Honda Power Unit Hardware & Software

The burning catalytic converters on the billions of cars on the road means there's small amounts of platinum laying on the ground.

Regarding Honda, the smoke wasn't coming out of the tail pipe but what seems to be the breather.

rumours of a turbo change, due to Mguh failure.

Don't know what that is but that's 100% false because Tanabe said they would send the power unit back to Sakura for investigation in the post race interview (from which you can just deduce why that is false or easy technical guess anyone can make out of known facts ie mgu-h hardware failure/breakage).

Thats a speculation based on assumption that if there is an issue with MGUH, reported as an anomaly by Tanabe, they will have to also change the turbo due to the construction. That was my question preseason, has Honda designed the new PU with interchangeable components?
The reporter suggests maybe not and any issue to MGUH or turbo would mean replacement of both even if one is healthy. Renault for sure can replace any of the PU components independently.

How much damage did Hartley have?

How much time did it cost him?

It sounds much more like an excuse, rather than a reason.

He had a damaged floor.

You’re better than this wuzak, what’s your issue here?

Did he?

How did that happen. As far as I can tell, he didn't go off the track.

He had a flatspot, but that shouldn't damage the floor.

I just can't see how this was a positive race for Toro Rosso or Honda. They are still some way off.

Explanation was he hit the kerb and damaged the floor. the damaged bodywork punctured his tire.

Is that just before he retired ? To me it definitely looked like exhaust pipe/ wastegates.
If those puffs were from the breather the ICE is kaput.

[godlameroso]

Yeah he was pulling into the pits in that shot.

Hello Wazari. Are turbo rpms slower this year in the new engine? And has Honda imolemented the ideas from the aviation department yet?

[hecan]

Renault had a turbo failure with lots of smoke in testing with McLaren, it did not require a PU change. Gaslys' engine was running when he got back to the pits, so it might not be a complete PU failure, rumours of a turbo change, due to Mguh failure.

If you're referring to this https://www.motorsport.com/f1/news/mcla ... s-1020322/ it was just tissue that burnt inside the air duct on the Mclaren

Didn’t the failure occur halfway through the lap? I’m not sure if I’m imagining things but didn’t Gasly make it back to the pits under his own power despite the failure? Seemed like the ICE was still functional.

Point is it's not the bump that caused it, bump was just the final straw. Not worried about it, sure it's a shame they're one PU down, but not a big deal in the grand scheme of things.

Well, one PU down out of 3 with 20 races to go is still pretty big in the grand scheme of things.
And they are not blazing quick either.

It looks like the same sort of MGUH issues they were plagued with last season. If this really is a design issue, the replacement Turbo/MGUH is bound to be the same spec as the one that failed.

I suppose that's what the mid season upgrade centers around rectifying. It really isn't a big deal, it's obvious they're backmarkers, so penalties do nothing to them in the grand scheme of things. If everything is perfect they qualify near the back, if everything is a disaster they qualify at the back. Even if they take new engines and penalties every race it has no impact on their qualifying performance, but it can certainly move them up the grid during the race.

Did it happen before ? Did they explain What caused it ?

First sneak peek I found of the RA618H. Hope we can get more during the season.

Definutely air to air intercooling. Will they ever go air to water is a good question.

[J.A.W.]

Well, seems that Honda sticks to founder Soichio-san's racing dictum (as recently quoted by Kevin Cameron),
"More is to be learned from failure, than success."

[restless]

Are there other teams that use air to air ?

[muramasa]

That youtube video is a collection of stolen pictures..

That radiator on the spine is gearbox and ERS cooler, not intercooler. Intercooler must be on the left sidepod if the layout is unchanged from 2017 unit.

I found in 2018 FIA Technical regulations that F1 engine must have cylinder diameter of 80 mm, but I didn't find anything about stroke.

Renault and Ferrari state that their stroke is 53 mm while I didn't found data for Mercedes and Honda. Is this 53 mm stroke also regulated or is it just a coincidence that Ferrari and Renault engines have same stroke?
