Mercedes Turbo is the compressor at the front?

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

Mercedes Turbo is the compressor at the front?

Post

This is what we have been told by analysts since last year But look at this image from
http://www.mercedesamgf1.com/en/car/pu106a-hybrid/ of the 2014 engine:

Can anyone shed light on this?

So it looks like Mercedes were trying to mislead their rivals with this picture!

The picture in the first post is just for marketing purposes and it has no correlation to the real power unit.

that picture is total rubbish. the exhausts feed into the turbine which is closest to the engine, where does the exhaust gas go after that? into the V? hardly likely!

Just visit the Mercedes Engine Thread, there are Pictures of the actual Engines raced in F1. Not just marketing rubbish.

That video clearly shows a compressor housing at the front of the engine. What is especially interesting is the A/R ratio of the compressor housing. It has a very large diameter. The turbine housing is much smaller in comparison, so it seems there is some method of varying the speed between the turbine and compressor.

I do not think so. It's not different than other turbochargers. Maybe except the one which is not working properly.

thats against the rules. the compressor and turbine have to spin at the same angular velocity

It is difficult to judge the A/R visually. The reason the Mercedes compressor looks so big is that the diffuser is radial. Most turbocharger compressor housings are "folded (rolled)" to reduce the outside dimension. Mercedes packaging has allowed them to avoid this step. Here is a comparison of the two shapes.

A better image of a compact volute. You can see that the diffuser section is contained within the volute.
