Internal EGR? Is this the main culprit here . . . described as carbon slag on intake.
If the Intake valve closing is causing back-flow, depositing particles then a catchcan is useless.
So droplet size and oil fuel chemistry is possibly preventative, as well as engine loading.

Tugboat? Is this a setup?
‘ . . . anybody tell me which fluid or material in a vehicle will autoignite at any temperature under 451°F or 265°F?”
Strangely reminded of a certain famous Italian, to whom credit is given for the invention of the voltaic pile, Alessandro Volta:

Yesterday heard from a neighbor of unusual brake failure on late model hybrid SUV:
Two new vehicles owned by young family, wiring harnesses of both vehicles chewed by rodents,

According to NTSB, 2017 report, the fire risk of EV is comparable to ICE, or slightly less.
Fast-forwarding three years to the above referenced 2020 data, and something changed. But what?
How did EV’s become ten times less fire prone, in just three years?
I must admit these cars are basically...
Ok, electric cars are 11X less likely to spark-up than ICE. But, only in America.
For the rest of this planet things are less rosy, as in China for instance, where the incident rate may be considerably higher, about 11X:

MortenA: Get a grip . . . ICE vehicles catch fire many times more often than EV’s.
Is this only anecdotal evidence due to the preponderance of ICE vehicles?
The ‘flashy’ article linked above by you, claims Hybrids are 3X more likely to burn than their conventional counterparts; in a “now...

Heard this anecdote from an engineer somewhat the reverse scenario:
He was between jobs and so picked up a gig with a remodel contractor through an acquaintance; the contractor agreed to hire him right off, offering a sub position installing a kitchen countertop:

Hey folks, late to the game, am only now reading this news story. Question: is this a hydrogen fire? — besides the headline the footage is of a $1.1 million, fuel cell bus on fire. These are lithium electric buses, with a composite hydrogen tank, but maybe the fire was caused by the lithium...

- Yes, noticed this too. The thing might self destruct unless it’s intended for one way; torpedoes or such. Found this design by Duke engines that uses rotating swashplate but restrained conrod...
May e worth considering the possibility that this crack isn’t tension, but compression failure.
Before modern grading, lumber was visually graded and not mechanically stressed, so brashness from felling the tree could get passed over, resulting in failures like this later down the road.
Hello BrianPetersen. Should regen have brake lamps? Yes. No. Maybe. It’s a firm fifty-fifty.
The car in question above, is motoring down the freeway by itself, unsupervised. In fact the car is supervising the erstwhile driver, that he is semi comatose. In this situation where the car is the...
I think my take, that regen activated brake lamps are potentially dubious, is too simplistic, This can’t be pigeonholed into whimsies of an experienced driver, versus, *somebodies granny is driving that car* arguments(unnecessary braking). Rather, proverbial *nanny-state* is looking to the...
Big rigs don’t apply stoplights with the Jake Brakes, but some RV’s do. The driver should positively control the stoplights, otherwise it can provoke an incident; and while the reverse situation may also be true, an experienced driver will prefer to control vehicle stoplights.
Reading through this thread has given me this idea; what if the forming cylinder for the carbon were a pressure tank, which is then hydro bulge-formed and the carbon fiber is cured in tension. With the metal pressure cylinder supplying sustained outward pressure, the carbon submarine is no...
Wish I could say I knew something practical about this, but am still largely baffled by it. Think I understand shotcrete and prefabs’ but not so much the ribbon of mystery mix cement. It seems to be a variety of adobe, slump wall.
