CASE C Series excavators use clean and efficient Tier 4 interim diesel engines. Equipped with cooled exhaust gas recirculation (CEGR) and a diesel particulate filter, the engine is capable of meeting emissions regulations without the need for additional diesel exhaust fluids.
Automatic self-regeneration of the diesel particulate diffusor (DPD) ensures no loss of productivity, while low engine rpm, improved hydraulic pump control and five new energy saving systems boost fuel economy by up to 10%. A green economy gauge can be activated in the cab to inform the operator of the most economical operating mode setting for the machine, reporting fuel consumption in real-time.
ADVANCED ENERGY MANAGEMENT
Through the use of 5 new fuel saving functions, C series excavators speed up productivity and substantially improve fuel economy. The new systems include:
Boom Economy Control (BEC)
Increased fuel effi ciency during boom lower and swing operations.
Automatic Economy Control (AEC)
Improved fuel effi ciency when servo joysticks are in neutral position and the operator is not calling for power from the machine.
Swing Relief Control (SWC)
Carefully manages the hydraulic power distribution at slewing operations, to provide the most effi cient flow and pressure.
Spool Stroke Control (SSC)
Creates an automatic pressure adjustment during digging and leveling operations. It saves fuel, while improving controllability for the operator in fine digging operations.
Auto Energy Save (AES)
All C-series excavators also feature Auto Idle and Idle Shut Down systems. When activated, Auto Idle automatically lowers engine revs, whatever the throttle position, when the levers have been inactive for 5 seconds. Manually, Idle can be activated by a switch on the joystick. Idle shut down, when activated, shuts down the engine when there has been no activity for 3 minutes, resulting in additional fuel savings.
As part of the CASE Intelligent Hydraulic System all CASE C Series excavators benefit from improvements in performance and productivity.
Lifting capacity is increased and cycle times have been cut. Individual operating weights are slightly increased to cope with the additional digging and loading forces, ensuring stable, consistent high production. Bucket and boom down regeneration systems feed hydraulic oil back to the supply side of the pump, reducing the requirement for engine power. The C Series excavators use the familiar working mode control from the B Series machines, making it easy for the operator to become familiar with the new models. The H and SP Modes provide a 5% boost when required for maximum digging ability.
The new monitor in the C Series machines provides operators with the chance to pre-programme auxiliary hydraulic flow and pressure settings (option) for up to 10 attachments, providing rapid changeover and increased productivity.
