L’id\u00e9e d\u00e9velopp\u00e9e par Cargine Engineering<\/a> est de r\u00e9duire les pertes par frottement en cr\u00e9ant un syst\u00e8me pneumatique destin\u00e9 \u00e0 remplacer le syst\u00e8me de cames mis en place actuellement. Pour ceux qui l’ignorent, les cames (mont\u00e9es sur l’arbre \u00e0 cames) commandent l’ouverture et la fermeture des soupapes. L’arbre \u00e0 cames est directement li\u00e9 \u00e0 l’arbre moteur et donc les possibilit\u00e9s de r\u00e9glages fin pour l’ouverture et la fermeture des soupapes sont r\u00e9duites. <\/p>\n<\/p>\n
<\/p>\n
Avec ce nouveau syst\u00e8me donc, outre un contr\u00f4le accru sur l’admission et l’\u00e9chappement gr\u00e2ce \u00e0 une meilleure r\u00e9gulation de l’ouverture et la fermeture des soupapes, on r\u00e9duit le poids et l’encombrement du syst\u00e8me.

Ce syst\u00e8me semble ne pr\u00e9senter que des avantages (poids, encombrement et consommation r\u00e9duits) mais ils ne parlent pas de la dur\u00e9e de vie et la fiabilit\u00e9 de la technologie, ni m\u00eame du prix de cette derni\u00e8re.<\/p>\n
Le moteur sans came n’est pas nouveau, la nouveaut\u00e9 vient ici du fait que le syst\u00e8me de remplacement soit pneumatique alors que ceux utilis\u00e9s actuellement sur les moteurs sans came sont \u00e9lectromagn\u00e9tiques.
\nQuoiqu’il en soit, si le syst\u00e8me est plus efficace, on devrait le voir bient\u00f4t se g\u00e9n\u00e9raliser et prendre le pas sur l’\u00e9lectromagn\u00e9tique.<\/p>\n","protected":false},"excerpt":{"rendered":"
