Maserati MC20 (First TJI roadcar??)

Post

Maserati just unveiled their new V6 engine to power the MC20 supercar, it features F1 derived pre chamber combustion

Is this the first roadcar to use TJI combustion??

But when will Project One hit the road??
And did Mercedes have TJI on the early version of the engines which the P-One is based upon??

I don't see anything new around the TJI. What is it that's earth shattering about this?

It may pre-date the AMG One as the first car with a TJI/pre-chamber ignition system. It will all depend on when the MC20 launches vs the AMG.

Nothing earth shattering? Just thought it was interesting

Pre combustion chambers have been in use since 1930’s , nothing new 🤷🏼...

Yeah, like almost all diesel engines in passenger cars before the volkswagen tdi diesel engines came out have pre combustion chambers, or industry diesel before common rail came out all over the globe

Yes in Diesel engines, it's not commonly used in petrol engines.

Yes TJI is a potentially game-changing technology. There is nothing that can match its combination of ultra-lean burn with rapid and complete combustion.

Pre chamber ignition has been in use in industrial large bore natural gas (SI) engines long before F1 for similar reasons - to address slow combustion speed given the size of the bore.

From the spy shots of this thing, it looks to me a lot more compact and "4C like" than a lot of these giant surfboard supercars. I like that. :wink:

It's also been used in liquid fuel rocket engines long before that. That said, different application, different technical difficulties.

Found this quote from an earlier paper on TJI. It explains the benefit of the extra spark plug external to the pre-chamber.
.
Additionally, a new concept in “Spark Assisted Jet Ignition” combustion was proposed to enable stoichiometric boosted high load operation, where the jet igniter is coupled with a conventional spark plug. With this concept, some of the main chamber charge is consumed first using the conventional spark ignition flame propagation process, with the remaining charge consumed by the jet ignition process Figure 14. Two possible configurations for “Spark Assisted Jet Ignition”, where some of the main chamber charge is consumed using the conventional spark ignition flame propagation process and the remainder using jet ignition combustion in order to increase the burn duration and reduce the heat release at stoichiometric boosted high loads.
