MitsuStyle - View Single Post - New turbo technologies: split turbo and 3D printed variable turbo

BriK · 07-10-2014

I was talking to a couple people about this at C&C this past Saturday so I thought I'd post some more info on it.

For those that don't follow Formula 1, new rules for 2014 made sweeping changes and, among other things, the engines now must be Turbocharged 1.6 Liter V6's with various energy recovery systems. Mercedes was especially innovative in handling this, splitting the turbine and compressor on opposite sides of the engine which provides numerous benefits, as explained in the YouTube video.

Not mentioned in the video is that there's also the thought that since the MGU-H (an energy recovery system which captures energy from the turbo) is in the middle, that Mercedes can decouple from either the compressor or the turbine as it so chooses. This would mean that when you want to drive the compressor alone you can decouple from the turbine and send all the power to it. Likewise when you want to generate/ store energy, you can decouple from the compressor and drive the MGU-H with the turbine.

While on the topic of interesting turbo technologies, I thought this video on a Koenigsegg 3D printed (titanium and stainless steel, not plastic) variable turbo was interesting too.
