I was just surprised at the negative votes for an obvious joke. I guess some don't understand your humor. Regardless I upvoted it and let's get back to business.

We have a meme thread for jokes. It is here: viewtopic.php?t=29978&start=15
This is the technical side of the forum so it's quite common for non-technical input to get downvoted or simply removed by moderators. Content filtering is much more strict here than other social media.

I thought it was funny.
I would think everyone knows who is responsible for what's under the engine covers.

The guy in this video claims that F1 engines uses passive pre chamber for combustion. What do you think about it ? When they run engines high rpms and good amount of fuel to fill a passive pre chamber it seems to me possible.

I think he is spot on in theory. Needs to be a little more creative as to where the pre-chamber might be located and if its truly passive.

I like volcano 
like PC in the crown of the piston.
Fuel is injected into the crater with some of it leaking out into the CC.
TDC the fuel in the crater is ignited and flame jets exit the crater to ignite the very lean fuel mixture in the CC.
At the edges of the CC the heat caused by compression and front thermal wave of the jet flames you have thermal ignition.

Sounds like an interesting clue here. Maybe the pre-chambers are really in the valve faces...
Heck, you could even lap the valve itself into the piston, then bump it with the cam to compression ignite it.

@Sasha already stated how the Honda design is likely working.Zynerji wrote: ↑07 Mar 2023, 06:52Sounds like an interesting clue here. Maybe the pre-chambers are really in the valve faces...Heck, you could even lap the valve itself into the piston, then bump it with the cam to compression ignite it.
Volcano (Mt Fuji) piston design with pre chamber in the piston.

Guys watch the Pat Symonds video viewtopic.php?t=30363. The pre-chamber is in the wall of the main chamber and works as per the Mahle TJI system minus the extra injector in the pre-chamber.

Some lovely official shots of the RA621H recently posted on Honda's media website.
