At least we got an official name for the Abrams engine and there are also a lot of pictures and specs out there about the engine, with charts and schematics. Cannot say the same about modern Chinese tank engines, AFAIK. Not even about the engines on the export models.
The wiki articles on Chinese engines do often not link to sources stating specs about the engines or outright link to pages not talking about the engines at all. We have very little info about them.
And please do not false equivocate engines with other parts.
Yes that's basically exactly what I've written. The available information ranges from having names and some photos and basic specs to knowing nothing outside of the thing exists. Like the Type 99A engine for example. We know from "leaks" and rumours that it's probably running a 1500hp engine that derives from a family of engines based on MTU technology. That's all. So in reply to your original question, it's a stupid one. There is no false equivocation because you misunderstood what my point was.
I'll say it again in more direct terms. China does things differently to the US who does things differently to India. No one is more right or wrong. They just choose their way. China doesn't give any details at all. US gives some details in some places. India gives details before they even develop a prototype. None are more right or wrong they are just different in their approach.
So kudos for getting a name for Abrams engine for your personal database or whatever your aim is. We don't know anything about Chinese engines and that's the way the Chinese prefer for a multitude of reasons. The main reason? Because they don't need to provide you or anyone with those details. Why waste time publishing and showing off details when it serves them zero benefit and will only work against them?
Strategic revelations of details are done to make a subtle statement or show capability in a warning. For example, if the US were to entertain the idea of initial nuclear strike on China, it pays to show the Americans that China can respond. This avoids a mutually costly accidental engagement. Similar with hypersonic weapons (well the Americans already knew for about a decade since they've been observing Chinese tests). Same with the AShBM that some hawks doubted could hit sea targets let alone moving targets. Guess what it did both just to show the capability existed and was ready decade ago when they said they were ready. This hopefully prevents adventurism.
Other revelations are done because they either just can't be avoided or they are of minute strategic importance. Sometimes they are done to rile up nationalism but that's very rare often a by-product. I mean you can't exactly hide a carrier being constructed.
