Maserati has just revealed its new twin Turbo 3.0-litre V6 that will power the MC20 super Sportscar

🚨 It is the 1st commercial Engine with Prechamber also called Turbulent Jet Ignition (TJI), a very popular Technology since its usage in F1

Some technical details:
➡️ Passive pre-chamber (TJI, Turbulent Jet Ignition) 🌬: a mini-combustion chamber is set between the central electrode and the traditional combustion chamber and connected by a series of specially-designed holes (seems to suggest that it is embedded in the Cylinder Head and not a separated Engine part). This specific PreChamber design is detailed under the patent US10612454B2
➡️ Lateral sparkplug 💥: a traditional sparkplug ignited the mixture when pre-chamber is not used (low loads, cold start, etc)
➡️ Twin injection system 💦 - direct + indirect injectors: PFI 6bar + DI high injection (for gasoline) 350bar = noise reduction + lowering particles

In addition, we learn:
➡️ V90° 3-litre, 6-cylinder twin-turbo
➡️ Compression ratio 11:1
➡️ Stroke = 82 mm; Bore 88 mm
➡️ Double Over Head Camshaft with variable valve timing
➡️ 210CV/litre
➡️ 630CV at 7500rpm 
➡️ 730 Nm of torque from 3000rpm 
➡️ Dry sump
