Armored Vehicle Engine Warm-Up Time

[Steeps]

After reading the discussions about turning engines on armored vehicles completely off, I came up with an idea about modifying start up times for armor.

A system similar to how aircraft have a warm up time to begin flight could be implemented as a realism factor to how armor crews give the engines time to warm up before they can move a couple dozen ton vehicle. This warm up time could be different for modern and non- modern tanks to simulate the computer systems onboard modern tanks.

Sounds atleast good to me, it would be also less effort to implement.

Let's see what the others think.

[ExeTick]

I think this is good. I dont see any harm doing this. and I actually like it

5-10 seconds for diesel eating machines and maybe 10-15 seconds for Abraham tanks?

[godfather_596]

Don't gas turbines take about 1 min to warm up? Other than this balance issue I think the idea is great. It also sounds easy to implement.

as for implementing, think its been tried via python before with bad side affects but dunno for sure and possibly other ways of doing it.

I think this video shows pretty good how fast a m1 abrams need to warm up before driving. probably plenty more out there

he start the engine at 0.32 and I think he can drive it at 0.57 seconds. I think this engine was still warm so it might be different from a cold start.

Damn... Sounds like a jet engine spooling up

I think it would be a great addition to the game Just like the choppers need to wait 30 seconds before taking off, why not the MBTs ?

Also, you could add the "You can't operate this position alone" with the black screen to the gunner when the driver jumps out

I personally hate getting out of my tank, and my gunner always urge me to do so so we can hear other tanks, but I've never find this tactic realistic...

Rhino, those side effects were due to the col meshes being wrong, or not having dummy wheels. Anything that can be tracked should have those correct, or tracking will cause problems too (See the British armor)...

But yea, we would need to fix all of the col meshes/dummy wheels, and I personally have no idea how to do such a thing...

It is a "jet engine" spooling up. (Sort of)

The engine is the Lycoming/Honeywell AGT1500 series, a gas turbine that is in many ways similar to aircraft models. While it is easy to start up, it's best to make sure things have "settled" before stomping the gas pedal.

And in that video clip, I couldn't tell how recently they ran the vehicle's engines, but from what I could see, getting it out of there before it became further bogged was more important than "being safe" with spool up. It's better to fry the engine or transmission and get it out of the funk, than have some poor ******* with his wrecker come out and spend the day pulling it free and lose much of the vehicle to water/mud damage.

That and they appear to be in the middle of some kind of combat training course, MILES and all. The loss of one engine due to abuse is worth not having multiple vehicles stuck and at risk. And soldiers have drowned before or been killed/seriously injured for not taking it seriously.

cold start warm start is basically irrelevant, as the only reason this would be implemented is to fight the constant sound check/hill peak tactics, where the engine would only be off for 1 minute or so, after driving, and then restarting it.

A "warm start" would be the thing we would be trying to simulate.

My opninion on this as a armour crewman; i think warm up time is not realistic. My vehicle (CV90) can drive right away when started. Just like our Leopard 1 ARV... Even after standing stationary after a cold night with snow...

As also, i think diesel powerd armourd vehicles are designed to drive away right after start. Think of wartime scenarios; Tank is in a conceald location, engines of because of the sound. It takes fire and needs a quick getaway. Then it will really suck if uou had to wait 10 sec before you can drive of to safety. And 10 sec is a long time in a tank fight...

Just my 2 cents from a proffesional point of view.

But you can drive straight away? there is no warm up time for drivers, only for gunners.

[DieVoorJe91]

Yep. You start here up. Put her in gear and there you go. Gunners do have startup because they need to boot the gunner systems. This takes some time.

This not only pure genius to counter the (possible) bad side effects of turned off engines, I actually considered it to be the 2nd half of that suggestion right from the start.

It is so logical that I just assumed it was already suggested or tried out.
"If a tanker wants to use the advantge of a shut down engine (no sounds) he also has to take the disadvantage (not driving off immediately)!"

Anyway Sounds perfect to me!
In fact I would also suggest this for ALL vehicles across the board!!!
With shorter warm up times, sure. But it is and keeps being super stupid how you can jump in a car and directly rush off.
A 1 or 2 second warm up time could be given imo.

[Pvt.LHeureux]

WAIT WAIT, if what DieVoorJe91 is true, then maybe the start up time could simulate the driver getting into the driver seat, instead of teleporting to it like in PR/bf2 right now?

[Moszeusz6Pl]

It's sounds like good idea. There is no way, that somebody could jump in vehicles and manage to turn it on and start driving so fast.

[Ninja2dan]

The above is directly from the M109A6 operator's manual, regarding engine startup procedures. Note that although it states to let the engine idle for about 2 minutes, the actual time will be determined by how quickly your gauges show that all levels are within their proper ranges.

I'm also looking at the TM for the M939 series (5-ton), to confirm what I remembered as approx startup times. In temps above 32F/0C, the engine should be allowed 5 minutes to warm up. In temps below 32F/0C, engine should be allowed 10 minutes to warm up. But again, these times are rough estimates, but the priority is to check gauges and monitor system levels.

If your vehicle has been running recently, where pressure and temp levels have not dropped back down to "cold" conditions, then startup times will be shorter. If you haven't done proper PMCS lately, or have been operating the vehicles in harsh conditions, startup times might be longer.


In combat operations, soldiers might not care about risk of engine damage and attempt to operate their vehicles without following the proper procedures. That bold text marked all over the TM's and FM's was ignored during their training, or some half-wit NCO told them it didn't matter. And in many cases, it's true, you can rapid start engines and not sustain any damage to the systems (visibly). But the fact is that failure to follow proper procedure does cause wear and eventual damage to the components, and may lead to system failure at the worst possible time.

Sometimes, risking the destruction of your engine or other components is worth it, if it saves the lives of the crew. But under non-emergency conditions like that, most vehicles should never just be fired up and thrown into gear.

People here basically suggest a warm up time for the driver. The time it takes to climb in your seat, put in the gear, power on the engine etc...takes at least 10 seconds i guess....and i actually like this idea. As said above this should be done with every groundvehicle. If you need 5 seconds to man a 50. on techie you should also need at least 5 seconds to drive off after you jumped into the car....especially in stressfull situations...like being fired on and you run to your car jump in and drive off immediately. You will most likely drop your keys or something just like always in the movies

[Spush]

It's on our to do list I believe, we've tried it out before but there was some issues which will have to be solved before this gets implemented. Probably won't happen in 1.0.

[DieVoorJe91]

This idea is better then the original one IMO.

The idea to first idle the engine till its warm is a bit far fetcht. I know nobody how does this. Sure it is better for the engine.
