It could refer to the prechamber, but i don't think it does. Generally what often is refered as inserts when it comes to combustion engines are things like tungsten weights which are welded or glued into the crankshaft as counterweights. You can gain an advantage by using them in masses because basically it keeps they size of the counterweights down which improves the aerodynamic of the crankshaft.henry wrote: ↑20 Oct 2018, 10:16I think this is the reg that @godlameroso referred to:
I’m not sure that it specifically covers a pre-chamber, but there are no other regs that restrict the combustion chamber area, other than the requirement for a spark plug.5.1.11 An insert within a PU component is a minimal, non-dismountable part whose function is solely to locally support a function of this component. The total volume of inserts within the component cannot be more than 10% of the total volume of the component.
https://www.motorsportmagazine.com/opin ... ine-updateWithin the F1 regulations, only a single injector is permitted and the key to applying the principle within that limitation was shrouding only the spark plug to form the mini-chamber above the main combustion chamber and not – as in the drawing – the injector and spark plug together.
No, not forcing. But Marko has given Honda free hand to introduce new parts in the remaining season even if this leads to grid penalties. But the decision is on Honda and not RBR.
"How they got around the single injector role" Yes you are correct. that was after his attention was drawn to the rule stipulating "direct injection" must be used, and in turn the Mahle TJI pre-combustion system came about a week after pushing out the use of HCCI combustion system. all this happened something like 2 years ago.McHonda wrote: ↑20 Oct 2018, 19:29Mahle openly talked about using an adapted version of TJI for F1 regulations back in 2016.

Yes they for sure will, in fact i have no doubt that the other 3 manufactures will also be working flat-out to that end.godlameroso wrote: ↑20 Oct 2018, 21:34There's about 5 months left until winter testing, I'd imagine they'd be working flat out to get the best PU they can until then.
Sorry if I've got the wrong end of the stick here but if you know Mahle said they are using an adapted form of TJI 2 years ago already then why do you doubt the use of pre-chambers in F1?saviour stivala wrote: ↑20 Oct 2018, 21:18"How they got around the single injector role" Yes you are correct. that was after his attention was drawn to the rule stipulating "direct injection" must be used, and in turn the Mahle TJI pre-combustion system came about a week after pushing out the use of HCCI combustion system. all this happened something like 2 years ago.McHonda wrote: ↑20 Oct 2018, 19:29Mahle openly talked about using an adapted version of TJI for F1 regulations back in 2016.

As a point of interest what do you think “shrouding the spark plug to form a mini chamber” is other than a pre-combustion chamber?saviour stivala wrote: ↑20 Oct 2018, 21:18"How they got around the single injector role" Yes you are correct. that was after his attention was drawn to the rule stipulating "direct injection" must be used, and in turn the Mahle TJI pre-combustion system came about a week after pushing out the use of HCCI combustion system. all this happened something like 2 years ago.McHonda wrote: ↑20 Oct 2018, 19:29Mahle openly talked about using an adapted version of TJI for F1 regulations back in 2016.

They will. At least out of Honda and Renault, Honda seem happier to throw more resources at the problem.saviour stivala wrote: ↑20 Oct 2018, 21:51Yes they for sure will, in fact i have no doubt that the other 3 manufactures will also be working flat-out to that end.godlameroso wrote: ↑20 Oct 2018, 21:34There's about 5 months left until winter testing, I'd imagine they'd be working flat out to get the best PU they can until then.
