Maserati has published additional details on his PreChamber technology deployed in the new MC20. The complete details on the MC20 car as well on the Nettuno Engine is available here

➡️ PreChamber development started in 2015 and the 1st bench tests were already running in Sept 2015
➡️ PreChamber immediately showed benefits at very high loads (more power 💪🏻) but made lower loads more unstable
➡️ That is why a 2nd Spark Plug 💥 has been added in the main combustion chamber for low loads
➡️ Maserati has developed its own advanced controlled strategy 💻 which ended on a new patented technology
➡️ In mid 2017, Maserati transfered this techno into a prototype vehicle 🚘 for in-production development
➡️ The final results are higher efficiency, more power and fuel economy (about 3%)
➡️ Additional cost of this techno: about 150 euros in this specific engine

Key information on Maserati Prechamber:
➡️ PreChamber cooling ❄️ is crucial so that the material choice for the PreChamber insert is key. Maserati uses copper alloy because of its high thermal conductivity (heat is rapidly dispersed)
➡️ Additional cooling is available from the cylinder head cooling jacket
➡️ Choice of spark plug crucial, in particular its material because it also needs to disperse heat 🌡
➡️ Twin Spark 💥 system and its control strategy were key in the success of Euro6d emission compliance

In the interview, Ettore Musu, PowerTrain innovation Responsible, concluded:
"We’ve done something extraordinary. I believe that in the future this technology will be widely adopted, even by competitors“
I deeply agree! 💚🤍❤️
