Can there be a way to prefer electric compressor instead of diesel compressor after hydrophone check?

Diesel wastes diesel. With electric compressor after hydrophone check, it will recharge when you surface anyway.

I’m not sure exactly the procedure at the time, but personally I would use the diesel compressor in the game as it refills the compressor in 3:30 minutes as opposed to the electric which takes 8:00

The advantage of being able to dive quicker vastly outweighs the slight fuel cost. I turn them both on to shave 30seconds off the time

There is another element to this, if you go to 6500x time compression right after hydrophone check, it will actually take alot longer in game time to fill up the compressed air, thus resulting in alot of diesel wastage. since you can basically have it running for 2 in game hours or more, but if you play on 1x timescale it weill bascially only use 2 minutes or 3 to replenish the compressed air.

Despite being smaller, the Junkers outperformed the Krupp compressor by about 40%.
I think they'd just run both at the same time to recover the used up high pressure air as fast as they could. If both were working, of course.

tbqh that sounds like a bug

It is a bug, i have submitted a report about it using f11 so they know.

I can also back this up because i've tested using electric compressor on 6500x and it drained 40% of the battery or something like that as opposed to to 2-3% when using 48x timescale.
(filling up from empty compressed air reserves)

So this obviously means the same thing happens with the diesel compressor and diesel fuel, but it is not easy to notice as it is a very small % of diesel.

But if you patrol a very remote area and use hydrophone checks and immediately hit 6500x many times, it adds up to alot of lost diesel and that might cause the course of the game to be changed. (not being able to drive home when you should have enough fuel)

Thanks for the info

You know what else wastes diesel? Recharging the battery charge you wasted using the electric compressor.

The electric compressor is essentially only useful for building enough air pressure in the empty tanks to start the diesel compressor - which needed compressed air for starting - this isn't simulated in the game.

@nihilcat - an interesting consideration would be removing functionality from the electric compressor - players shouldn't be encouraged to use it; players should start the diesel compressor, the electric should kick on for a minute automatically, the diesel compressor should start and the electric should turn off automatically.

ie. remove the ability to use/turn on/turn off the electric compressor at all - simply trigger the "animation" and function of the electric compressor for a short period of time when the player activates the diesel compressor.

That should *only* apply when the compressed air tanks are completely empty - otherwise, if there was pressure in any of the tanks the diesel compressor likely would've had enough air to kick over on its own.

Aside from any of that, we shouldn't even be using *all* the compressed air in the boat to blow the ballast - only enough should be used to surface the boat, the remaining water should be blown out using the diesel engine exhaust.

Instead of encouraging the player to exploit the free electricity by adding functions to make it even easier to use that exploit, they should close that gap.
Charging the batteries should also cost diesel

I guess it's time to fix this... 😉

The diesel compressor had more power, plus it was favored over using the electric one as battery power was precious. if you're compressing air, then an enemy plane swoops down out of nowhere, you'll want to dive really quick, and that electricity you used to refill the air tanks may have just cost you your life.

On the surface, after you just came up, you're probably charging the batteries while charging HP air. The compressor is running off the generator.

You can also run the compressor for 36 hours straight from a fully charged battery. You're being overly dramatic.

Few people know that the compressor needed compressed air to start.
It didn't need more than 30 kg/cm² though, which was taken from the GW Diesel engine starting flasks. So even after spending most of the supply from the HP flasks after multiple successive crash diving and surfacing, you could start the compressor.
The way it works in UBOAT is fine.

at least it would stop me abusing the hell out of it, never needing a fuel resupply because i sail my uboat like a toyota prius and just alternate power>diesel>power>diesel for extra range XD
