réduit les charges d'exploitation et diminue les émissions polluantes
il continue à proposer des fonctions haut de gamme, notamment la direction différentielle, qui offre un braquage variable à l'infini tout en fournissant une puissance maximale aux deux chaînes, ou encore le train de roulement suspendu, qui garantit une traction optimale sur les terrains irréguliers. Le système Auto Shift avancé, qui diminue la consommation de carburant
de 6 % pour certaines applications, fait partie des nouvelles fonctionnalités complémentaires qui augmentent les performances et réduisent les coûts.
Ce procédé réduit la température des cylindres et, par conséquent, diminue la formation d'oxyde d'azote. Le module CEM, une unité de post-traitement compacte, contient un catalyseur d'oxydation diesel et un filtre à particules diesel.
Height of the solid, proven design of its predecessors, the new tractor chains D8T Caterpillar offers new features that increase efficiency and productivity while reducing operating expenses. The model uses the D8T Cat C15 ACERT ™ engine, a net power rating of 231 kilowatts. This engine uses ACERT technology, including the system of reducing nitrogen oxides Cat and Cat Clean Emissions Module, in order to comply with EU Stage IIIB emissions standards.
The new model D8T is renowned for its quality and exceptional performance; it continues to deliver high-end features, including differential steering, which offers an infinitely variable steering while providing maximum power with two channels, or the suspended undercarriage, which guarantees maximum traction on land irregular. Advanced Auto Shift system, which reduces fuel consumption 6% for some applications, is part of the new additional features that increase performance and reduce costs.
The new cooling system includes a one-piece radiator, hydraulic oil cooler and a cooler inlet air to air that are installed on a single plane to facilitate maintenance. The air conditioning condenser mounted on the ROPS in addition to the new cooling system is protected for applications that generate a lot of debris.
Service points at ground level provide access to the battery switch and engine stop switch, but also with optional lighting contactors, without mounting on the machine. The new sets of lights, steps and handrails make entry and exit of the machine.
The new cabin interior is easier to clean, while the rationalization and harmonization of instruments and displays the dashboard on the full range of tractors enhance operator efficiency. Technological strengths With integrated beam incorporated in the machine during assembly, the model is pre-equipped D8T for controlling leveling. This facilitates the pre-equipment dealer installation of a control system and AccuGrade ™ guide to buying the machine, or later if changing needs of the operator.
The model also offers the new D8T Grade Control Cat optional. This system of control and guidance of the machine factory installed guide the blade along the terrain and enhances the overall productivity of the machine with features such as function AutoCarry ™, automatic control of the ripper, the blade support Automated grading and protection. The system mounted on the frame moves the traditional technology for positioning the edge of the blade at the top of the cabin. This innovative design reduces damage to the receiver, to improve visibility for the driver and remove the receiver / antenna, masts and cables.
The model also offers D8T * Cat Product Link, which tracks the remote equipment to increase the overall efficiency of park management. Product Link is integrated systems of the machine. Events and diagnostic codes, but also the hours, fuel, downtime, etc.. are transmitted to a secure Web application, VisionLink. VisionLink uses powerful tools to relay information to users and dealers, including mapping, operation, idle time, fuel level, etc..
Emissions ACERT Technology combines an innovative management of the intake air, which operates an optimized turbocharger, an electronically controlled injection, which regulates precisely each combustion cycle through multiple fuel injections. This careful control of combustion parameters ensures extremely clean combustion, stable power regardless of the operating conditions and outstanding fuel efficiency.
The system for reducing nitrogen oxides and Cat deviates continuously cools a small volume of exhaust gases from engine then injects the cooled gases in the combustion chamber. This process reduces the temperature of the rolls and, consequently, reduces the formation of nitrogen oxide. The EMC module, a unit of compact after-treatment, contains a diesel oxidation catalyst and a diesel particulate filter.
The diesel particulate filter (DPF) removes particles from exhaust gases. Its design ensures the driver a minimum of maintenance and attention. In most situations, the exhaust of the engine is hot enough to oxidize the soot within the filter by the bais of a process of passive regeneration. However, if a further regeneration is required, the Cat Regeneration System increases the temperature of exhaust gas to oxidize the soot particles within the DPF. The Cat Regeneration System is designed to work seamlessly: it turns on automatically without the driver and performs the regeneration when the conditions are optimal.
The model proposes D8T regeneration ignition off option, and an engine shut-off timer and a timer cut engine idling. For applications that generate a lot of debris that require the installation of heat shields on exhaust components, an isolated EMC is optional.
