Honda Power Unit Hardware & Software

Boulier said Canada PU upgrade(token+fuel) will give 0.3 sec.

Renault is expecting 0.5 sec

They have a second upgrade in SPA...so another .2 sec?

[GoranF1]

Max Verstapen says Renault PU is better than 2015 Ferrari in TR.

All the Honda better than Renault story can end now...Honda is worse engine on grid.

Didn't Merc say that the Honda engine is faster than 2015 Ferrari PU?
They had the GPS data to prove it?

i dont buy it...maybe peak HP ....but in race condition 2015 Ferrari engine looks way better

the only positive thing after this engine fail Alonso had it seems Honda will have to speed Canada upgrade to Monaco.

“Disappointingly for the local fans, Fernando was unable to score points today, owing to a software command issue that stopped the ICE. Until that moment he’d been driving hard and well, and, but for the problem that ended his race, may well have also finished inside the top 10."

Does that mean the PU can be used again?

Depends. They will check for damage

"Alonso retirement caused by software issue, engine undamaged"

who is responsible for the software issues? Honda or Mclaren?

Mclaren ECU, Honda mapping.

[wuzak]

Honda have confirmed that they only have a supply deal with McLaren for 2017.

Mercedes has confirmed Williams, Force India and Manor (and themselves, obviously).

Renault are happy to keep supplying Red Bull.

It is looking unlikely that Honda will supply anybody else, unless Ferrari can't do a deal with Sauber or STR. Though I think Sauber may have a deal in place.

McLaren are supplying the ECU for the whole grid correct ?

[godlameroso]

Last time I checked.

[R_Redding]

Its probable that the software command issued, was to cure sensor failure...

"Alonso said the team was managing the problem before the engine cut out.

"A couple of laps before we stopped there were some sensors failing and I had some message from the team on the pit wall and we were managing the problem somehow but in the end it wasn't foreseeable anymore," he said."

Cassio badged Honda Pu for next year anyone?

Honda must have tried HLSI which is there concept from 2013 on F1. They must have tried to achieve a homogeneous AF within the cylinder to achieve HLSI. In there concept they needed the port injection to be far away from the cylinder to achieve a perfect homogeneous AF, they even tried an atomization nozzle. They also had trouble burning all there AF in the lean mix.

They idea was to increase the temperature before TDC to over 1000K, decomposition of H2O2 produced OH radicals which promoted combustion.

Not sure if they have given up on it or still pursuing it.

and ......
the energy balance chart is misleading (in suggesting the relative efficiency of HLSI)
showing the HLSI benefitting at low power from the absence of throttling vs the stoichiometric engine suffering by throttling to the same low power
the original Honda paper (not the extract by green car congress) made this clear (this we established 2+ years ago)

the bull point of HLSI was (its goal) to avoid production of NOx 'engine-out', and so avoid needing NOx treatment
(stratified charge will produce NOx 'engine-out' because the temperature peak reaches the NOx-critical level)
