Diesel smoke modeling Are there any laws (have to be)?

But the behavior of *.eng-file settings is still unclear for me, and even long-time experiments not always bring the desired result (more correctly-it was never achived completely).
I have read about interferention of settings from the original (MSTS diesel smoke effect) and include (OpenRails diesel engine block) *.eng-files for diesel-smoke definition.
As well, massive smoke emission sauces my notebook to freeze.
This way, I see the continuation of this theme at "adding to Manual" and "graphic issues" topics, but all questions need to be formulated first.
I want to know, does someone learn how it works, or maybe the programmer will explain to me, how exactly was this mechanism implemented.
It's interesting too, did someone interest in this question and did someone achieve desired results, makind the diesel smoke appearance more close to prototype?

Hello, i also had the same problem (excess smoke that freezes the pc), so i entered into the .eng of the engine and modify this:
DieselSmokeEffectInitialMagnitude( 1 )
DieselSmokeEffectMaxMagnitude( 2.5 )
DieselSmokeEffectInitialSmokeRate( 1 )
DieselSmokeEffectMaxSmokeRate( 3 )
I decreased the values, doing that, the smoke will decrease and the performance will improve, also givin a more realistic aspect, that is what i can see, after the changes.

2-stroke, 4 stroke, having supressor or no, how many cylinders and crankshaft's speed, condition (old/new)

is thar the "pressure" of the exhaust gases is growing-up excessively alongwith smoke quantity, wich causes the increase of jet height, but IRL the pressure even drops slightly that time because unefficient fuel combustion.
So the question: is it possible to control the height separately, or wich parameter refers the height and how it does that?
The engine on image dOes have an acoustic supressor, so the pulsation of a jet is smoothed, but many engines have no that device and the jet could be high...

Is it possible to change and does it have sence, relative to other world diesels?

Diesel smoke is dirty gray (not black, greasy). As the rotation speed increases - it darkens and thickens. As the speed of rotation decreases - it is brighter.

I use texture by 3D trains, but it's white
Do you mean, THAT's a problem?

1. I define a diesel engine using the ORTSDieselEngines block
2. I do not use DieselSmokeEffectxxxxxxxx parameters. This is a remnant of MSTS and OR has better options to set up the engine.
The locomotive in the video has smoke set as follows:
Comment ( "Agregat" )
ORTSDieselEngines ( 2
Diesel (
IdleRPM ( 650 )
MaxRPM ( 1400 )
StartingRPM ( 435 )
StartingConfirmRPM ( 715 )
ChangeUpRPMpS ( 100 )
ChangeDownRPMpS ( 75 )
RateOfChangeUpRPMpSS ( 10 )
RateOfChangeDownRPMpSS ( 10 )
MaximalPower ( 478kW )
IdleExhaust ( 4 )
MaxExhaust ( 11 )
ExhaustDynamics ( 1.2 )
ExhaustDynamicsDown ( 0.5 )
ExhaustColor ( 00999792 )
ExhaustTransientColor ( FF5B5851 )
DieselPowerTab (
0 0
650 0
740 100380
840 176860
930 237805
1120 347745
1210 395545
...
and to ../GLOBAL/TEXTURES/dieselsmoke.ace

(After all, the same problem is being solved here)

So You do not suggest to use MSTS and ORTS settings simultaneously?
it's likely, that groups of settings are interfere
I use this at the moment:
DieselSmokeEffectInitialMagnitude( 0.8 ) DieselSmokeEffectMaxMagnitude( 2.9 ) DieselSmokeEffectInitialSmokeRate( 1 ) DieselSmokeEffectMaxSmokeRate( 3 ) Comment ( ) ORTSDieselEngines ( 1 Diesel ( IdleRPM ( 350 ) MaxRPM ( 1000 ) StartingRPM ( 200 ) StartingConfirmRPM ( 470 ) ChangeUpRPMpS ( 50 ) ChangeDownRPMpS ( 30 ) RateOfChangeUpRPMpSS ( 5 ) RateOfChangeDownRPMpSS ( 5 ) MaximalPower ( 4000hp ) IdleExhaust ( 0.6 ) MaxExhaust ( 6 ) ExhaustDynamics ( 2.6 ) ExhaustDynamicsDown ( 1.1 ) Comment( ExhaustTransientColorDown ( 00808080 ) ExhaustColor ( 00202530 ) ) ExhaustColor ( 008899aa ) ExhaustTransientColor ( ff000000 )

The ORTSDieselEngines block is well described in the OR manual (chapter 8.2)
One small hook (actually two): Detailed motor parameters are required and there may be a problem with the MSTS activity editor (many activity creators still prefer it ...)
