Jonathan Kay Posted April 10, 2014 Share Posted April 10, 2014 Fascinating, thanks. I wonder what else they get up to with that shaft. It might not be a simple locked drive. The electric motor that spins up the compressor has to be connected somewhere. Jonathan Link to comment Share on other sites More sharing options...
elie boone Posted April 10, 2014 Share Posted April 10, 2014 It's a good idea but technically not easy as the shafts spins extremely fast , I would split up the compressor in 2 smaller one's if I want to reduce lag. Give RB another race or 2 and they will be closer to MB. Link to comment Share on other sites More sharing options...
Martin J Posted April 10, 2014 Share Posted April 10, 2014 Interesting, thanks for posting. How long before this technology filters down to an AMG road car? Link to comment Share on other sites More sharing options...
Gavin H Posted April 10, 2014 Share Posted April 10, 2014 It's very clever and makes very good sense. Also very difficult for other teams to adapt to in the year. Which leads me to a question - do all Mercedes suplied teams have this? I had heard that there are differences between the Mercedes team and customers engines - is ths one of them?

Jonathan Kay Posted April 10, 2014 Share Posted April 10, 2014 Quoting Martin Jeffrey: How long before this technology filters down to an AMG road car?The McLaren P1 uses electric drive to the wheels (not to the turbocharger) to fill the gap from turbo lag and similar undesirable non-linear behaviour. I presume the Mercedes-Benz SLS AMG Electric Drive does something similar but I don't know. But for ordinary road cars I predict that electric drive with hybrid sources will dominate. That way the ic engine can run at optimal conditions without constraint from the connection to the road. The F1 approach should wake up interest in this.

elie boone Posted April 10, 2014 Share Posted April 10, 2014 Jonathan, that is quit true but if you need less energy to power up the turbine you could use it elsewhere and your battery pack will be cooler and maybe a little bit smaller. Link to comment Share on other sites More sharing options...
Simon.Rogers1 Posted April 10, 2014 Share Posted April 10, 2014 I wonder why Honda waited for 1 year Link to comment Share on other sites More sharing options...
elie boone Posted April 10, 2014 Share Posted April 10, 2014 Or was it McLaren that wanted an extra year ? anyway something must have triggered the decision. Honda has plenty of engine building skills trough HPD Link to comment Share on other sites More sharing options...
Barbarossa. Posted April 10, 2014 Share Posted April 10, 2014 Quoting elie boone: I would split up the compressor in 2 smaller one's if I want to reduce lag. Quoting F1 Regs: 5.1.6 Pressure charging may only be effected by the use of a sole single stage compressor linked to a sole single stage exhaust turbine by a shaft assembly parallel to the engine crankshaft and within 25mm of the car centre line. The shaft must be designed so as to ensure that the shaft assembly, the compressor and the turbine always rotate about a common axis and at the same angular velocity, an electrical motor generator (MGU-H) may be directly coupled to it Edited by - Barbarossa. on 10 Apr 2014 12:29:33 Link to comment Share on other sites More sharing options...
Jonathan Kay Posted April 10, 2014 Share Posted April 10, 2014 *arrowup*Thanks. So someone was thinking of this sort of architecture. Jonathan Link to comment Share on other sites More sharing options...

Barbarossa. Posted April 10, 2014 Share Posted April 10, 2014 We're going to see a lot more technical details coming out over the next few months. The FIA has realised how little the public appreciate the technical advances that have been made in these new cars and is pushing the engine manufacturers to 'boast' about what they have achieved. For example, the thermal efficiency of these new power units is about 35% over a race distance. To put that in perspective, that is about the same as a modern diesel repmobile cruising down the motorway at a constant 2000 rpm! Link to comment Share on other sites More sharing options...
