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.

Fascinant mais je ne parle pas très bien l'espagnol :-/
 
Le mélange air-carburant idéal ou mélange stoechiométriqueLe rapport idéal d'air et de carburant d'un moteur essence est de 14,7 kg (12,250 L) d'air pour 1 kg (1,33 L) de carburant.Un mélange air/essence idéal de 1kg de carburant pour 14,7 kg d’air aussi appelé mélange "stoechiométrique" génère une combustion homogène et complète non polluante.
Dans l’industrie automobile, ce rapport air-carburant est représenté par la lettre grecque lambda (λ). Le rapport est idéal lorsque λ = 1. Il garantit un fonctionnement optimum du catalyseur qui convertit les rejets nocifs en gaz non polluants pour l‘environnement.
La plupart des moteurs essence fonctionnent avec ce mélange.
Avec un autre carburant, le dosage air/carburant peut être différent.

Attention, vous allez halluciner un bon coup :D


Effectivement hallucinant, ce crétin semble ignorer par exemple que les Marocains figurent parmi les étudiants les plus présents dans les écoles parisiennes d'ingénieurs, il confond l'origine ethnique et sociale...Tu sais mec (je m'adresse au type de la vidéo, breton à deux balles), les franchouillards "de souche" ont aussi leurs glandeurs, leurs racailles, leurs beaufs, et ça ne brille franchement pas des masses
 
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

Pour finir un peu avec une note drôle, ça aurait pu marcher si on avait fait venir que les femmes maghrébines
MDR

D’où tu ponds tes statistiques ?
Tu le sais pas peut être mais c'est interdit en France les statistiques ethniques
J'ai regardé ta vidéo et je conclus que tu as peur du frère de ta copine tunisienne, bon bref
Admettons que nous sommes pas intelligents dans ce cas explique moi monsieur le génie comment se fait-il que les maghrébins ont conquis l’Espagne et la France jusqu'à Poitiers

Conclusion: Certains hommes occidentaux pensent que les ressources des autres leurs appartiennent y compris les femmes

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 :-(
