The D6T features a Cat C9.3 ACERT™ engine and a Cat Clean Emissions Module to deliver the performance and efficiency that customers demand, while meeting U.S. EPA Tier 4 Interim/EU Stage IIIB emission standards.
Cat NOx Reduction SystemThe Cat NOx Reduction System captures and cools a small quantity of exhaust gas, then routes it into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.
Aftertreatment TechnologiesA Diesel Oxidation Catalyst (DOC) uses a chemical process to convert regulated emissions in the exhaust system. The Diesel Particulate Filter (DPF) traps particulate matter that is carried into the exhaust stream. System components are contained in the Cat Clean Emissions Module (CEM) to protect components, minimize the aftertreatment footprint and simplify maintenance. In Waste Handlers, the Clean Emissions Module is insulated for protection in high debris applications.
Cat Regeneration SystemThe Cat Regeneration System is designed to work transparently, without any interaction needed from the operator. Under most operating conditions, engine exhaust is hot enough to oxidize soot through passive regeneration.
If supplemental regeneration is needed, the Cat Regeneration System elevates exhaust gas temperatures to burn off soot in the Diesel Particulate Filter (DPF). This process happens automatically, but the operator can initiate the cycle when convenient or interrupt regeneration as needed. A soot level monitor and regeneration indicator lights are integrated into the dash display.
Key Off Regeneration – Optional Key Off Regeneration allows the operator to initiate a regeneration cycle after the key has been turned off. If a cycle takes place, the engine will complete regeneration, followed by a cool down period prior to shutting down.
Delayed Engine Shutdown – Delayed Engine Shutdown feature is available to allow the machine to cool immediately after a heavy work load or regeneration cycle.
Engine Idle Shutdown Timer – An optional Engine Idle Shutdown timer will sound a warning and shut down the engine after the machine has been idling for a pre-set period of time.
Engine and Emissions Technology
The power shift transmission and differential steering work with the C9.3 ACERT engine to deliver the outstanding power, productive performance and reliability expected from Cat Track-Type Tractors.
Differential steering maintains full power to both tracks to provide best-in-class turning with a loaded blade. When one track speeds up, the other slows down an equal amount. Maneuverability – especially with large blade loads – is improved, as well as cycle times in some applications. Greater load capacity, power and speed control are possible in soft underfoot conditions on steep slopes.
Exclusive Multi Velocity Program machine control system allows the operator to choose from five speed ranges in Forward and Reverse to best match machine speed to applications and ground conditions. Operators maximize production, minimize fuel consumption, and reduce overall machine operating costs.
Standard Eco Reverse feature reduces engine speed during the reverse portion of the dozing cycle. Once set, no additional operator input is needed. Eco Reverse can reduce fuel use by up to 5 percent, depending on the application.
The engine radiator, Air To Air After Cooler (ATAAC), and hydraulic oil cooler are packaged in a single plane. Aluminum bar plate construction provides durability and allows for higher heat transfer and superior corrosion resistance. The standard cores feature six fins per inch to allow debris to pass through and reduce plugging concerns.
In cooler conditions, a hydraulically driven demand fan reduces speed to conserve power, save fuel and decrease sound levels.
An automatic reversing fan changes the fan rotation while the machine is backing up or stationary. This feature includes access slots in the side of the radiator guard for cleaning access. Roof-mounted air conditioning removes the condenser unit from under the hood. This helps reduce heat load, improves cleaning access and increases ambient capability.
