Mclaren MP4-30 Honda

[hurril]

From what i have heard Arai mentioned that the engine is reliable and the problem is discharging the 4MJ... it simply overheats ruining the sensors. He also mentioned making the connections/cables fatter to solve the issue. The biggest performance gains in F1 2015 would be too develop a more powerful ERS sytem as this is relatively new to F1 technology and allows scope for improvement, Honda too have expertise in this.

I think Honda may have a monster of an ERS (a sign of this might be the accelerator being kept on under braking? or that it burns every system/sensor it runs through on full discharge?) Battery cooling technology could be a limiting factor if they have pushed the envelope... Batteries dont like to be repeatedly charged and discharged at such heavy loading and if they went for a performance approach they tried inventing something that at the moment isnt working, like trying to cool a GPU with no fans...

Ron mentioned that you can barely see the MGU-K on the engine, the way it is tucked in tight.

No more pictures of it than the one?

If they are saying the ICE is sensitive to intake temps, I am going to assume the intercoolers are not as good as they could be. Packaging trade-off?

The heat issues sound like a MGUK cooling circuit and or system redesign.

My understanding of Arai words is that the MCUK is in such place that is creating additional heading issues to the air inside the intake and the heading sensors in the intake trigger some warnings and put the ICE on fail mode or something similar.

My feeling is that the MGUK is in the middle of the "V" of the ICE, that place must be really difficult to cool down, no only to feed fresh air but more important to extract the hot air without affecting other components of the PU.

What's the point of putting the MGUK in the middle of the V. Sounds like a bad design to me... not only that it may have/cause heating problems, but also it is a mass that you put high,instead of putting it down low to keep the center of gravity as low as possible.My guess would be that they probably put it as down and as forward as possible - it's easier to collect power like that,and keeping the center of gravity low... cooling would still be problem though

@maguetox: I think you are confusing the MGU-K with the MGU-H. The H interacts with the turbine and is put in the V of the engine for some designs. The K interacts with the crankshaft, so needs to be put very close to it, so will most likely be very low down for better weight distribution and ease of connecting it to the crankshaft.

[RickRick]

Could they have found / made enough space to put the MGU K direct onto the forward end of the crank shaft? you'd be very hard pushed to see it there it would almost be inside the fuel tank

What are those silver patches made off, and for what purpose ?

[dren]

p.s. really dont think McHonda would have this many issues unless they are trying something completely new. just have to wait and find out.. so annoying

It is completely new to Honda.

button last lap(best lap) nothing was changed the ERS, 'saved mode' on the fuel. Mcl honda have trouble with fuel consumption????

In short Button saved fuel due to a detuned ERS on the car which couses bigger fuel consumption of ICE.
The lap that Button did was very good because all they did is unlock the fuel limiter to max but ERS stayed detuned,reason for optimisam in future i would say.

I think those are the 3d printed sections. usually a sort of sintered metal or plastic. When teams want to make parts quickly especially for testing, they would use the 3d printer to make them instead of laying up carbon. The parts are not as strong or sometimes not as light as the carbon parts, but the compromise is usually worth it if you are just testing the aero performance of multiple parts and you want to test many or you want to get it out the door in a short time.

Hmm.. Honda like making flat motors in their road cars... I wonder if they have the MGU-K behind the clutch.



Moment of inertia is high... but the Fomula 1 unit could be much much smaller and lighter...

It kind of looks like it's painted on to me

[PhillipM]

That's where it's been filleted in with epoxy.

If I had to guess, I'd say they have gone for a Mercedes like split turbo, that sits higher in the 'V' with the MGU-K fitted lower down within the 'V'.
