ACERT Technology

The Cat® C15 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 Cat 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.

C15 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 C15 ACERT engine has a cross-flow cylinder head with refined port geometry, which provides improved breathing and 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.

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 C15 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 air flow 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 engine response.

Electronic Transmission

The Caterpillar seven-speed electronically controlled transmission is designed specifically for the articulated truck and its applications. It features anti-hunt shift shift strategy for speed continuity. It also incorporates Individual Clutch Modulation (ICM) to ensure constant shift times even when the oil is cold.

Two Reverse Gears

The transmission arrangement provides a second reverse gear for improved performance when operating in longer rear hauling applications. First gear reverse is now of a lower ratio for increased rimpull on wet or steep grades.

Controlled Throttle Shifting (CTS)

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

Caterpillar Engine Compression Brake

Provides extra braking effort on downhill grades. It is an excellent match for the C15 ACERT engine, turning it into a power absorbing air compressor. It has very fast response time and produces no additional heat, so it can be used continuously.

Usable Rimpull

Power train components work 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, the engine compression brake works like a brake by slowing the machine.

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.

Front Suspension

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

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

The traction control system 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 at 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.

Enclosed, Oil-Cooled Brakes

Multi-plate, oil-immersed brakes are fitted to both front and center axles. These brakes provide outstanding stopping capability, while maintaining maximum durability and low wear characteristics.

Exhaust Heat System

The body comes exhaust heat ready.

Load-Carrying Capacity
