Appolo Tank

[Guest]

Bonjour,

quelqu'un peut-il m'expliquer le principe de l'appolo tank, histoire de parfaire ma culture générale <!--emo&-->[img]http://www.forum-autoroule.com/html/emoticons/vert.gif' border='0' style='vertical-align:middle' alt='vert.gif' /><!--endemo--> <!--emo&-->[img]http://www.forum-autoroule.com/html/emoticons/vert.gif' border='0' style='vertical-align:middle' alt='vert.gif' /><!--endemo--> <!--emo&-->[img]http://www.forum-autoroule.com/html/emoticons/vert.gif' border='0' style='vertical-align:middle' alt='vert.gif' /><!--endemo-->

Ou me donner une solution à mon problème technique :

j'ai un moteur de sierra cosworth ( oui, je sais encore un qui confond puissance et poids), mais pas 500CV, pas la motivation <!--emo&-->[img]http://www.forum-autoroule.com/html/emoticons/sleep2.gif' border='0' style='vertical-align:middle' alt='sleep2.gif' /><!--endemo--> <!--emo&-->[img]http://www.forum-autoroule.com/html/emoticons/sleep2.gif' border='0' style='vertical-align:middle' alt='sleep2.gif' /><!--endemo--> <!--emo&-->[img]http://www.forum-autoroule.com/html/emoticons/sleep2.gif' border='0' style='vertical-align:middle' alt='sleep2.gif' /><!--endemo-->
Le carter raboté a perdu 1 litre et je trouve cela un peu embettant, vu le prix du moulin ..........
Donc, j'ai rajouté un radiateur d'huile ( Air Huile) et une réserve tampon ( tube tout bête), mais plus assez de pression d'huile <!--emo&-->[img]http://www.forum-autoroule.com/html/emoticons/cry.gif' border='0' style='vertical-align:middle' alt='cry.gif' /><!--endemo--> <!--emo&-->[img]http://www.forum-autoroule.com/html/emoticons/cry.gif' border='0' style='vertical-align:middle' alt='cry.gif' /><!--endemo--> <!--emo&-->[img]http://www.forum-autoroule.com/html/emoticons/cry.gif' border='0' style='vertical-align:middle' alt='cry.gif' /><!--endemo-->
2.8b à froid ( correct), mais plus que 1 bar à chaud au lieu de 1.8 recommandé.
Donc, mes culbuteurs claquent à chaud, pas à froid, ce qui est l'inverse de l'habitude

Sur ce moteur, il y a déja un modin (echangeur Huile/eau) au niveau du filtre à huile

Donc, tout ces accessoires génèrent une perte de charge significative .........

d'ou mon idée de monté un appolo tank, mais je ne connais pas son utilité et son principe de fonctionnement

si vous avez une solution <!--emo&-->[img]http://www.forum-autoroule.com/html/emoticons/bien.gif' border='0' style='vertical-align:middle' alt='bien.gif' /><!--endemo--> <!--emo&-->[img]http://www.forum-autoroule.com/html/emoticons/bien.gif' border='0' style='vertical-align:middle' alt='bien.gif' /><!--endemo--> <!--emo&-->[img]http://www.forum-autoroule.com/html/emoticons/bien.gif' border='0' style='vertical-align:middle' alt='bien.gif' /><!--endemo-->

ENGINE UPGRADES

INTRODUCTION
Like many other upgrade paths available to the Seven owner, there are several ways you can go about upgrading your engine - but getting it right is important. Is the car going to be used on track a lot? If so, then improving longevity and building in resistance to the rigours of high rpm will be money well spent before wringing out a few more horses.

With the K-series being common to a number of cars, including its original Rover and MG applications, there are many third party companies that can offer upgrade parts. Choosing a Caterham engine upgrade gives you the reassurance of quality and the output claims. With many of our conversions being options on new cars, it has been essential for us to develop them for reliability and longevity, as well as performance, in partnership with MG-Rover and race engine specialist, Minister Power. This has enabled us to offer a range of proven upgrades that carry Caterham warranty and piece of mind of being 'factory standard'. As such, Caterham engine upgrades will generally enhance the value of the car.


IDENTIFYING YOUR ENGINE

Assuming that you know the capacity and basic specification of your engine, the only other key detail required before embarking on an upgrade is whether it is EU2 or EU3 (merely an emissions level). The EU2 engine has a roughly symmetrical cam ribbed cover, with a central insert over the spark plugs. Standard EU2 engines were in production into 2001 and continue today in a modified form in the R3/4/500 cars. In contrast the EU3 cam cover is asymmetrical with a large plastic coil cover over 2/3 of the metal cam cover. EU3 engines were introduced in 2001.

Anti-Cavitation 'Apollo' Tank

An option on all models (with a special version for the dry-sumped R400 and R500), the anti-cav or Apollo tank is a de-aeration system. Under track conditions, high cornering 'g' and high rpm give the oil a good thrashing. This can lead to air becoming trapped in the oil, reducing its lubrication properties and in turn potentially producing oil starvation problems. With the anti-cav system, oil is centrifuged as it passes through the Apollo tank. This forces the air from the oil, which is then bled into the top of the rocker cover. This system is recommended for all cars that are to be used for track days, especially VVC models. Many owners also like the additional oil capacity that this provides to the system. The Apollo tank system is standard on all Caterham race cars as a minimum and provides reliable protection for all cars fitted with treaded tyres.
