Hydraulic Fan. The remote-mountedhydraulic fan is temperature sensitive providing variable speeds when needed, which minimizes power requirements. The result is more power to the ground and faster cycle times. Usable Rimpull. Power train componentswork together to offer more usable rimpull at higher speeds on effective grades. In first gear, the torque converter overcomes grade resistance by sending more torque to the wheels and preventing engine lugging. On downhill grades, theretarder acts like a brake by slowing the machine. Retarder. Integral retarder with ahighpower density design. Due to its compact size, the unit quickly fills with oil, providing more retarding power andfast response times. Directional Shift Management. Regulates engine speed during directional shifts to prevent damage caused by high-speed directional changes. Programmable Top Gear Selection. Electronic Transmission Control lets you electronically limit top gear selection without the use of additional service tooling or mechanical limiting of theshift cane. Engine Overspeed Inhibitor. ElectronicTransmission Control (ETC) protects against engine overspeeding by shifting the transmission up one gear at specified rpm settings. If the transmission is in its highest gear, torque converter lockup disengages. Electronic Clutch Pressure Control. Controlled Throttle Shifting (CTS). Electronic Transmission. ECPC technology works with Controlled Throttle Shifting to manage shift torque and provide exceptional shift smoothness. Significantly reduces power train stress and clutch wear by controlling engine speed, torque converter lock up and transmission clutch engagements. The Caterpillarsix-speed electronically controlled transmission is designed specifically for the articulated truck and its applications. It features anti-hunt shift strategy for speed continuity. Wastegate Turbocharging. Singlewastegate turbocharger provides higher boost over a wide range, outstanding low-end performance with improved peak torque and enhanced engine response. Air-to-Air Aftercooling (ATAAC). ATAAC keeps air intake temperatures down and, in concert with the tight tolerance combustion chamber components, maximizes fuel efficiency and minimizes emissions. Significant improvements in airflow are generated by a turbocharger, unique cross-flow head and a single overhead camshaft.

Articulated Truck - 19427 Performance and Productivity – Power Train

Integrated power train with more power, greater performance and lower fuel consumption –the power to do more work.

Mechanically Actuated ElectronicUnitInjection (MEUI). A highly evolvedfuelsystem with a proven record of reliability in the field. It combines the technical advancement of an electronic control system with the simplicity ofdirect mechanically controlled unit fuelinjection. It excels in its ability tocontrol injection pressure over the entire engine operating speed range. These features allow the Cat C11 to have complete control over injection timing, duration and pressure.
