Renault V6 Power Unit

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Is renault engine going soon to be the last engine in the f1 grid performance wise?

Sorry I am not sure about "cassoncino di aspirazione" translation, it could be inlet air case (or maybe air intake system)
Some sort of rotary feature inline with the intake runners. (yellow circles) Throttle plates? Some say these aren't used in the current formula.

Also, I found the source of Renault's compressor inefficiency (green arrows).

Would they not be mount holes? or are you just being ironic?

Those holes are for tools to pass through probably.
They are also present on the mercedes air box. Maybe for vilm adjustment.
For Sure!!

I reckon the throttle plates are metal and bolted onto the head similar to the V8 engines.

It's a joke, that the turbo'd air is escaping out the holes!

It's a pivot, either for the throttle bodies or for the VLIM system - you can see the rose-jointed control linkages further back.

Hydraulic VLIM?

Doubt it, would guess electro-mechanical actuators.

Lower holes are the shafts for the throttle blades, and the upper holes are just access for the flange bolts in that area. they are not open to the inside of the plenum.

Electrically controlled, hydraulic operated, much faster than only solenoid driven. The weight penalty is almost negligible and the benefits of faster VLIM control I think would be worth it. But eh, not my pumpy lump.

Surprised no one talks about the shape of the ports.

what's solenoidal action got to do with it ?

I thought eg the (NA) throttle actuation was based on electric motor action
rotational or linear
proportional and precise

Modern electric actuators can have quicker reaction times and be more precise than hydraulic ones.

Aircraft are moving away from hydraulic actuation to electric for this very reason. (As well as reliability).

The cons are more expensive and still generally not providing as a force, neither of which is a factor in this application in F1.

Also as TC said, they don't need to be solenoidal action isn't the only way.
