High Altitude Engine Bug

When you shutdown the engine at very high elevation, its friction becomes INFINITY.



Note the powertrain app and the Altitude(Elevation)

Watch video(see attachment)

 

Well looks like I misinterpreted, the problem is after shutting down the engine, both the starter and dumping the clutch are unable to start it.

BTW, is there any console commands to delibrately set engine RPM, such as setting the engine RPM 1000 instantly.

 

Huh, I found the culprit: when the engine idle torque is lower than engine friction, the physics calculation codes will intentionally break the engine regardless of what caused it, even without engine damage. Either with a (mod) bad starter, or with restarting engine at very high altitudes. The engine then won't turn even you teleport the vehicle to sea level, use tremendous force to push it(shift to 1st, downhill in Jupiter gravity, nodegrabber etc.).
in "BeamNG.drive\lua\vehicle\powertrain\combustionEngine.lua" line 560~564

Code:

  if device.frictionTorque > device.maxTorque or (device.outputAV1 < device.idleAV * 0.5 and device.frictionTorque > idleTorque * 0.95) then
    --if our friction is higher than the biggest torque we can output, the engine WILL lock up automatically
    --however, we need to communicate that with other subsystems to prevent issues, so in this case we ADDITIONALLY lock it up manually
    device:lockUp()
  end

I'm sorry, but the logic behind this is beyond my comprehension.

 

That seems understandable, I guess I should stop splitting hairs then.

 

Another thing is that engine braking is caused by the vacuum or air resistance of the throttle valve, thus the "enginebrakingtorque" should reduce according to elevation. However, currently in BeamNG it does not do that, making engine braking torque at high altitude as much torque as at sea level.
