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.

Interesting comments in the press conference - Bottas said they couldn't run high engine modes (for cooling reasons), and had to lift and coast often. Compared with Max and Honda who ran mode 11 for 30 laps. It's a good sign concerning the cooling and the entire package.
There could be a reliability trade off here--with the engines needing to last several more races. Cooling issues may be a way of saying posterity and long-term strategy. In future races Merc may be choose to switch on their higher engine modes for a return to normal pace. However, the Honda unit may indeed now have improved efficiency, lowered cooling requirements. Time will tell.

That's probably a factor, but I thought it was notable that Bottas explicitly described cooling as the reason for turning it down now. I suppose he could have meant "the long term affects on reliability due to operating in high modes at this temperature", but to me it sounded more acute than that.

curious to think this PU has some advanced A.I, they are bridging failures now the PU reboot or going in safe mode for few second then bridge the failure and restore maximum power.. not the first race Max complained from loss of power then restore power rapidly.

It was just a failed sensor on the exhaust I sure. Is not intergral to the running of the engine.nice victory for Honda last week some people were calling them to leave

A great victory for Honda, impressive that they could run for longer while Ferrari were in fuel-save and Merc had turned their engines down because of overheating. Great Race as well.

A failed sensor triggered a safety thus limiting the engine severely.

Mode "Fail 03" is a setting to be dialed on the steering wheel by the pilot.
It resets the engine to default and ignores the sensors readings/output.

Will be interesting to see how much longer this power unit lasts. Should tell us something about how hard it was actually pushed in Austria.

Tanabe: “We were on the edge on terms of cooling,” he said.
“Of course, the high temperatures forced us to save the power unit.
We tried to extract as much power as we could."

The engine therefore can deliver even more power. :)

Since they started in Paul Richard, by Spa, Monza that's 5 or 6 races total. If it lasts until then mission almost accomplished!

I guess that every cylinder has it's own O2 sensor.

This question was asked on the F1technical subrddit recently. Take of it what you will.

That being said, nothing stops them having their own monitoring and sensing equipment installed.
