How Mercedes Made The Most Powerful 4-Cylinder Engine In The World

[@Randpage]

How did Mercedes make the most powerful 4 cylinder engine in the world? Simple. Boost. Boost. Boost, with a generous helping of yet more boost.

[@Error-30h3]

Maybe afterwards we can get some boost to celebrate

[@henryon400cc2]

Ye the boost is important here, but they also had good decisions and ideas presented in this engine , like he said in the beginning in the video

[@D7mo0o0on]

its easy to boost but its hard to make a boosted engine and put a warranty on it

[@Randpage]

Everyone and everything uses forced induction now. I personally don't find it very exciting or interesting myself.

[@afrosheenix]

This thing needs a supercharger though, looks like you have to rev the crap out of it to hit peak torque and hp. My twin charged volvo s90 does it right, minus about 100hp. It can use the supercharger and turbo at the same time and I've seen it pushing 23psi.

[@willchen9014]

In my experience, I’ve found the heat saturation gains from mounting the turbocharger on the firewall-side of the bay can also aid in catalyst light-off and therefore reduce tailpipe emissions. I would not be surprised to hear this was also a consideration with the new EU 7 targets on the horizon.

Great improvements from Mercedes Benz and also by me, because I now understand your drawings and can follow the explanations through them, Jason. Thank You. What is the most impressive technology for me, is the Nanoslide that "sticks" the oil to the cylinder walls that reduces the Friction BY 50%! and the TWAS which also compensates the Closed Deck Heads.

[@itsalgud1459]

Thanks Jason, for explaining some very complicated technology extremely well. The specific output of modern engines astounds me, having become interested in cars in my middle teens in the early 60s. At that time, American muscle was hitting about 1 hp/cu in on the hottest cars (about 61 hp/l.). The fastest European cars were getting close to 100hp/l, which was about what race cars got. I’m fascinated by this technology which makes more than 200 hp/l possible ON A PRODUCTION CAR! 😵

Mercedes has ALWAYS been at the forefront of car technology. They have pioneered almost all major improvements on cars. They were one of the first cars to have fuel injection in the early 1950s.

I have seen many tuners be able to get 450hp out of their 90s K motors and the new type r civic can produce over 350hp with a simple engine tune and while it may not be as much as the Mercedes, its nothing to sneeze at.

Not many people in the world share your talent. My engineering experience is limited to watching nerdy videos on KZbin. The way you compare things is always a relevant comparison, the way you explain things is always so easy to understand but still very detailed and technical. No fancy computer graphics but you don't need to, I can pause the video and analyse your whiteboard and it all just makes sense. Every piece of data you use is valid and if you have to estimate then you research the heck out of it to make sure your estimate can't be more than maybe 1% out. You carefully select the right words to use so there's never any confusion about what you're saying. Every video you make is like this. Really impressive. Thank You.

[@Paul-pj5qu]

At this point I am assuming Mercedes said nothing about MPG and therefore the difference is marginal or not as good. The engine would seem to be more efficient, but is generating a lot more power. I am not an engineer, but it seems the basic answer is what is greater the increase in power or the increase in efficiency?

[@LocPH.]

@@Paul-pj5qu Well power itself has nothing to do with efficiency. Depending on what you're comparing the power increase to, it's probably higher than the efficiency gains. On the other hand, just an increase of say, 5 mpg, is a lot.

[@tejaskulkarni8639]

You did not mention it but for the record, in this engine, the cylinder head is cooled by a separate coolant circuit and the crankcase is cooled by a different circuit. I could be wrong about which circuit is used to cool the crankcase and the cylinder head but I think Lower temperature circuit is used to cool the cylinder head and high temperature circuit is used for the crankcase. So, the circuits are different which help in structural integrity of the engine. Secondly, it improves the thermal efficiency of the engine by using higher compressor ratios. It is possible to use such higher compressor ratios because the head is now much much cooler

[@ryan.crosby]

Port injectors also increase the amount of time that the fuel has to mix, and increase the amount of fuel that you can inject outright. Many high performance engines, including aftermarket setups, use both at once. The fact that the port injectors remove intake valve deposits is a nice longevity bonus so it makes sense to mention it.

Roller bearings fail catastrophically. Journal bearings typically survive a catastrophe, as long as there is flowing lube oil. In my mind, I imagine the difference in contact surface areas and localized stress of the bearing components (journal vs roller bearings). For automotive applications, it doesn’t “really” matter that much either way. I don’t think pragmatically, I think like an engineer.

[@mkloppers]

What I am curious about, is how their "roller bearing" compares to the advantages provided by the "ball-bearing" design that has given Garrett's turbos a distinct advantage over journal bearing turbos. I'm currently still finding ways to expand the "limits" of my GT3040 (aka GT3082) turbo (oil + water-cooled BB turbo), which I installed in 2003 and have never had to rebuild it. It provides 450whp currently on my 2.2L stroker 5sgte, and spools to 200 ft-lbs by 3000rpm... and that is only at around 23 psi... not done yet, it should make over 500whp by the end of this year.
