Today's engines in F1 are some of the most powerful ever seen in F1, producing over 1000 Horsepower, despite using an engine that could fit in your everyday road car. But how is this possible?
The secret is much simpler than you might expect, but it’s also SO, SO CLEVER.
So, let me explain.
Formula 1 teams are constantly trying to find grey areas in the rules to give themselves a competitive advantage and this genius innovation gave quite the advantage.
The Formula 1 regulations changed massively in 2014 when they introduced the Turbo Hybrid Era. Before this, F1 cars were powered by normally aspirated, 2.4 Litre V8 internal combustion engines.
These engines were limited to 19,000 rpm and produced about 750 bhp.
The 2014 rules shrunk the engines to 1.6 Litre V6s and limited them to 15,000 rpm. They also introduced turbos back into the sport for the first time since 1988 to help compensate for the loss in power output from the smaller engine.
But the biggest change was using electrical energy to partially power the new ‘Power Unit’. This came in the form of an MGU-H and MGU-K with MGU standing for Motor Generator Unit. It was expected that these ‘Power Units’ would maintain the power output of F1 cars at around 750bhp.
The rules also restricted how much fuel can be used in a race, 110kg, and how quickly that fuel can be fed into the engine, or fuel flow rate. This was capped at 100kg per hour and strictly monitored by the FIA.
However, what the rule-makers left out was anything restricting the ways in which the teams could manipulate this 110kg of fuel to get more power from it and Mercedes found a way to do exactly that.

Higher octane fuel doesn't have more energy it just has more protection from detonation which allows you to run higher cylinder pressures without blowing up your engine. Also, lean fuelling can also cause detonation which is a bigger issue than anything you listed.
@forbiddenera Рік тому
And what you describe is basically just stratified charge on crack not a new idea just a new (and im sure better) implementation
@Appletank8 Рік тому
Higher octane allows for higher compression, which does allow you to extract more energy out of the fuel. Also, I’m sure the engine designers have mapped out the maximum amount of fuel they can inject into the main chamber that doesn’t detonate at those temperatures and pressures until they actually want it to. Which again, the higher octane helps with.

A separate pre-chamber into which the fuel was injected was how diesel engines used to be made. Hot bulb engines also works in a similar matter. It is also worth noticing that the actual speed of the combustion increases as the mixture goes leaner, this is due to the relatively higher amount of oxygen available. Drawback of lean burning in everyday use is the emissions since it creates a higher amount of NOx.
@ajwasp3642 Рік тому
......or like the Honda cvcc?
@jfess1911 Рік тому
NOx formation is increased by high temperature and pressure. When leaning out the mixture far enough, the combustion temperature begins to drop, actually reducing NOx. This is how the Honda CVCC engine avoided needing a catalytic converter to deal with NOx. This was not good enough to deal with the later, tighter emission standards, though. My understanding is that current emissions controls need near stoichiometric to have the correct ratio of chemical byproducts for the catalytic converters.

A/F mixture in that game may be misleading; I don't know if the drivers actually mess with that, as it is typically tuner/engineer side, relative to other aspects. A/F ratio can produce some gains, it's part of the whole picture. You were talking about pre-chamber tech that helps to distribute flame travel across the chamber and piston. The 4-valve engine having advantage of a central sparkplug aided by distribution of multi flame fronts, for increased burn of less fuel, for less vehicle weight; or they're not decreasing injection rate and seeing some power gains. It's not that great for road cars, unless the F1 engine is improved more at high rpm timing of spark/fuel duration, improving boost parameters. And if the ICE power can then be balanced better in practical app of the electric power, then more rwhp is available more often for use against opponents. It's a whole system application. Cheers. PS Also it gives advantage after reduced speed/flag conditions, regarding power mode selection duration - available fuel. Relative to someone who doesn't have it. But the teams could still see advantage, depending on how they're using it.

@jgonzalesm6 Рік тому
This video has a bit of parts missing. 1) The V-8 era wasn't just the ICE. KERS was introduced in 2009. KERS stands for Kenitic Energy Recovery System which had an MGU-K and recovered energy under braking. 2) The 2014 turbo hybrid era. No one was really into hybridization i.e. Italy(Ferrari), France(Renault) and Japan(Honda came in 2015). Mercedes(Germany) were into hybridization and started in 2007 developing this turbo-hybrid formula according to what Niki Lauda told Luca di Montezemolo. Then you throw in the token system(2014 thru 2016....3 years) which hampered further development to everyone which gave MercedesAMGF1 their dominance. It wasn't until 2021, that RedBull-Honda FINALLY caught up to MercedesAMGF1....so 7 years of MercedesAMGF1 dominance. Honda "copied" the split-turbo from Mercedes in 2017. Renault followed suit. In 2023, Renault is playing catch up. Ferrari is the only team that HAS NOT copied the split-turbo design and were plagued with reliability issues in 2022 to include their teams. MercedesAMGF1 engines are still reliable in 2022 to include their teams followed by Honda. An example of this turbo-hybrid era is like asking the teams who can make the best Lasagna since we all know Italy has been making Lasagna for a long time. Then the rules for 3 years was that no one can add any ingredients to their Lasagna. Who do you think will win the Lasagna challenge? Yes, everyone agreed to the rules but no one realized the dominance MercedesAMGF1 would have. Now it's 2022 and MercedesAMGF1, namely Hamilton, doesn't look so dominant....even Russell outscored Hamilton in points for 2022 in his 1st year with MercedesAMGF1.

@SpadajSpadaj Рік тому
Octane rating of the fuel has no direct link to fuel energy density. It just means that it ignites harder therefore you can compress the fuel-air mix more which translates to the ability of burning more fuel per engine stroke. In fact often high-octane fuels have lower specific energy density than lower-octane ones.

My understanding is that the 1980's "turbo era" engines were the most powerful. Safety concerns for the spectators as well as the drivers caused the rules to change intended to slow down the cars. The whole idea of "formula racing" is to put strict parameters on the racing class and see who makes the best use of them. The more recent change to hybrid engines and reduced fuel load is largely a PR move to make Formula 1 appear to be advancing fuel efficiency and technology that would be pertinent to passenger cars.

There have been more powerful engines by pure power yes. But over a race distance the turbo-hybrid ones are 100% the best. The older engines had 0 reliability.

Those were the times where they sometimes went through a whole engine for a single qualyfing stint.

They are not 1000HP engines. They are 1000HP Power Units. About 150HP is from the batteries. So the engines are more like 850HP. Still a lot in such a lightweight car.

If the remote chamber increases Fuel Efficiency, does anyone know why it's not used on road cars? Presumably it has too high HC emissions?

A full 6 minutes into an 8-minute video, before any real info was talked about in this video 🤔
@azaz911c Рік тому
F1 should have no rules on the size or configuration of the power unit. Let teams self optimize to produce the most competitive car.
@MV1-OP81-Mclaren Рік тому
Please do a video on F1 potentially using inline 4 cylinder engines like the Japan Super Formula are using.
@waynec3563 Рік тому
That was the plan for 2013 (delayed to 2014) originally. The new engines for 2026 will be 1.6L V6s with ~530hp, instead of ~800hp, plus 470hp MGUKs.

Wtf is this 6:20 minutes and a sponsor spot before you actually talk about the pre combustion chamber the topic matter in your video tittle.
@jamsbong Рік тому
With many government pushing for banning of combustion engines, we probably will not see this tech on normal road cars. Right now, the closest F1 like engine you can buy is in the Maserati MC and AMG Project One. Nothing that a common man can afford is available.

It's not a secret, not even really special. Well over a generation ago the tiny BWM engine made 40% more power in quali trim, w/o electric help. Forced induction a hellofa thing. The engines 15-20 years ago that made insane power for their size were special. Certainly not as advanced but 4+hp per cubic inch NA is crazy, esp decades ago.

I don't care how these PUs sound, they are so technologically advanced and efficient that they are my favorite F1 regulation. The people who moan so much about them are just too ignorant about how they work, or are too stupid to care
@sourabh9589 Рік тому
Dude you just tweaked same single contextual meaning with huge lengthened video. Keep it simple and clean. And admit if any ambiguities.

TJI a new technology that back in the early '70's Honda called CVCC.

how does a chamber with tiny holes get the fresh air once it has ignated? that part i miss
@jfess1911 Рік тому
The drawing shown at 6:18 shows an "auxiliary intake port" that supplies air to the chamber.
@adan507 Рік тому
@@jfess1911 powered by the same camshaft I guess. Nice catch, thx!
@jfess1911 Рік тому
@@adan507 Some engines might use a little valve like the old CVCC did, but it would not surprise me if others used a solenoid valve or a compressed air injector. They might need extra air pressure to flush out combustion residue in the short amount of time available. The diagram in this video is the first one I have seen that even mentions an air intake port.
@pranc236 Рік тому
Lean fuel ratio makes more power period. Detonation is the problem you have with being too lean. You say merc figured out the pre chamber but left out their oil burning which was their real advantage.
@DjDolHaus86 Рік тому
Running lean also produces way more heat which is problematic for cars where adding cooling capacity has a massive effect on aerodynamic efficiency. Oil burning was something that Ferrari leaned more heavily on in terms of performance along with using the oil to carry octane boosters and other additives that were banned from being added to the fuel (not saying that mercedes weren't also doing it because everyone was, however Ferrari continuing to try after it was cracked down on suggests more reliance on those additives)
@pranc236 Рік тому
@@DjDolHaus86 and heat is energy. 2nd law of thermodynamics. My point Merc seemed to be able to turn it off and on which points to a injector system of some sort. Merc had blue smoke coming out of the car while setting fastest laps. Commentators even said things about on live broadcast.

Please quickly elaborate or link me to the oil burning concept please. :)
