rather than downshift when zero throttle is insufficient, it can then selectively apply reverse thrust or throttle (for lack of a better word) with the exhaust brake rather than downshift like a gas engine.
You're going to have to explain that one.
Maybe, "it can then apply variable amounts of reverse thrust or throttle . . . " might be a better way to phrase it, IDK. If that doesn't help, maybe someone else can chime in with a better explanation, sorry.
It sounds to me like you're saying the engine can inject a small amount of fuel long enough before the piston's TDC that it ignites and burns while the piston is still on the way up in the compression stroke. I was not aware any manufacturers had programmed that into their engines.
Sounds to me you may have a better "technical" (behind the scenes) understanding of how a diesel exhaust brake operates than I do. That's fine. My explanation was my best attempt to explain it from a "seat-of-the-pants" perspective to someone why may have never used one before. To me, it feels very similar to reverse thrusters being activated on an aircraft--no more, no less. Hopefully you did notice I qualified my explanation with "
for lack of a better word". You're more than welcome to describe how it feels to you, or explain how this sensation is achieved from a technical perspective. I'm all ears--lol!
