BENEFITS & FEATURES
Powertrain
First-of-its-kind Electric Drive delivers power and efficiency


Powertrain

The electric generator, power inverter and propulsion module in the electric drive system replace traditional mechanical components such as a torque converter and transmission. The Cat C9.3 engine with ACERT Technology turns a powerful electric generator that efficiently converts mechanical energy into AC electrical current. Electrical current from the generator flows through specially armored cables and military grade connectors to a solid-state power inverter. Advanced electronics send AC current to the propulsion module to control the motors and provides DC current for the accessory systems. The propulsion module delivers well-modulated torque via axles to the final drives. Consisting of state-of-the-art AC electric motors - and connected to the D7E updated differential steering system - the propulsion module has no moving electrical contacts and few moving mechanical parts. All electrical components are fully sealed to safely operate in a wide range of dozing conditions. Liquid cooling ensures that the electric drive components deliver peak performance in extreme temperature conditions. The D7E electric drive system is highly efficient at delivering engine power to the ground. Infinitely variable speed control, means there are no gears to shift. Operators can concentrate on the task and the job site, rather than on shifting gears and managing engine speed. Training is simplified as well. A proven differential steering system combines with electric drive to make the D7E the only system that can perform locked-track pivot turns for better maneuverability. A dedicated D8-size steering pump delivers improved performance.

Benefits
  • Fuel efficiency: 10 - 30 percent less fuel burned per hour.
  • Reduced owning and operating costs: Fewer moving parts, longer drive train component life, reduced lifetime service and maintenance.
  • Resourceful: Designed to use less fuel and fluids, and fewer replacement parts.
  • Increased efficiency: Lower fuel usage per cubic yard of material moved.
  • Increased productivity: More material moved per hour.
  • Versatility: Power, smooth operation and maneuverability for a wide variety of applications.

Engine
ACERT™ Technology


Engine

The D7E features a Cat C9.3 ACERT engine and a Cat Clean Emissions Module aftertreatment to deliver the performance and efficiency that customers demand, while meeting U.S. Tier 4 Interim/EU Stage IIIB/Japan MLIT Step 4 emission standards. The efficient drivetrain allows the engine to operate in a tighter rpm range, 1,500 - 1,800 rpm, which helps extend engine life and improve fuel economy. The increased drivetrain efficiency also allows the machine to achieve greater performance at lower horsepower than previous models, adding even more to the D7E overall benefits.

Features
  • Serviceability: Electric priming pump and easier engine access make service easier.
  • Leak Protection: Components are sealed, preventing leaks and protecting fluids from contamination.

Cooling System
Efficient and easy to service


Cooling System

The D7E cooling system uses a three-part radiator built with rugged, highly efficient aluminum bar cores for charged air, jacket water, and the separate circuit. Although the jacket water and separate circuit coolant operate at different temperatures, the radiator appears and acts as one integrated unit. Airflow is managed by a hydraulic variable speed demand fan, reducing power requirements and fuel consumption. A molded shroud ensures efficient air flow through the radiator and the fan utilizes lightweight, durable blades for high efficiency and quiet operation. A larger gap between fins reduces plugging, and the single-plane design allows for easier cleaning and service.

Emissions Technology
Reliable, integrated solutions


Emissions Technology

Cat NOx Reduction System
The 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 Technologies
To meet U.S. Tier 4 Interim/EU Stage IIIB/Japan MLIT Step 4 emission standards, Cat aftertreatment components have been designed to match application needs. System components include a Diesel Oxidation Catalyst (DOC), which uses a chemical process to convert regulated emissions in the exhaust system, and a Diesel Particulate Filter (DPF) that traps particulate matter that is carried into the exhaust stream. The DOC, DPF and Cat Regeneration System are contained in a Caterpillar designed Clean Emissions Module (CEM) that protects the components, minimizes the aftertreatment footprint and simplifies maintenance. For high debris applications that require thermal shields on exhaust components, an optional insulated CEM is available for the D7E.

Cat Regeneration System
The 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 is a process that happens automatically, but the operator can initiate the cycle when convenient or interrupt regeneration as needed. Soot level monitor and regeneration indicator lights are integrated into the dash display.

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.

Operator Station
Unprecedented all-around visibility and comfort


Operator Station

The D7E cab is designed to maximize operator efficiency. From the operator’s seat, the single center post aligns perfectly with the air intake, exhaust and lift cylinder, greatly enhancing forward visibility. The angled door provides more side glass area, enhancing sightlines to the blade and all around the job site. That helps operators work more confidently and productively all shift long and enhances job site safety.
  • The cab offers more interior space, as well as wider, swing out doors for easier cab access.
  • Ergonomic controls are fully adjustable and designed for low-effort comfort. Switches and controls for various systems are located within easy reach of the operator.
  • A standard Eco Reverse mode works during the reverse travel direction of the dozing cycle and during idle time to save even more fuel.
  • Interior noise levels are reduced to a quiet 75 dB(A) (ISO 6396).
  • A single-unit heating, ventilation and air conditioning (HVAC) system is self contained and powered by electrical current from the accessory power converter. It has no belts, needs no long refrigerant lines, and maintains maximum cooling efficiency even when the machine goes to idle.
  • An integrated display screen provides a range of machine status information, plus safety, service and maintenance-related alerts. Built-in connections and mounts make for easy installation of a grade control system display.
  • A speed recall feature allows operators to pre-set the desired forward and reverse travel speed, and then resume that speed simply by pressing a button.
