We've got an old IH 856 with a 90ish horse six cylinder naturally aspirated diesel in it. Old gal leaks every possible fluid it's supposed to have in it. But it'll fire right off no matter how hot or cold or how long she's set. Loud as hell with one of the above mentioned hollow "mufflers" on her that's been ripped off and reinstalled after some straightening numerous times when plowing under the tree line. But I swear that old timer wasn't lying when he told me "that 856 is a good tractor, it'll pull a JD4020 in half". Good old rig that mostly just gets used for stacking hay these days.
Aspiration refers to air flow, not fuel. A naturally aspirated engine can be carburated or injected. It just means that there is no forced air induction.

To me, the term means, no turbocharger, or supercharger. Beyond that, ??
Naturally aspirated means all of the above plus injectors, NA means carburetor.
well John Deere called all non tubro motors natural aspirated at least up to the 55' series
Yup, and technically straight injection/injectors are natural too, but, old school me has always thought natural aspiration meant Holley or Mikuni's and usually a big fuggin hammer.

This.
Aspiration is how the air gets in. Nothing to do with how the fuel is mixed into it (carbs or injection).

This has been the case since the term was first used (at least in our town) many years ago. AND, it not only meant zero forced air induction, it also applied to some exhaust factors. We could mildly port and relieve manifolds/tube fixtures and even use headers without getting called out - but scavenging was considered not natural aspiration back then. Related - I was somewhat amazed after taking four carbs off my Corvair coupe and mounting the turbo setup from a Monza Spyder - complete with one bIg Solex - back in 1969. That horizontal six banger woke up furiously - a sleeper/killer around Tucson. NOT normally aspirated - and had a hard time keeping the seal working - heat issues. Loved that rig - could not wear that engine out. Later had an 89 Ford T'bird Supercoupe - big time supercharger boost with 5 speed manual - a genuine flyer and great roadwork suspension. Had to run "Z" rate tires on that one. I examine these mechanical marvel turboed/injected/computer controlled engines today and can't begin to figure out what is normal. Content to just be old-school - still trying to learn the fine points of diesel.

Its a good feeling when you set the rack on one and all the little U's on the individual injectors pop up at the same time.
It is a bad feeling when you set the buffer spring wrong and the damn thing runs away. Even worse feeling when the knob from the kill cable comes off in your hand.
Worse still when you have to use the boss's new phone book on the turbo to get it to stop.
Good feeling when the seals dont pull out of the turbo and bring the engine back to life.
