put it this way, i worked on a CT50 copy china made engine, tinkered with the electrics, and yes, gasoline engines require a spark, diesel no... but there was ZERO digital logic circuits on that bike, and this was circa 2008, everything was old school 6V analog, hard switches, solenoids, etc. seriously, those who understand, will get it when i say that diesel engines will come back in a big way for utility transport when there is too much frequency of CMEs and the gagnetic shield of the earth goes through its' flip it's going to be so bad that even electrical devices underground will still need some tin foil to stop the gamma from toasting the ICs
For light duty, yes, computers started to hit the road in 1994 models with fully controlled the engines. For Ford this was called EEC-V Diesel Powertrain Control (DPC) V1. These controlled the Navistar (international) 7.3L engine. This era was my specialty. Ford started testing and writing firmware dating back to 1980 but it didn't hit the road till 94. Chrysler followed in 95 for common rail Cummins engines, GM followed in 2002. Volkswagon ran mechanically injected to 2004 iirc for passenger cars here in the US.
Some of the fondest memories of my mispent youth in Australia are hooning around Brisbane in my mate's diesel Golf. We nearly killed it once by taking it bush bashing around Lennox Heads, cracked the oil pan open like a coconut. The local shop got it back on the road in a couple of days and the Golf lived to die another day
Economically were already there with light duty trucks. For the cost of newer used trucks, it would be cheaper to completely frame-off restore a 2000s diesel truck, build an engine block and transmission, update interior and paint for less money. I'm thinking of just paying someone to fully restore my truck instead of a newer one. I can't afford to maintain a newer one either.
Well, yeah, but so is everything else. And hardly anyone would own a car, if we hadn't made them all electric. Making the motor fully-electric is just the last step. Now, cars are really cheap to build, have lower PPMs and emissions, and are more reliable. And the acceleration is amazing. The main problem left, is the weight. Old cars stink like a diesel locomotive, guzzle gas, and are expensive to maintain.
i'll be on foot and bicycle while y'alls have fun with your no radio, no electrical systems working in 11 years from now... i'm almost certain it's going to be doomsday for electro/radio devices, and it will get steadily worse leading up to that, to the point that even if they made a skynet the robots would be fried
btw... you don't need electricity to run an old school diesel engine and it's probably cost effective to turn a shit-ton of rape seed oil into diesel with a bunch of potassium hydroxide you made out of wood ashes, or, i mean, for now easy enough to buy drums of KOH anyway so, yeah, i guess a lot of people are not gonna be ready for that auroras in the subtropics are a warning
It would have to be a very old engine. I was working on diesel powertrain, in the 90s, after all. People dump rape seed oil into their diesel cars, sometimes, but I don't recommend it. And you'd need a heck of a lot of oil, for those old diesels. Probably better off with a steam locomotive burning coal, really. Anyone with wood can produce coal, and we live in a big forest.
indeed... i expect suddenly people are gonna see a reason why depending on electricity right now has been a bit of a mistake btw, having the problem of the sun nuking electrical devices on a regular basis for a while doesn't mean no computers it just means that you have to stick to underground and optical network systems, and drone warfare will be ded, because once it happens a few times there will be nobody able to make them for several years or longer, and i hate to think of the chaos that will break out in large electricity dependent high density city areas... the smart people already are going to villages like your locality
i am definitely going to make sure i have myself a couple of old diesel trucks at some point, probably a 80s era lada niva and whatever is easiest to find near me, get them both overhauled fully and configured to have a full no-electrical operation capability... i expect that suddenly they are going to be worth a lot of money sometime in the next 10 years, and i intend to keep mine in pristine working condition and not work them that hard, either, so they are always available i'm expecting a decade or three to pass with a shattered economy with severe problems with energy availability, and am planning accordingly dreaming about my little library of essential knowledge, and other things to occupy my time in the absence of internet when this happens
On passenger the road #2 diesel vehicles usually saw high 30s to low 50s in MPG through the early 2000s. They did great on fuel economy. Even light-mid duty diesel engines are "good" on fuel economy. We can currently store more energy in a 40 gallons tank of diesel fuel than any battery technology for the same volume. You'd have to include the volume used by the rest of the powertrain, which is fair, to be equivalent.
this kind of meaty fax is why i follow you i was pretty sure that most diesel engines were 100% non-electrical and the electrical things have only been added since the mid 90s to do stuff like improve its cold start and such when i was a kid, it was normal that a diesel engine would not be stopped if it was going to go again within 20 minutes or so, because restarting the engine did damage (mostly adding tar and shit to everything) and wasted fuel... not sure exact details of why, stuff about how the fuel needs to be hot, and every last bit of cold metal the vacuum-vaporised (by the high compression ratio of the cylinders) that was not at working temperature would result in poor combustion and promote tar formation etc etc the original ICE was diesel, and it was hard to do gasoline without adding electricity, and that means, and still means a bulky battery, and there is still really no more robust battery for starter motors even today, than acid/sulfate lithium batteries are a joke, they barely work until they are over 27`C and from about 35`C onwards they start emitting hydrogen, which only happens with a lead acid battery when it's really fucking hot i understand chemistry and physics and that's how i know that diesel engines, even the fancy ones in most modern european cars now, can be modified to run without one single electron of electricity, just that doing so may be more tricky with some than others, just like it used to be a nightmare to work on a Subaru with their weird engine layout
. They stopped producing mechanically injected DT engines in 95. But I know chassis manufactures still used them for a while after, I've seen them :P. So its probably pretty rare to find one in a later chassis, but they were built to order for a while and had lagging emissions standards compared to light duty. A healthy Cummins 4B/T, 6B/T engines and even the DT360s generally weren't equipped with heating systems unless they were in for on-road applications. The major issue with the cold is #2 will gel up and requires mixing with #1 (kerosene) and can usually start up fine under 0*f. Starting aids were mostly added for emissions arguably. Many engines need starting aids, like International V8s, and later 4 stroke Detroits. As the engines wear though, they lose compression and injectors under-perfom and starting aids are helpful and can be required after a certain point under freezing.
