Honda Power Unit Hardware & Software

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

To fix their problem with the ICE not making power without destroying the pistons=new design Head and Piston Crown.

Help or fix vibration problem=new design trans casing and ICE block.

[quote=MrPotatoHead][quote=JuanjoTS]
In the current F1 turbos the discharge valve is not the main overpressure controller, it is the MGU-H which in recharging mode slows down the turbo speed. The MGU-H should not be the most expensive or complicated, in my opinion should be electronic management, make everything work at the right time.[/quote]
The MGU-H motor is very "complicated" and as a result expensive. The rotational inertia and forces that it has to control during the required acceleration and deceleration times are immense.
It's this combination of moment of inertia and acceleration that blows my mind.[/quote]

imo
there's nothing that makes MGU-H super expensive other than its one-offness of requirement in size and shape (likewise its drive package)
similar technology is available COTS for a peanuts price
development/tuning the control program functionalities for best integration into the race PU is a big expense timewise - for now
overall a situation not very different to what makes eg an NA F1 freeze engine expensive and complicated relative to road engines

regarding accelerative capabilities my guesstimates of system response 'time constants' made from a little experience are ......
the MGU-K accelerating the ICE - about 40 msec
the MGU-H accelerating the turbo - about 100 msec
the time constant is the time taken to reach 63% of any step demand in rpm
the K should thus not degrade shifts in response quality or time
the H should thus not degrade the ICE response to normal demands

btw over 30 years ago there was a quite small UK 'servomotor' (MGU by another name) whose TC without load was 2.7 msec

Tommy - There is quite a difference between an unloaded motor and a loaded one though wouldn't you agree? I've been tuning closed loop PID servo motors for over 15 years and bench tuning a servo motor unloaded is almost pointless.

The first steps were taken in the disputed test in Bahrain last Tuesday and Wednesday. In the McLaren pits they were present (in civilian clothes) external technicians who have supported the Japanese engineers in particular on the electronic front.

I used google translate, basically says something on the lines Honda has hired outsider's help and they were present at the test in civilian clothing and that turn in fortunes might not be a coincidence. Someone who actually knows italian might be able to chime in though :D

They are saying that Honda has changed mentality and that they are more open right now. They had only two possibilities, retire from f1 or hire engineers outside Honda world.
The article claims that during the Bahrain test Honda was helped by outside engineers in the electronics side and this caused a much smoother run for Vandoorne with all the benefits.

After Honda finaly dumped Gilles Simon it could be Mario Illen or the Mercedes advisor team?

First of all I don't really trust the guy who wrote the article, he rarely gets it right with the rumours. If it is true then Mercedes advisory team because the article claims that Honda was helped on the "electronic side". Illen is more a ICE specialist.

Kind of seems far fetched honestly. It seems like Honda didn't know what they were doing and presence of more skilled engineers somehow solved all issues overnight? Sounds weird to me.

Electricians solve vibration and water leak ? No matter names journalist lies more than saying true.
Who knows, software plays a huge role in power unit integration, perhaps these engineers saw something Honda didn't. The MGU-H issues were due to a bad batch of bearings like we were discussing earlier. Once that got sorted there were less issues, the rest is just mapping and that's all software.

Sometimes people that have expertise in a specialized area can help resolve issues that are not apparent when working from a more holistic perspective. An electrical engineer may not know anything about combustion chambers or valve angle or port slope, but understand control electronics in finer detail than an engine builder.

Rumors invented by some journalists.. To Discredit the work of Honda.
I love reading the technical talk, but these rumors are ridiculous
