[ARCHIVED] SCS General Discussion Thread

Maybe @plykkegaard that was on the IG Stories, but I don't remember seeing it. It would have been posted here too.

[plykkegaard]

Maybe

I know, no hard evidence
I went back page by page that's how confident I were
Anyway time will tell

Back on aerodynamics. It's not about speeding quickly or achieving a great top speed but saving fuel. Fuel economy and stability are important enough to invest on aerodynamics.

Part of this image was posted by SCS staff shortly after the news about Daimler were revealed
Unfortunately I am unable to find it atm, I'll keep looking

Should've been a casual post share. Honestly, there are many trucks which has to get into the game before that.

And thanks people, for the clarifications on the jake brake thing.

I'm normally pretty tolerant of "different" truck designs, to the point of liking the LoneStar a lot, but... uh, that just looks like a fat Stormtrooper. Who is complaining to the manager about being kicked out of the dining hall.

This is not praise.

European Trucks don't have engine brakes(jake brakes) they only use Exhaust brake or retarder (well technically jake brake is an exhaust brake,but it works differently, exauhst brake return the exuahst gazes to the engine to push on the piston while the jake brake interuppts the compression stroke by opening exhaust valve to brake the truck)

edit: before anyone says that they are similar in principle, the exhaust brake is a device mounted outside the engine (on the exhaust manifold) while jake brake is mounted on the cylinder head(on the camshaft to be precise).

Engine brakes on all European trucks are working on the same way(or somewhat similar MAN)as the ones in US and some of them in addition have that mounted device on the exhaust after the turbocharger,also you have to keep on mind that this days same engines are being installed to trucks in Europe and US.

Speaking of engine brakes...

How are they being applied in European trucks? I never saw a button or switch ingame when I use them. Should I activate "Automatic engine brake" for the most realistic experience?

[plykkegaard]

Back in the old days they a had trigger / button on the floor of the cabin (IRL)
In game my mouse is used for steering / look around, CC and engine - / exhaust - / jake brake, which is available is applied

Schematics (Volvo)

To those who think that aerodynamics don't matter at the speed that trucks go in Europe, they are also denying e.g. the effect of roof mounted deflectors and the aerodynamic advantage of conventional tractors over cabovers. There have actually been legal preparations to allow for more length if that is used to make a cabover more aerodynamic.

In fact cabover might be slightly better than some of the conventionals ones (especially the "classics" ones) on one thing aerodynamically speaking :

They move the air in front only once.

In comparison, a conventional will move the air a few times because of it's shape.

I remember that Robert Transport worked with Volvo Trucks NA and the PIT group a few year back to test the FH in the north american environment (Quebec only), and the difference in fuel economy between those FH that were equipped with a 460 HP engines and the VNLs were tested (a low-roof 630 with a 425hp engine and a 670 with a 455 HP engine) (both on the track and IRL) among other things (such as 24V electrical system vs 12 volts, etc...)

[harishw8r]

But isn't that also about the weight of the tractor? If I'm not wrong, cabovers should be lighter ...
