Depends hugely on the type of "diesel engine". Old ones probably
won't miss a beat, some stationary engines in particular are designed
to run on almost anything.

On the other hand a modern car engine probably won't like it very much.

Also depends on how much and if its mixed with the correct fuel. It will
probably stink I'd imagine as well.

As we know modern diesels being run on old chip shop oil ... messy,
smelly but it works.

Actually, I dont think we do know that. We know that older IDI engines
were much less fussy but modern common rail DI engines dont do well.

Likely it would be fine given that most will run on even vegetable oil etc.

run fairly well

kerosene AVJET and red diesel are very similar. Kerosene is a slightly
lighter mix, and normally doesn't have all the antifreeze additives that
diesel does - road diesel also has some other additives to help engines
stay clean

I know someone who used to un his cars on a 50/50 mix of central heating
oil and road diesel.,

Kerosene may not have antifreeze because it is lighter than diesel. And
historically kerosene was added to diesel to stop it waxing.

Flight at high altitude would be hazardous if kerosene froze!

Hmm, I wonder how close to home?

Does kerosene provide sufficient lubrication for the fuel pump? I
beleive these pumps rely on the fuel for lubrication and can fail if
they're not properly lubricated.

It is certainly often claimed that more modern systems have smaller
clearances in pumps and injectors and that there are lubricity additives
in automotive diesel to give these components longer life.

I've seen a report on a motoring programme (not Top Gear) about what happens
if you put diesel in a petrol car or petrol in a diesel. They demonstrated
on old bangers that it didn't matter if they wrecked. Both sort-of ran,
though I think the petrol car smoked badly on diesel and at one stage
belched sparks out out its exhaust pipe.

I dread to think what damage was done to the cars. The report did say that
they couldn't use a more recent HDI (high-pressure direct injection) diesel
because that would suffer immediate and catastrophic damage to the fuel
pump; an older engine with a lower-pressure mechanical pump was fine (up to
a point).

The funny thing is that one of the cars continued to be taxed and MOTed for
about 5 years afterwards. I wonder if the new owner of it knew of its
history ;-)

I did that to my 2016 S-Max. My first disel, and it was two years before
I accidentally filled it (well, a bit over half full, rest was diesel)
with unleaded. I got about a mile. RAC came and pumped it out, had garage
change the fuel filter.

I fitted a Fuel Angel to stop me doing it again. Great. I thought. A few
months later I managed to defeat the Fuel Angel, but I had parked at home
before I realised. Garage took car away and drained it, etc.

I changed the car very soon after.

I would run fine. Until one of the many high-tolerance components in the high-pressure system wears out or seizes due to the lack of lubricity in the fuel. Or one of the plastic seals in the system swells or shrinks due to the different chemical composition of the fuel. It might take a long time for any of those things to happen if it's a relatively old fuel injection system.

I could find an example here, of advice.

One way or another, a "diesel additive" may make the different
to kerosene as an engine fuel. We have to keep the "mystery"
in this stuff, of course. If we let too many refinery secrets
loose, cats will end up sleeping with dogs.

Our cats already do that. :-)
