Press Release The new generation of engines from Mercedes-Benz

[martinbo]

Crankshaft itself is 360 degrees. I4 has rod journals every 360/2=180. With I6 it is 360/3=60. But it doesn't work with V6, if you understand, what I am saying.

That's I4

That's I6

We have the same length beetween the connecting rods of I4 and I6

Now look at V6 crankshaft. It is completely different from inline crankshafts.

That's what I was trying to say.

I know all of this. So does Giannis. You said this:

You can take I4 crancshaft as a basis and make one for I6. And this is true for every detail. It is called unification.

Based on your exact post above you are contradicting yourself. The is no commonality in machining an I4 crankshaft with that of an I6. None.
For the cylinder block it's a different story - most certainly here modularity can be achieved.

It can't be shorter. It has the same 0.5 litre cylinder as their new V8 engines.

Read the info on this engine cause it doesn't have belt drives for AC, alternator and water pump the overal length is close to a 4 cylinder engine with all belt accessories added.

Guys, can we not turn this thread into an I6 vs V6 one?

Why not make a separate thread and debate this as much you want and keep this one clean?

V6 engines suck. Nothing to discuss

I would be interested to know how much the new inline6 diesel and petrol engines weigh, I am guessing the diesel in particular will be lighter than before as its all aluminium now.

^ Might have to wait until the MB engineers publish in MTZ (Motortechnische Zeitung) which usually includes some weight info.

Car and Driver confirms C/GLC straight sixes.

Look for the new straight-six in Mercedes-Benz models from the E-class upward, starting with the S-class next year. We suspect this engine also will form the basis for a six-cylinder AMG engine to replace the 3.0-liter turbocharged V-6 in the 43-model cars, and in that form it eventually will migrate to the C-class and the GLC as well.

... and an straight six GLE diesel for the USA.

There’s another inline-six that will come to the United States: the 3.0-liter OM656 turbo-diesel, which will make “more than 309 horsepower” but also will be offered in a version rated at 282 horsepower. Look for it in the next-generation GLE.

I'm getting W126 vibes, now MB is coming with a I6 for the W222. My order is already signed

I guess you take the OM656. But you should have a testdrive in a car with the M256 aswell ;-)

On the side note - any news with your S Class? Did they finally resolve the problem?

Thanks for asking @W201, yes they did.

Late to the party...

So looks like Merc is going the route of modular engines based on 500cc cylinders, twin scroll turbos and hot V V8s. VAG/Porsche is also well on that path. And no one thought of giving the Bayerische motoren werke-rs some credit for werking that path?

 

[PanterroR]

^It's because MB always leads, the others follow, Sunny... How come you didn't know that?

Happy somebody finally said it. We now wait for Bayerische Motoren Werke to come out with something else they can copy .

I said it yonks ago. People just don't pay attention.

Well now saying a good word about the brand is just politically incorrect, the Mercdesism has just become too strong.

When will we see the new OM656 i6 turbo diesel in the sprinter?

 

[Wolfgang]

^ May be offered in the new Sprinter generation, which is to start in March of 2018.

Spied! - Next generation Mercedes Sprinter

A U.S. judge in New Jersey on Tuesday threw out a proposed class action lawsuit alleging that automaker Mercedes misled consumers about emissions standards in "BlueTec Clean Diesel" vehicles.

U.S. District Judge Jose Linares said the plaintiffs did not have standing to bring the case.

ADVERTISING
Plaintiffs claimed Mercedes falsely advertised the BlueTec vehicles as having lower emissions. They said that they later found that the emissions were higher than U.S. standards permitted.

The judge said the plaintiffs failed to show they actually viewed any of Mercedes' advertisements touting the cleaner technology. He gave them leave to revise their complaint.

Diesel car makers in the U.S. have been under increased scrutiny since Volkswagen AG admitted in September 2015 that it had rigged U.S. diesel emissions tests. Volkswagen ultimately agreed to pay US$15.3 billion in settlements for owners as well as state and federal regulators.

In April, the U.S. Department of Justice asked Daimler to investigate the emissions certification process for its Mercedes vehicles. The automaker said it would cooperate with U.S. authorities, but has not admitted to any wrongdoing.

The BlueTec system uses urea to eliminate nitric oxide fumes from vehicle emissions. It is used mainly in heavier cars like sports utility vehicles or Daimler’s large limousines.

ISG – The next step

A Volvo invention, the Integrated Starter Generator (ISG), was demonstrated at the Frankfurt Motor Show in 2001. ISG can cut fuel consumption by as much as 20 per cent. The most noticeable difference compared with a conventional car is that the engine in a car with ISG switches off completely when the car comes to a standstill, instead of continuing to use fuel at idling speed - for instance, when waiting at traffic lights.

The ISG unit is installed between the engine and gearbox, linked directly to the crankshaft. It replaces both the starter motor and the alternator. In addition, ISG supplies power in operating conditions that would otherwise increase fuel consumption. The ISG system is soon to be reality in ordinary Volvo cars.

Is ISG a volvo idea ?
