Je ne m'endors pasBonne nuit !
Pas facile à suivre avec un QI de 8517 minutes de mologue en plan fixe sur sa face ?
@mucha Il est que 20h30 mais je vais me coucher aussi
Même avec un QI de 145 c'est pas facilePas facile à suivre avec un QI de 85

Euh... T'as vu la vidéo ou quoi ?Qui a un QI de 85 ?
Le gars dans la vidéo affirme que ce sont les mâles maghrébins qui sont déficients, alors que les femelles de la même espèce sont très brillantesQui a un QI de 85 ?

Dans la vidéo il dit que les maghrebins ont un QI de 85, les européens de 100 et les asiatiques de 106 en moyenneQui a un QI de 85 ?

Je me demande quel est le sien de QI pour dire des truc aussi débile
non, c'est ça qui est délirant !Il donne des sources ? Des stats ?
Il explique ce qu'est un QI, comment il se calcule, comment il évolue, et en fonction de quoi ?
Non mais il laisse son n° de téléphone à la fin, t'auras qu'à l'appeler pour lui demanderIl donne des sources ? Des stats ?

Non toi c'est ta tension qui est à 14,7 tu confonds toutet moi 147 ..

Air/Fuel Ratio
tuning:Rich vs Lean Why lean makes more power but is dangerous
When discussing engine tuning the 'Air/Fuel Ratio' (AFR) is one of the main topics. Proper AFR calibration is critical to performance and durability of the engine and it's components. The AFR defines the ratio of the amount of air consumed by the engine compared to the amount of fuel.
A 'Stoichiometric' AFR has the correct amount of air and fuel to produce a chemically complete combustion event. For gasoline engines, the stoichiometric, A/F ratio is 14.7:1, which means 14.7 parts of air to one part of fuel. The stoichiometric AFR depends on fuel type-- for alcohol it is 6.4:1 and 14.5:1 for diesel.
So what is meant by a rich or lean AFR? A lower AFR number contains less air than the 14.7:1 stoichiometric AFR, therefore it is a richer mixture. Conversely, a higher AFR number contains more air and therefore it is a leaner mixture.
For Example:
15.0:1 = Lean
14.7:1 = Stoichiometric
13.0:1 = Rich
Leaner AFR results in higher temperatures as the mixture is combusted. Generally, normally-aspirated spark-ignition (SI) gasoline engines produce maximum power just slightly rich of stoichiometric. However, in practice it is kept between 12:1 and 13:1 in order to keep exhaust gas temperatures in check and to account for variances in fuel quality. This is a realistic full-load AFR on a normally-aspirated engine but can be dangerously lean with a highly-boosted engine.
Let's take a closer look. As the air-fuel mixture is ignited by the spark plug, a flame front propagates from the spark plug. The now-burning mixture raises the cylinder pressure and temperature, peaking at some point in the combustion process.
The turbocharger increases the density of the air resulting in a denser mixture. The denser mixture raises the peak cylinder pressure, therefore increasing the probability of knock. As the AFR is leaned out, the temperature of the burning gases increases, which also increases the probability of knock. This is why it is imperative to run richer AFR on a boosted engine at full load. Doing so will reduce the likelihood of knock, and will also keep temperatures under control.
There are actually three ways to reduce the probability of knock at full load on a turbocharged engine: reduce boost, adjust the AFR to richer mixture, and retard ignition timing. These three parameters need to be optimized together to yield the highest reliable power.

Attention, vous allez halluciner un bon coup
@Lilyla , notre ami n'a pas pris ses cachets!!
Il a prier des coures avec les profe Jean-Claude Vandamme ?Attention, vous allez halluciner un bon coup
Non.
J'ai autre chose à foutre
C'est ce que voulait dire mon intervention lol
Salam video,Attention, vous allez halluciner un bon coup
Après lecture de ton post sur l'orthographe je sais que tu ne m'en voudras pas, elle pique un peu les yeux celle ci, d'autant que tu la fais systématiquement :--) désolé :-(Vieux racisme colonial........ la seule chose sur laquelle il base son argumentaire de vérifiable est le QI, qui ne mesure pas l'intelligence donc ça tombe à l'eau. Je ne vois pas comment il justifie islamiquement la délinquance dans les quartiers noirs chrétiens des Etats-Unis, juive dans les colonies palestiniennes, latino dans les quartiers d'Espagne etc etc. Ce mec est consommé par la haine et ça se voit sur son visage, et au lieu de voir ce qui ne va pas chez lui, il va chercher des causes rationnelles avec des démonstrations pseudo intello.... tout est démontable parce qu'il a été chercher ce qu'il voulait pour se conforter dans ses opinions... Flippantes les réactions et le nombre de vues! Commentaire préféré du peu que j'ai lu: "la circoncision, surtout à l'âge de 7 ans est un facteur agravant de violence parce que l'enfant est conscient à cet âge là ce qui explique l'agressivité dans les pays du moyen orient!" Wouaaaaaw :O
