EMP immunity

[MUTNAV]

Yep yep! Or, ideally, you have an air system that doesn’t leak. Air can replace electricity in many cases. I’ve run trucks with air windshield wipers, air horns, air actuators in place of solenoids for PTOs, tire inflation systems, air brakes and suspension, air chucks for tools… cool stuff.

Yep, the (now old) 2 1/2 ton trucks "duece and a halfs" had those, the windshield wipers were fun and needed manual assistance sometimes, although I think they were technically run off of the engine vacuum, with air brakes, the air tanks were recharged when the engine was running. There were actually military training roads that trucks with air brakes were not allowed on because its possible to run out of compressed air if not careful on a long downhill section.

Compressed air is an under-looked at possibility for energy storage without batteries. (A more common possibility is to pump water from the bottom of a hydro-electric dam to the top. The other less considered possibility is using large salt caverns to store compressed air.

On a very small scale a normal person could do it (kind of) by using an air compressor (that runs when more electricity is produced than used) to fill an air tank. When the stored energy is needed, an air drill connected to a small generator would provide some power. (none of this is sterribly practical, but it is an option).

You might survive the event, but unlikely you'd survive any sort of collision in a car like that. Old military vehicle might be your better option.




You could be the first pimp of the post apocalyptic world.

1) A Lada or Fiat 124 will go 4 times further on a gallon than most military vehicles or SUV. You can literally out tun them.

2) If you are going to bug out from NY, do so in style:

..........2-stroke Detroit diesel with an air starter is what you’re after!...................

Cool ~!

It's obvious I know very little about Diesel engines.
I have had the fun, however, of nurse-maid'ing some diesel generators when the temperatures dropped to fifty below (thats were I learned about using kerosene/gasoline/diesel mixtures)- now there's adventure!

I understand how an air-start diesel works-- my question is-- where is the source of the compressed air when everything is in shambles ?
That's a rhetorical question... I figure I won't have much reason to go anywhere if it comes down to that.....



.............but on the other hand, these 'survivalist' seemed to have a transportation purpose--- is that a diesel truck they are driving ?
(I don't think they are worried too much about any radios though)---

As far as the part of the source of compressed air when everything is in shambles, try a bicycle manual air pump . That may sound silly, but even on an F-16 there are two hydraulic accumulators that give the pilot 2 chances to start the engine (initially) in the air they are recharged with engine power.

Usually both accumulators are used to start the engine at the same time, if the engine doesn't start, the accumulators are manually recharged with a hand pump.

The early run of US Coast Guard 44 foot motor life boats had a hydraulic system like that with a hand pump. Problem was, it took something like 400 strokes of the hand pump to get enough pressure to spin up the Diesels. After a few months of that, an electric starter was added.

I loved the 44 foot MLB, they weren't as fast as the new boats, but look like they could survive a hurricane. They LOOK like a coast guard boat.

Great features, low sides for getting people aboard, a separate survivors compartment, roll over survivable (although I read the engine room needs a good cleaning out after-words).

CH-47's (if I understand it right) use the same arrangement of manual pumping if needed.

For the F-16, the effort is said to be like doing a lot of push-ups.

Yeah, but if you are going to bug out from L.A. you have to be a bit more classic:

The two stroke Detroit would run fine, just don't overfill the oil, If you do, it will run like a 454 Chevy with a super charger for a few minutes! As far as modern cars, limp in is not the tranny in second gear. It's just enough to get you of the road at 1500 RPM and not to little throttle response. Comptech, 45 year ASE Certified Master Tech and still chugging along.

 

[KMG54]

Most cars in limp mode will do 55 or 60 but at that gear ratio, you'd eat gas like crazy.

Not true in todays cars, cat damage takes number 1 priority. Believe me, I had a Hyundai Velocitor today that would not get out of it's own way, It was a manual car and took everything it had to get it to move. Direct injection car and the high pressure fuel sensor was bad. It was saying it had 2200 psi of fuel pressure, when everything else said it should have 1300 PSI.

Because it's ridiculously inefficient.

Because it's ridiculously inefficient.

It has to be compared to what it takes to make a modern Li-ion battery, in large enough sizes to store grid energy on an industrial scale, and then replace the battery when it no longer is able to do its job well.

Hyundai does not know how to build a durable GDI engine. You won't see many running 3rd generation Hyundai's during the zombie Apocalypse. The drivers will have become Zombies.

 

[KMG54]

Well known problem with the GDI engines, Most were replced under warranty, but their electronics susk to top it off.

 

[KMG54]

Of Kia is the same of course, same motor same problem. Easly fixed with learning how to read a micrometer.

They must hire the most obtuse ME and EE's in the automotive industry.
I have a second generation 2007 SF (with the good 3.3L engine). The automatic door locks failed. Over $2000 to fix by replacing all the cheesy yet complex and expensive actuators buried inside the doors.

In contrast my 2001 Ford Expedition door locks failed and I fixed myself with no parts, just a big rivet tool from Harbor Freight.

You can read the resultant scoring on the GDI cylinder walls with a ruler!

 

[KMG54]

The problen was they built the motors to tight, they made special oil filters to handle the over pressure. A couple years later they were ordered to replace engines.

Yep they were recalled because they were launching rods and causing fires.

 

[MUTNAV]

To bring it slightly back to EMP (although the engine issue is interesting, I still think my 67 Beetle ( which I don't have any more) would work a lot better ), I think an EMP simulator would help clear up a lot of the theories that are going around, and help producers build better products.

Oh yeah, lets see what 3000lbs of fuel pressure will do to cylinder wall.

It really sad because they were making some good cars for a while.

I agree, I dont think an EMP will do any damage to an old Bosch Blue coil
