I need better fuel economy here, a 4 cyl would help!!

CobraDriver · 09-28-08, 12:59 PM

Ok so I've gotten into the bay, took the pictures of the subs, snuck out and half way home out of gas.

I've gone into the bay, did the recon of merchants, killed a few, haf way home out of gas.

Now it was obvious I wasn't going to make it home because it took more than 50% fuel to get there. I was at 2/3 speed and and standard and making sure that as soon as my batteries were charged I would go to periscope and run off batterythus maximizing my fuel, and it still took a bit over the 50% to get to the objective. Silent running was not an issue cause I don't do that much. I even went as far as coming to a complete stop to recharge my batteries so I wouldn't burn gas and still didn't make it.

Someone have a reason for this?. I keep thinking when you compress time it screws the economy up, and I run alot of compresion to and fro. I keep it around 1000.

Any help would be appreciated.

Oh yea, running 1.5 with no major mods, just green bulbs, the compass rose and clearer torpedo wake.

Where is your home port? And also where was the photo recon mission. On a side note I only run submerged when absolutly necessary, and run at standard bell except when recharging batts at 2/3. I have never run out of diesel except when damage was taken.

Task Force · 09-28-08, 02:11 PM

surfaced you should run at 1/3 speed, Ive gotten over 9,000 in a S boat and over 10,000 in a fleet boat.

-Pv- · 09-28-08, 02:46 PM

I agree with Task Force. You should not be using anything higher than 8-9 knots when on long missions and you're not chasing a target. You should be charging batteries at 1/3 speed so they charge at a fast rate, thus when they are charged, you will get maximum speed. Also, mods which try to lower the sub in the water to reduce the visual effect of wave striding, also reduce the sub's range to less than historical.

Assuming you're in a Gato or a Balao, your most efficient speed on the surface is between 9 and 10 knots. I can go from Midway to the East China Sea, patrol there for two weeks with intercepts along the way and make it back to Midway with plenty of fuel to spare.

CobraDriver · 09-28-08, 04:41 PM

I leave from Pearl, go to Midway, refuel, went to the Tokyo bay, saw the 7 subs, took some pics and was already past 1/2 fuel on the way there.

As far as speed, I have it at 2/3 and standard....neither have done it for me.

So in short I figured out how to kill stuff

I just suck at driving the thing

The diesels are still running to charge the batteries, so this too consumes fuel. I think the only way to consume no fuel is to have a full battery charge and not move--I do this some when loitering on station but it is no good for transiting obviously.

Allowing you to recharge at a complete stop without consuming fuel would amount to a free lunch.

SteamWake · 09-29-08, 08:45 PM

Comming to a complete stop to recharge?!

What is that supposed to accomplish. Your batteries are going to recharge wether or not you making headway.

Seminole · 09-30-08, 06:51 AM

For one thing..you don't burn any fuel while the batteries recharge...and even though it is most unrealisitc to reharge while the diesels are idle .....it is a fact of life in SHIV World...sorta like the stars being closer to earth than the clouds...

Oh..forgot to add...after you are fully recharged you can then resume steaming with recharge batteries "off" which increases fuel range efficiency...enormously.

You could of course simply turn off recharging but some skippers don't feel at ease traveling with batteries not fully charged.

Diopos · 09-30-08, 07:06 AM

OK groomsie, Seminole and SteamWake.
Please put your cards (mods) on the table.
The battery recharging at zero surface speed and an empty diesel tank was a supposed to be an early stock version bug! Am I right? The ability to recharge at zero surface speed with no fuel consumption is still a bug! Groomsie how did you deduce there is no fuel consumption?

@ Seminole & SteamWake,
there are posts which state that during battery recharge all diesel engines work at "maximum". If you're static your batteries charge faster. If you're moving the highre your speed the lower the battery recharge rate!

DID YOU LIE AT ME!

I think I must walk the I-must-experiment-plank!

groomsie · 09-30-08, 07:26 AM

Nope, my point was I thought you always burned fuel on a recharge, irrespective of speed. That would be realistic (after all, the battery is simply storing the energy generated by--you guessed it--the generator, which is turned by (surprise) the diesels).

I understood that recharging at all stop with no fuel consumption was a bug in older SH versions (prior to IV), but I thought it was corrected here. If that bug is still present it is certainly unrealistic and would be nice to have corrected.

Bottom line, it should cost you a certain amount of fuel to place a certain amount of energy into the batteries. Period.

Never claimed such a thing, in fact I stated that in the game it appears that the batteries recharge at a constant rate regardless of 'throttle' settings. If there is a difference it is not enough for me to notice. So sitting still or all ahead flank the batterys charge.

Just keep it at around 9 knots and you will be okay. The thing is you will consume more fuel while recharging at 9 knots than when your not recharging. But... your still doing 9 knots.

This is contrary to 'real life' where what you state would be true.

Maybe I got too "cute" with my wording and made it confusing. If I have a full battery charge (100%) and don't move, no (very little) energy is needed. Anything else should be consuming fuel. So sometimes when on station and waiting I'll sit in one spot rather than just burn fuel (and if the batteries are topped off that should not be consuming fuel). Sorry for any confusion stemming from my post.

Quillan · 09-30-08, 08:37 AM

Even with a fully charged battery set, you still burn fuel sitting still on the surface. It's just not much. Once I'd been sent on a 7 day patrol of the Marshal Islands (where there are no ships, not even friendly). I spent the entire week stationary on the surface, and burned off 2% diesel while doing so.
