ACERT Technology. The Cat C11 ACERT engine introduces a series of evolutionary, incremental improvements that provide breakthrough engine technology built on systems and components developed by Caterpillar with proven reliability. The technology capitalizes on Caterpillar expertise in four core engine systems: fuel, air, electronics and after treatment. ACERT technology is a unique and revolutionary systems solution that enables Cat engines to meet today’s clean air regulations, thus establishing the building blocks for attaining tomorrow’s more stringent standards.

C11 Block. The one-piece, gray iron block features generous ribbing for stiffness and heavy bearing bulkheads for rigidity and strength as the crankshaft turns. Straight O-ring connection points reduce the loss of engine oil and fluids.

Cylinder Head and Piston Technology.

The C11 has a cross-flow cylinder head with refined port geometry, which improves breathing and provides better combustion. The Monotherm/steel pistons have a forged steel design, which offers high strength, light weight and tighter tolerances. The result is better oil control, minimal blow-by and long liner life.

Advanced Diesel Engine Management (ADEM) A4 Engine Controller.

The ADEM A4 electronic control module manages fuel delivery to get the best performance per liter or gallon of fuel used. The engine management system provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. It tracks engine and machine conditions while keeping the engine operating at peak efficiency.

Fuel Delivery. Multiple injection fuel delivery involves a high degree of precision. Precisely shaping the combustion cycle lowers combustion chamber temperatures, generating fewer emissions and optimizing fuel combustion. This translates into more work output for your fuel cost.

Noise Reduction Technologies.

Noise reduction has been achieved through design changes to the isolated top cover, oil pan, multiple injection strategy, insulated timing case cover, sculpted crankcase and gear train refinements.

Cat C11 Engine with ACERT Technology

A combination of proven systems and innovative new technologies, ACERT engines optimize performance while meeting EPA Tier 3 and EU Stage 3a engine exhaust emission regulations.

Mechanically Actuated Electronic Unit Injection (MEUI). A highly evolved

fuel system with a proven record of reliability in the field. It combines the technical advancement of an electronic control system with the simplicity of direct mechanically controlled unit fuel injection. It excels in its ability to control injection pressure over the entire engine operating speed range. These features allow the C11 to have complete control over injection timing, duration and pressure.

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.

Wastegate Turbocharging. Single wastegate turbocharger provides higher boost over a wide range, outstanding low-end performance with improved peak torque and enhanced engine response.

Electronic Transmission. The Caterpillar six-speed electronically controlled transmission is designed specifically for the articulated truck and its applications. It features anti-hunt shift strategy for speed continuity.

Electronic Clutch Pressure Control.

ECPC technology works with the Controlled Throttle Shifting to manage shift torque and provide exceptional shift smoothness.

Controlled Throttle Shifting (CTS).

Significantly reduces power train stress and clutch wear by controlling engine speed, torque converter lock-up and transmission clutch engagements.

Engine Overspeed Inhibitor. Electronic Transmission 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.

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 the shift cane.

Retarder. Integral retarder with high-power density design. Due to its compact size, the unit quickly fills with oil, providing more retarding power and fast response times.

Retarder Power. Increased power capability gives operators greater control on short, steep grades and minimizes the need to apply the brakes, resulting in extended service brake life.

Hydraulic Fan. The remote-mounted hydraulic 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.

Performance and Productivity – Power Train

Integrated power train with more power, greater performance and lower fuel consumption.

Front Suspension. Three-point front suspension oscillates ±6° to provide a smooth ride, allowing the 730 to travel at speed over rough terrain and softening impact loads on structures and components.

A-Frame Construction. The front suspension uses an oscillating A-frame with a lateral tie rod to control axle sideways movement.

Front Suspension Cylinders. Large bore, low pressure cylinders are purpose designed for tough applications and offer a soft, smooth ride.

Mounting Points. Suspension mounting points are integrated into the axle housing, increasing reliability.

Rear Suspension. Features a walking beam geometry with Caterpillar designed rear suspension mounts which provide a reliable and stable ride for excellent load retention.

Traction Control. Traction control is comprised of a wet clutched inter-axle differential and wet clutched cross-axle differentials. All differentials can be engaged and disengaged on-the-go for maximum versatility. When used together, the differentials provide 100 percent driveline locking.

Inter-axle Differential Lock. Locks all three axles in unison and modifies torque distribution for excellent traction in poor underfoot conditions and on grades. It is operated by a switch located in the footrest.

Cross-axle Differential Locks.

Provides full driveline locking – all three axles and all six wheels for maximum performance in the most adverse conditions. Acts in unison with the inter-axle differential lock when the footswitch is actuated and the dash-mounted switch is selected.

Fast Hoist Cycle Times. Fast body raise and lower times mean less time spent in the dump area.

Load-Carrying Capacity. Large target area provides high-load carrying capacity. Its diverging flow design gives clean load ejection, which maximizes production and avoids waste of material carry-back.

Exhaust Heat System. The body comes exhaust heat ready.

Steering System. Cat articulated trucks use a load-sensing steering system for smooth, precise control. It features a single, variable displacement pump. Two double-acting, cushioned steer cylinders allow the machine to articulate 45° to the left or right, permitting precise positioning in tight areas. Its compact Hand Metering Unit controls the cylinder for responsive steering and performance. An electronic secondary steering system is standard.

Hydraulic Steering Cushioning System.

The 730 incorporates a hydraulic cushioning system, resulting in smooth, responsive steering, operator comfort and reduced shock loads to the machine components.
