Beryllium in engines drama

[dialtone]

Do you have a source for x rays aren’t harmful?

Is the connection here that beryllium is also not harmful?

Possibly suggesting similar to more people die from chicken bones than Beryllium, but chicken is not feared.

Are you aware that there are regulations for how you are supposed to work with beryllium and that’s why there are fewer deaths/illnesses by it?

This comment section is funny…

That is the very point. If something is dangerous, then it is dangerous.

From memory, Ferrari were using an aluminium-beryllium alloy in their brake callipers, which was banned after 1997. Bt they hadn't developed any aluminium-beryllium engine parts at that stage.

Noting that Mercedes-Ilmor were using aluminium-beryllium parts in their engines, Ferrari sought to have them banned.

The ban was imposed, but allowed 2-3 years before they would no longer be allowed.

So Ferrari developed aluminium-beryllium components for their engine too.

IIRC the ban was from the end of the 2000 season.

Before the AIBeMetam162, An aluminum-beryllium material comprising 62% beryllium piston/liner/gudgeon-pin were developed, this very stiff, very light material had already been successfully exploited by BREMBO to make more effective F1 brake calipers at the suggestion of former Honda engine designer Osamo Goto than working for FERRARI.

*1 season.

On October 6th, 1999 the FIA moved to ban beryllium, giving the teams until the end of the following season to remove it from their engines, though only Mercedes and Peugeot were using it.

Beryllium was banned entirely for 2001

... Beryllium was banned entirely for 2001

afaik
beryllium is still is permitted in concentrations not exceeding 2.5%
ie CuBe for valve seats

The complain by ferrari was not the care about health of the spectators or drivers but the risk to loose against the main competitor mercedes - ilmor .

Why ?

Ferrari in 1999 and 2000 decided to go as large bore and as short stroke as only possible . They ran in 2000 96x41.4 while ilmor ( not officially confirmed ) ran 93.5x43.67 .

Extreme bore to stroke ratios were good for top end power due to higher possible revs but had disadvantages in midrange torque .

Mario illien was a genius . He was aware of this and designed an engine with a relativly large stroke to push midrange torque AND berrylium pistons to cope with the massive piston accleration when trying to rev extremely high for top end output .

In 99 and 2000 ferrari saw that the ilmor v10 obviously has a bigger stroke and better midrange , but simultany despite the bigger stroke reved as high as their ferrari for the same if not better top end bhp.

They finally realized its the berrylium pistons and were in a severe risk to make the wrong decision in going the bore as large os only possible should berrylium stays allowed.

Only chance was to complain about health issues to achieve a ban by FIA

After the ban in 2001 ilmor was doomed with the larger stroke since the engine either blew up or was not top class in bhp anymore .

Finally , after the ban was permanent , all engine suppliers went the path to the bore as large as only possible because it was the only way to further increase rpm,s and so horsepower.

“Bore as large as possible”

This was partly capped by how fast combustion occurs. They got to the point that larger and larger bores were out running the flame front.

Absolutely correct . With "as large as possible" i mean as large as you can usefully control the combustion process , reach desired compression etc .
