Function of the NW-adjuster on the 2l TSI?

Hello,

I am trying to understand, step by step, how the 2.0L TSI (CDL) engine works compared to the classic, simple 4-stroke engine.

For example, the TSI also has an adjustable intake bore. The valve is likely a flat cylinder on the exhaust-NW chain wheel.
But how does this thing work, and how does the MSG initiate the rule intervention?

I can't find a catchy answer

Done: Google search for "Wing cell adjuster".

Yeah

That was also a "popular feature" on the W8.
