Question about exhaust smoke

I'm trying to modify an engine to have a rolling coal effect under acceleration. The problem is, that the only thing I found that is related to exhaust smoke is this:

Code:

"engineDef":[
            //engineRPM, efficiency, exhaustFactor
            [0,     0.0,    0.0],
            [650,   0.35,   0.4],
            [1000,   0.8,   0.4],
            [1400,  1.1,    0.6],
            [1900,  1.2,    0.8],
            [2500,  0.8,    1.0],
            [3900,  0.7,    1.0],
            [4900,  0.6,    1.0],
            [5200,  0.4,    1.0],
            [6000,  0.3,    1.0],
        ],

I only see a possibility to link the amount of smoke to RPM, but the changelog says engine smoke is based on engine load. What I'm trying to do is to make it NOT smoke when engine braking, or giving it little gas, but smoke like hell when I floor it regardless of RPM. The wiki didn't help, because it only has info about radiator smoke and stuff, not exhaust.
Any help?
Oh, and thanks to @synsol for the Pessima diesel mod and the idea!

 

Code:

"engine":{
        "idleRPM":650,
        "shiftDownRPM":1300,
        "shiftUpRPM":2000,
        "maxRPM":5100,
        "inertia":0.8,
        "friction":14
        "brakingCoefRPS":0.15
        "burnEfficiency":0.51
        "throttleSensitivity":1.2
        "torqueReactionNodes:":["e1l","e2l","e4r"]
        "particulates":0.2

"particulates":0.2
I don't see the possibility to link it to throttle.

 

The "particulates" parameter is what controls smoke, for my t series mod I increased it to around 1.8.

Code:

   ],
    },
    "engine":{
        "idleRPM":500,
        "shiftDownRPM":1300,
        "shiftUpRPM":2500,
        "maxRPM":3000,
        "revLimiterRPMDrop":0,
        "inertia":12,
        "friction":100
        "brakingCoefRPS":5
        "burnEfficiency":0.22
        "throttleSensitivity":1.3
        "torqueReactionNodes:":["en1l","en2l","en4r"]
        "particulates":1.8

 

That's not the problem. It smokes when engine braking. It smokes when I'm not giving it gas. I want it to only smoke when I floor it.

 

Agreed.. I would love to have an in depth explanation on exhaust smoke.
I've been trying to find where it links to throttle or engine load as the devs said, but it seems I'd have to edit a core lua game file.

If anything, especially on diesel engines, exhaust smoke should be linked to turbos and throttle. The T-Series for example: When you punch it in the T-Series it seems you get the same amount of smoke particulates throughout the whole RPM range. In a real semi, you're gonna see a puff of smoke as you give it throttle, but as the turbo spools and boost is built up forcing air into the engine, no smoke.

 

Yup excatly, hopefully the devs will fix this.

look at my thread linked below for my thought, on a "dynamic" smoke system.

Is there any updates? I found a cumming MOD and would like to up the smoke factor

 

How do you get to those settings? To change the smoke?
