The Colors on the RPM Gauge.

[DarkSkyline16]

On the Scania for example, i know the Green RPM area is for best Torque and best MPG, and the Red is obviously the red line, but what is the Blue area for? It's between the Green and Blue.

Thanks

From what I saw ... (not some facts whatsoever) :

Green : like you said, this is eco mod, the best MPG and the best torque. But it is also where if you upshift, you will lose your momentum the most dreadfully possible, when it can be the most inadequate.

Red : like you said, lots of pain but no gain at all.

Blue : if you shift up here, your RPM won't fall into the green zone, you will keep your momentum and got a more fluid / soft driving, Even when I change my gears two by two, like most people do I think, the RPM would stay above the green zone

If I recall from an old Volvo FH12 training vidio I found. The blue is the best RPM to be in when using the engine brakes.

EDIT: Heres the vid. @ 4:00 watvh, he talks about the blue line on the RPM gauge. http://www.youtube.com/watch?v=DgcY1nbhDbQ

S10sleeper is on to something. The blue area is where the exhaust brake is the most effective, but in a couple of training videos I've seen drivers let the RPM dip into red for a few seconds, but then again it might be rugged Scania for you.

The Green color is for where the truck performes best over that the truck looses torque
the blue color is for the exhaust brake
and allways go over the green color before changing gears to make shure you not land to low on the green line
The game does a really bad job at the torque points its totaly wrong

One year later, I'm beginning to believe that there is some truth in that, this blue marker is only aesthetic and the exhaust brake is no more efficient specifically there. BTW, i do remember that at one point, it was called motor brake but changed through a patch to exhaust brake.

xD

Yeah, I should have been clearer since it's the gauge in the real truck I wrote about. It would appear to be at least a fairly flat efficiency coefficient in the game.

It is still called motor brake in Denmark

But then Denmark is not part of Europe by the standards of ETS2
i was like where is Denmark and where is Sweden and where is Finland all part of Europe but not in the ETS2

Get Promods' Scandinavia Map if you haven't. :) www.promods.net

think of a forthcoming DLC "going north" ;)

There is 2 kind of motor brake on a diesel engine, compression brake and exhaust brake. Since the first is really not " friendly " towards people, the 2nd one is the most common and in all likelyhood, SCS renamed it to avoid confusion, aka they did not integrate an awful motor brake.

[Hun73r]

normaly i use the retarder instead :D

A meaningless distinction, the game doesn't model any kind of real-world engine retardation system, it's just a simple and generic retardation mechanism that operates on engine RPM, so it's actually neither.

Proof ?

This is a long post but hear me out.

I have worked on diesel engines for years and truth be told they are very durable espically when compared to a gasoline engine meaning the block and other solid metal parts you still have to be careful of an over compression condtion that could blow seals.So far as the engine itself is concerned they can be pushed well into the red zone.Also remeber that engineers usually are very generious about labeling red zones for RPM they almost always extend the "red" RPM range a few hundred lower than it truly is.

Now the transmission is another ball game and this is the part that is actually far more prone to damge from over RPM than the diesel engine itself is.I used to work on Detroit Diesel powered generators in the USAF mostly inline 6 cylinders though we also had some more powerful V-8s these where the same models as used in trucks only no transmission instead they where hooked directly to an AC motor and soem units where hooked to a hydrulic pump or a compressor

In our case the senstive part was what ever the engine was connected to.And people that used our equipment they would try to mess with the governor which with our units kept the egines from over speeding they only had two points an idle and an operating speed.As has already been said a diesil engine typically reaches it optimum output long before it reaches max RPM or anywhere near it.These people that would try and tweek the govs to ahigher speed they incorrectly assumed that this would result in a higher output.the only thign it really did was place more strain on the unit conncted to the engine and sucked down more fuel.

Our units where all supercharged and some where tubro-superchanged.the superchager was needed do to the high compression ratio with out the blower the engine would not run well if at all under some condtions.Each unit had an emergancy shut off flap that when pressed closed off the supercharger blower thus starving the engine of air to compress.If this was done at higher speeds very often the sudden change would actually cause the seals to blow out and at very high RPM it sometimes caused damage to the valves (if I had a dollar for every time I have replaced seals...).Based on this knowledge I would say that the blue range is in fact the ideal point for actual exhaust brake use becuase an exhaust brake holds compression so if you where at the higher end of the green RPM range and therefore the engine is producing more compression already at this point use of the exhaust barke could overwhlem the butterfly valve and cause a serious over compression condtion.
