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. Getting a clean burn like that sounds very difficult.
