A ljudi progutali Bernijevu propagandu o "ustrojenim" motorima.

 

Ovi sadasnji motori su apsolutno neverovatni, F1 bolidi nikada u istoriji nisu bili brzi (ogranicavaju ih jedino gume), a mi slusamo kuknjavu o "dosadnim" motorima, vozacima taksistima, nedostatku buke i slicne nebuloze.

FIA president Jean Todt has resurrected the idea of a 'global engine' that could be used in both Formula 1 and other motorsport series.

The concept was previously proposed in the late 2000s, when the FIA commissioned British engineering consultancy Ricardo to investigate the potential for a common rules package to create a base engine that could be adapted for use in as many as 11 major series around the world.

The 2009 report proposed that championships ranging from F1 and IndyCar to single-seater ladder categories, rallying, touring cars and prototype sportscars could use versions of the same engine, but the concept fizzled out amid concerns over cost and practicality from the targeted championships and manufacturers.

But with huge investment needed to produce engines for the current hybrid F1 regulations, Todt suggested reviving the global rules concept could be attractive.

"Probably what we should say, which is not easy as well, is could we use this [F1] engine in other categories of motorsport?" he said.

"At the moment each category of motorsport has its own single regulations, so probably we should try to see if we can have some synergies."

Todt highlighted the World Endurance Championship's LMP1 class as a candidate for sharing engine rules with F1, saying grand prix racing's move towards longer-life engines made it more practical for its technology to be used in long-distance sportscar racing too.

"We have the endurance championship with LMP1," said Todt.

"We have completely different engines, so would it make sense to anticipate a future for the endurance championship using this synergy - which incidentally is covering the same kind of mileage."

The WEC is currently assessing options for future rules packages as it reacts to Porsche and Audi's departures from LMP1.

Though a move towards road-car styling has been mooted for 2020/21, a major change in engine philosophy is considered unlikely as privateers have been promised rules stability.

Motorsport.com understands that Todt's 'global engine' idea has not so far been formally suggested to LMP1 teams.

F1 and top-level sportscar racing's last attempt to share engine technology proved ill-fated, when Group C's move towards F1's 3.5-litre engines led to the decline and eventual demise of the World Sportscar Championship ahead of the 1993 season.

 

Ideja da se isti ili slicni motori mogu koristiti u vise razlicitih kategorija je dobra sa stanovista da moze da pruzi veci izbor snabdevaca i time pruzi priliku za upliv sveze krvi i novih ideja, ali ako su specifikacije pogresno odabrane moze da ima i katastrofalne posledice, da podigne cene i otera sve proizvodjace. Meni se cini da se ovome pristupa pomalo naopako, i umesto pokusaja da se napravi jedan motor koji ce onda (uz male varijacije) biti nametnut svima da bi mozda trebalo pokusati sa legalizacijom motora vrlo razlicitih konfiguracija iz razlicitih serija za vise od jedne serije. Zasto ne bi u F1 bili legalni i Indikar motori (da zanemarimo za trenutak cinjenicu da im fali 250-tak konja da budu konkurentni) uz ove sadasnje F1 motore? Zasto ne bi ovi sadasnji F1 motori ovakvi kakvi su bili legalni u WEC uz tamo vec postojece motore? I tome slicno.

Cosworth admits it is "unlikely" to return to Formula 1 as an independent engine supplier, and needs external backing to come back for the new engine regulations.
