    So i had this idea while messing with the T Series, why not have a runaway feature.

    A runaway is caused when the engine seeks extra fuel from an unintended source. Causing it to over-speed at higher rpm until a mechanical failure, or bearing seizures. Thank you Wikipedia.

    There are only a couple ways to stop this without breaking your engine even more. One is to cover the intake, radiator turbo. Put it in the highest gear apply all the brakes and dump the clutch, and us the handy C02 fire extinguisher. Since i don't know anymore i should continue.

    If you still don't understand what a runaway is here is a video of a guy constantly saying its gone.


    I feel this could great;y contribute to the realism of beamng since the t series (stock with no mods) has somewhat little functional feature (the only fun thing stock is the cargo box.) and add a little challenge in free-roam and the future career mode.

    If you don't care or think its badly. don't rudely say it or waste my time by saying something mean. Give a good reason why not.

    I like the idea. Can you put what causes it? 'Cause that would be scary if i was trying to grenade the T and then it suddenly decided to go fast.

    Diesel runaway generally happens with mechanical fuel pumps, a seal fails and more fuel gets into the intake making it rev harder which increases the fuel pressure and makes the leak worse. The reason it's a big issue for diesels is with compression ignition the only way to stop them is cut the fuel, cut the air or load it to stalling point.
    As the only one of these built into the vehicle is a fuel cutoff it can be quite hard to stop.

    As for implementing it in BeamNG I have to say no, it's a rare mechanical failure and if you start adding them you quickly end up with much longer development times and much higher CPU loads. This is something best left to the modding community.

    I doubt it would affect the cpu much.

    Yeah, i think it would be pretty simple, since the t-series would be old and pretty unreliable(?), the original fuel seals from the 1970's could break quite often. It might be as simple as making it so that if it's being worked really hard pick a number between 1 and 5000 and if it's, say, 7 act like it's permanently at full throttle and start spewing smoke

    All cars no matter how old spawn as brand new. Then how would the burnside drive properly.

    I think it's more like they're not new, they're like new (otherwise the burnside would have yellow headlights instead of white ones) and a semi-truck is much more likely to be a work vehicle: ergo, less maintenance time

    They're incandescent bulbs, new or old they emit warm yellow light.

    It's just until the 80's(?) there was a law in the us that headlights HAD to be yellow

    It isn't an argument, it's just discussion. It's still largely topical, and we're not taking away from your idea. Heck, we're bumping this thread anyway.

    runaways happen when the turbo blows a seal, it runs off the oil that goes thru the turbo then into the engine. Turning the key off only shuts the fuel off, not the oil from the turbo. then when it runs out of oil from running on it, it seizes.

    Old mechanically injected diesels can run away when the injector rack gets stuck at wide open (they start in the wide open position, making runaways much more likely if the motor sits for a while). Not very likely when the rig is new, but it's a real possibility with those old motors.

    except the oil via turbo isnt enough to sustain revs without fuel, fuel shutoff will cause that to shutoff quite quickly. Plus turbo boost pressures actually tend to cause aeration of the oil system which will rapidly increase the rate it will starve of oil.

    but the engine is already running hot enough to burn the oil

    But oil isn't really a highly flammable liquid. But idk.
