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."

Literally the last cars sold in the US that still could burn leaded gas. And they achieved that efficient combustion even with an analog carburetor. Kudos to Maserati for pushing the efficiency of internal combustion engine design.

@@DarkAttack14 This is why you have (need) turbocharging. TJI as an NA engine limits BMEP, but it allows much greater BMEP with turbocharging w/o detonation.

@@DarkAttack14 Sorry for an unclear post - -but happy it was amusing 🙂 I was referring to limitations of spark ignited engines. Diesels can and actually do detonate, but it is controlled(eliminated) by injection rate limiting so the burn rate is controlled by injection rate. The idle clatter of old was due to rapid injection of all the (idle) fuel and sudden heat release of the entire charge. Now, there is a pre-injection, (called pilot) that becomes the fireball for the main charge. Detonation will produce rapid rate of rise in combustion pressures and eat piston crowns. Not widely know by the public.

@@billl7551 diesels do not detonate unless in seriously bad condition. detonation refers to ignition before intended which can't happen in a motor that doesn't inject until intended lol now if you're running an old style Bosch VE pump and your timing is way off yeah you could detonate..

[@evbrower]

The twin spark plugs and their timing is fascinating. The prechamber with its fixed orifice sizes may have an ideal precombustion pressure differential to the main chamber for best efficiency. Lighting the main chamber plug first would build some preliminary pressure to "stuff" more air and fuel up the prechamber. In theory at least, that could bring the prechamber pressure up around what it would be under higher loads, in essence increasing the precombustion discharge velocity back into the main chamber again. Like a high tech hiccup haha.

The real reason the main chamber spark plug exists is at low loads, the piston cannot "compress" the mixture into the prechamber. A piston is actually getting sucked upwards at part throttle, and then at TDC the mixture may only reach atmospheric pressures. The engine simply wouldn't run smoothly or at all at part throttle.

[@ptviwatcher]

Pre-chamber exhaust gas clearing was my first concern when I saw this: there must be some shock wave effect that scoops exhaust gases out before the next cycle, because as the piston goes up that air does not seem to be expelled through the exhaust valves. I suppose dirt accumulation may be solved with a simple cleaning mechanism during periodic maintenance when the spark plugs are replaced - huge advantage of having a small and simple pre-chamber, around the same diameter as the spark plug!

[@Shaun.Stephens]

Easy to clean during service was my thought. All it would need is pull the plug, a squirt of solvent/fuel and a (maybe brass) wire brush shaped to suit the chamber in a power drill (or similar). Owners of these sorts of cars are going to get them serviced regularly and are unlikely to do huge distances so it's no big deal.

[@dr_jaymz]

@@Shaun.Stephens they will also rev the arse off the engine which will help. If you were just town driving I think it'd have a problem, although it still has the second plug so it should still run until you can open up the taps.

[@anthonycanalese2142]

Putting on my Engineers hat, I would say that some detailed Computational Fluid Dynamics (CFD) would have been carried out to analyse this very issue. Also, remember that the fluid being forced into the pre-chamber is an air/gasoline mixture. All gasoline fuels contain some detergent additives/effectiveness in order to clean soot. Combined with the fact that the velocity of the expanding gas jet from the pre-chamber will be relativity high, thereby aiding in the cleaning of any soot. However, as the pre-chamber is so small 10-> 15ml and the jet paths are quite narrow, I would hazard a guess that there may be some long term issues.

[@robertolucignano3495]

@@anthonycanalese2142 , that Is exactly what happens, but if you think about It , wall wetting Is what produces soot. So there should be the problem of soot depositing on the prechamber nozzles. But since you are burning everything with the flames you dont suffer of soot nucleation around the prechamber. The main problem here Is temperature an pressure at Turing. so probably in future we Will see diesel like pistons(stainless steel).

It's so much more intuitive lol I don't know why more people don't do it.

[@pistonwristpin1]

cb350f actually with Maseratis, its a once a year oil service interval. Don’t know what the Netuno uses but the V6 in the Ghibli uses a 7-9gt oil pan, and they use 5w-40 synthetic oil (less coking that way especially in turbo’ed engines.) If you figure the average use of any car is about 12-15k per year, is one of the longest service intervals I’ve heard of, next to the Chevy Volt which has to tell you when to change the oil by remaining service life. After 6 years of ownership, still haven’t replaced the spark plugs (mainly cuz the engine is hardly ever used), no 30,000 mi plug change. As far as time change automotive items goes seems is a better interval, plus Maserati has GT and Indy car test results. Average drivers are easier on Indy cars. And would rather service my car before it breaks, than trying to find a ride home.

Using the right materials with a passive design is better than active combustion, in general. Reliable, robust, outweigh upfront cost (which is way overblown so they don't have to do the work). Commercial turbine engines don't need a catalytic converter and end up beating ground vehicle emissions because they use lean mixtures with small droplet sizes, which means high droplet boundary temperatures (where the ratio is near stoichiometric) are less common and produce less NOx, which is an endothermic reaction.

[@markchip1]

One thing I couldn't understand was how the pre-chamber ever gets its fresh fuel/air mix in, as all I can see is the persistence of spent fuel/air/CO2 inside the chamber once the spark has occured!.... Then you finish by saying exactly the same thing!!!

[@ImaadAnsari]

Hmm so maybe that's intentional? I agree that in the exhaust stroke there will be burnt air/fuel mix inside the pre chamber. However, during the intake phase, these should all be sucked out into the main chamber and get mixed with the fresh air/fuel mixture. And because the relative volume of the pre chamber is so small, the amount of burnt air/fuel mixture should not be too much to cause a problem.

[@SvdSinner]

@@ImaadAnsari Absolutely. I can't imagine the ratio of the precombustion chamber to total cyclinder volume being high enough to have to worry about refreshing the gases beyond what expansion and compression already do.

A Maserati with twice as much going on? I don’t see anything that could go wrong with this (sarcasm)

[@flyingvengeance]

Seriously. ANYONE who has been around and seen what a normal Maserati looks and runs like after a couple years would know better than buy this. The engineering might be great but the electronics and transmission and quality of construction are going to kill any good engineering. Back in the 70's they were considered poorly built wrecks but still cool. What does the name "Maserati" really bring to the mind of a new buyer who is below the age of say 40?

[@brois841]

@@flyingvengeance when I lived up north, I barely saw them and thought they were... meh. One of my co-workers had a Quttroporte(?) which he loved but didn't do much for me. Now that I'm in the sunny South, I see them everywhere... like tons of them. To me they represent a level of exclusivity a bit beyond BMW/Mercedes/Audi. Their styling is very sports-influenced, which is nice. From a reliability perspective I have no idea, but reliability has gotten so great lately it really doesn't matter that much unless it's something major. But what do I know... I have an MC20 on my mind while I'm solidly a Tesla guy now and will probably (realistically) getting another Tesla. The way they drive on the street is just perfect, but on the track I obviously prefer ICE ;)

[@Matticus289]

Begs the question: How much more efficient could our cars be if emission compliance was not in the equation?

[@hola155555552]

Probably they will be less efficient, because there is no need for making an engine efficient if they dont have to comply with emissions, just throw a bigger engine or put a turbo instead of making it more efficient. Any way, the efficiency will be arround 50 % look at the Mercedes F1 engine, is the most efficient car engine and formula 1 cars don’t have to comply with emission. The incentive for making an engine more efficient is better use of se gasoline more than just making pure power.

[@Rickcrazy100]

Matias B he was talking about FUEL efficiency...the mercedes engine you mentioned has 50% THERMAL efficiency...in order to create more power, but still comply with the rules that F1 proposes...two different things my friend

[@hola155555552]

Rick well my friend, in that manner you right. But in order to make a car more fuel efficient it has to improve its thermal efficiency, so it can extract more power/energy out of the gasoline. The emissions sistems makes a car less efficient because they produce loses in the combustion cycle, so the engine extract Less energy from the same amount of fuel, for example rich mixtures for reducing temps lean mixes for reducing CO2 or dumping crude fuel in particulate filters. Any way, I was think in an other thing when I read Loomies question, but referring at what he really asked, the answer is 10 to 20% I have friends that ripped out the emission systems and thats what they gained.

Thank you, what a great video! I am about to buy the MC20 and wanted to break it down to the smallest detail. Given this, your video explains one of the biggest questions - why on the videos of the car the RPMs fall so slowly. Right now, I guess its could be ECU strategy for either warming up the catalytic converter (the car has just started and the test pilot gave it revs) or it could be emission/noise strategy for vehicle being stationary (like Porsche, which opens exhaust valves strictly under load when moving). The engine doesn't appear to be so "sluggish" once it gets going doing rounds around Modena square.
