Corps principal<\/p>\n
1.1 Définition et Rôle<\/p>\n
Un capteur de position d'arbre à cames est un dispositif électronique qui détecte la position angulaire et la vitesse de l'arbre à cames du moteur, puis transmet ces informations à l'unité de contrôle du moteur (ECU). L'ECU utilise les données de position de l'arbre à cames pour ajuster l'allumage, l'injection de carburant, le régime de ralenti et les fonctions liées aux émissions. Les capteurs de position d'arbre à cames de qualité exportation sont des dispositifs de rechange ou de remplacement qui répondent ou dépassent les exigences d'origine en termes de robustesse, de durabilité et de précision. Ils sont soumis à des tolérances plus strictes, à une validation de fiabilité plus poussée et à des restrictions de matériaux plus rigoureuses que les produits de rechange standard.<\/p>\n

Labeling and Documentation <\/span><\/p>\n Labels affixed to each carton should have: <\/span><\/p>\n ¡ñPart number, batch code, and quantity. <\/span><\/p>\n ¡ñHandling instructions like ¡°Fragile¡± or ¡°This Side Up.¡±<\/span><\/p>\n ¡ñCompliance marks as needed (CE, EAC, etc. ). <\/span><\/p>\n The following documents should be packaged with each carton:<\/span><\/p>\n ¡ñCommercial invoice. <\/span><\/p>\n ¡ñPacking list. <\/span><\/p>\n ¡ñCertificate of origin. <\/span><\/p>\n 5.3 Shipping Modes and Consolidation <\/span><\/p>\n Transport mode decision should consider: <\/span><\/p>\n ¡ñOcean freight if shipping large volumes and cost is the priority.<\/span><\/p>\n ¡ñAir freight if speed of replenishment is essential (trade-off between cost and lead time).<\/span><\/p>\n ¡ñRail + truck (multimodal) where transport infrastructure supports these options.<\/span><\/p>\n Shipping multiple customer orders together to full-container load (FCL) can lower freight costs per
