diesel sounds or smoke? or just smell?
new torbo diesels do not smoke now, that ended long ago. TDI. born, mechanical inject pumps gone.
so is this a sound or just smoke or some smell. IDK.
long ago diesel fuel sold in USA removed all Sulfur from the fuel making zero smell.. just some tiny NOX, no CO, and lots of CO, same CO humans expel.
modern Diesel have NOX scrubbers, (like the ones VW failed to do right or lied sure)
it is best not to even conflict gas with diesel. (
yes a gas engine can ping, have friend down in Argentina with his old head now milled 4 times, and pings like a pig, so we retard spark huge.
all heads imported there are stolen in customs, or before. (truckers)
the cure is 4 head gaskets, if you can imagine that folly.
if the sound is there, that very very bad pinging. never run a car gas that pings. ever or boom damaged huge soon.
pinging should never happen at cold or hot idle, cold is too rich rich kills dead ping.
it happens under load, for sure of 5sp and logging 4th gear up a hill, failing to down shift correctly and bingo it pings. (if EGR if dead only) (no wild head mills)
most folks now do not even know what ping is nor ever heard it, that is because (not yours) new cars have dynamic ping sensors in the head, that lets the ECU even stop a ping even in 1 cyclinder using wild and magic like , dynamic spark retardation strategies.
back in my days with old CARB engines we tuned the spark by hand (fly weights) and advance to just be shy of the ping point under full engine load driving
that is correct, tune drive tune repeat.
so we know what ping is and all ways to end it. do.
scotty is king of videos. talks fast but topic is complex. so... fast , learn to slow videos down.

this guy could be my brother, he has my same brain. we trust nothing and prove other wise
watch this video on noise, see that large screw driver, ? he uses, then watch the mechanic in DAS BOOT movie do the same thing, NOTHING NEW here back to 1920's , my GF was a mechanic in 1940s to 60s. he died in a gas fire in garage pit from smoker.(+gasoline)
knocking+ping+detonation all are same ,but not same words.
basic noise is not ping, we learn to know that difference, or bark wrong trees.
ping is when gasoline does not simply burn, it is when it detonates. (never good)
one more last name for dieseling, sound, is when you turn he ignition key off engine keeps running.
this is seen on CARB cars. no spark but runs still. keyed off, this is due to a great running engine but the carb key off cut fuel solenoid is bad. stuck open.
A carb and mech pump sends fuel any time engine is pumping air. so can keep running, with no spark, KINDA like and old diesel can, all mech. injected.
