Cat C15 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 emissionregulations.

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 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.

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 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 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 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 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 Cat 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 effectively slows 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.

Performance and Productivity – Suspension and Traction Control

Suspension systems and traction control – delivering power to the ground in all conditions.

Front Suspension

The three-point front suspension permits the axle to oscillate ±6°, softening impact loads on structures and components and providing a smooth ride, so the operator can travel at speed over rough terrain.

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.

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 cylinders for responsive steering and performance. An electronic secondary steering system is standard.

Enclosed, Oil-Cooled Brakes

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

Performance and Productivity – Ejector

Designed to disperse the load on-the-go for faster cycle times and lower spreading costs.


The 740 Ejector is designed to disperse the load on-the-go for faster cycle times and lower spreading costs. The ejector body also offers clean load ejection and the capability to work in areas with restricted overhead clearance and soft underfoot conditions.


The 740 Ejector is based on the standard 740 Articulated Truck and shares all its versatility. It can operate in the same conditions, yet offers a number of unique capabilities that stretch the operation envelope.


The truck can eject the material and spread it out while moving, reducing the size of additional spreading and dozing equipment. This makes the 740 Ejector an ideal solution for road building and landfill applications. On-the-go ejecting results in faster cycle times and reduced power train loads.


Ejecting the load without raising the body increases stability, allowing load dispersal on inclines, side slopes and in very soft underfoot conditions. Generally, these conditions would be unacceptable with a conventional truck, but are ideal for the 740 Ejector, especially on landfill sites.

Overhead Clearance

Because the body is not raised when ejecting the load, the truck can be utilized in areas with reduced overhead clearance such as when working around overhead lines, conveyors, hoppers and bridges. The ejector is also ideal for tunneling and underground operations.


The design of the ejector is inherently self-cleaning and practically eliminates material sticking to the body, which increases productivity, improves fuel efficiency and lowers cost per ton.


Reinforced body is made from thick high-yield, heat-treated Brinell hardened steel (Brinell 400 on the base and sides) that provides exceptional durability. Ejector top rails are made from high-strength alloy steel. For optimum durability and wear life, the ejector body is designed to work in applications where the material consists of rocks smaller than 152 mm (6 in.) in diameter.


The ejector blade is made from high-strength steel and uses technology similar to that proven in Cat wheel tractor-scrapers.


A four-stage, high-speed, double-acting cylinder is specifically designed for horizontal mounting and provides smooth load ejection. It is centrally supported and nitride-hardened to ensure a long service life.

Proven Technology

Much of the 740 Ejector design is carried over from the Cat 740 Articulated Truck.

Durability and Reliability

High availability leads to high productivity. Excellent durability keeps ownership costs low.

Front Frame

The front frame design features a large box section and wide, stiff frame beams to handle torque loads. The divergent frame design decreases stress in the hitch area and optimizes suspension geometry. The design incorporates advanced technologies such as Finite Element Analysis to optimize the frame before the first machines are ever built.

Rear Frame

Twin-box construction minimizes stress concentrations and provides low weight with long life.


Both front and rear frames make extensive use of heavy-duty steel castings to handle stress concentrations.


Provides unparalleled ride quality and protects the truck from the most adverse road conditions by absorbing shock loads that would otherwise reach the frame.

Articulating/Oscillating Hitch

The articulating hitch provides the truck with steering articulation, and the oscillation ensures all-wheel ground contact in rough terrain.

Steer Cylinders In-Line with Hitch

Steering cylinders are in-line with the hitch, minimizing steer loads and stress in the hitch area.

Hitch Construction

Two-piece bolted hitch features a strong, durable cast steel head bolted to a hardwearing forged steel tube. The hitch tube has hardened bearing areas and a hardened thrust face for reduced maintenance and longer life.

Service Brakes

Oil-cooled, multiple disc brakes are continuously cooled for exceptional non-fading braking. They are designed and built for reliable, adjustment-free operation.

Parking Brake

Located on the center axle in an elevated position and designed to deliver higher heat capacity and abuse resistance.

Cat Power Train Components

All major components have been purpose-designed for earthmoving applications. In fact, many of the major components have been designed specifically for articulated trucks.

Radiator Protection

The radiator is located behind the cab for excellent visibility. This design incorporates three levels of protection:

Operator Comfort

The operator’s office – high productivity from a comfortable, motivated operator.

Ease of Operation

Designed for simple, easy operation, the 740 Ejector allows the operator to focus on production.

Ergonomic Layout

The controls and layout of the cab are designed to make it as easy to operate as your car. Quick, easy to read and simple to operate, the controls and gauges allow the operator to concentrate on production.


The Generation II wrap-around dash puts all controls within easy reach of the operator. Featuring LED illuminated rocker switches, large LCD display and a rear wash wipe rocker switch. It provides an automotive feel with the industrial strength you would expect from Caterpillar.

Viewing Area

The low sloping hood and placement of the cooling package behind the cab give the operator excellent all-around visibility. The large glass area and central operator position also provide excellent visibility.


The wet arm wiper system cleans more glass area and is bottom-mounted to keep it out of the operator’s line of sight. Windows are tinted to reduce glare.

Differential Lock Controls

The inter-axle differential lock is engaged/disengaged by using a raised switch incorporated into the drivers foot rest, for ease of operation. For 100% lock up, all three cross-axle differential locks act in unison with the inter-axle differential lock when the foot switch is activated and a dash mounted switch is selected. Disengaging the foot switch opens all differential locks immediately.

Dash-Mounted Switch

A dash-mounted switch is all that is required to select full driveline lock-up.

Transmission and Ejector Levers

Finger tip controls allow easy operation and low effort. The ejector and transmission levers are positioned for easy, comfortable operation, along with the control for top gear limit, transmission hold and neutral lock.

Blade Retraction Sequence

The ejector blade returns to the loading position as soon as the blade retract sequence is initiated. The transmission is held in the gear selected for the ejecting cycle until this sequence is completed and the ejector control lever is returned to the float position.

Retardation Control

The Cat engine compression brake control lever is positioned on the right-hand side of the steer column. Four modes of operation, with three steps of retardation, provide an optimum match between operating conditions and retarding power.

Suspended Pedals

Easy to operate and reach with plenty of leg and foot room. They also make for easier cleaning of the cab floor by keeping the pedals out of the dirt.

Cat 2S Monitoring System

Provides an improved method of monitoring critical machine functions and alerts the operator to an immediate or impending problem. The system provides four levels of warning:


More time on production, less time and money spent on servicing.

Long Service Intervals

Long engine oil change and hydraulic oil change intervals lower maintenance costs and downtime. Wheel bearing adjustment is completely eliminated.

Lube Points

Lube points are grouped at the rear of the front frame and the front of the rear frame. Universal joints are lubed for life, eliminating servicing. Autolube is optional.

Service Points
