The Maserati MC20 Nettuno Engine uses dual combustion chambers, dual spark plugs per cylinder, and dual injectors per cylinder. It's packed with innovative tech, sharing commonalities with F1 pre-chamber engine technology. It's a 3.0L, twin-turbo V6 engine making 620 horsepower and 538 lb-ft of torque. The prechamber technology allows for greater power output by reducing engine knock. Watch the video to learn all about it!
Maserati Nettuno Press Release:
"The new power unit has a V90° architecture, with a 3-litre, 6-cylinder twin-turbo, and features a dry sump (a classic solution on super sportscars). It delivers 630CV at 7500rpm and 730 Nm of torque from 3000rpm with a specific power output of 210CV/litre. The compression ratio is 11:1, the stroke is 82 mm and the bore 88 mm.
The soul of the engine is the innovative pre-chamber combustion system featuring twin-spark plugs. This technology is derived from Formula 1 and is now available, for the first time, on an engine destined for the road.
The engine has three main features:
The pre-chamber: a combustion chamber is set between the central electrode and the traditional combustion chamber and connected by a series of specially-designed holes.
Lateral sparkplug: a traditional sparkplug acts as a support to ensure constant combustion when the engine is operating at a level that doesn’t need the pre-chamber to kick in.
Twin injection system – direct and indirect: linked to the fuel supply pressure at 350bar, the system reduces noise low down on the rev range, lowering emissions and improving consumption."
