ACERT Technology incorporates a series of innovations working at the point of combustion to optimize engine performance while meeting U.S. EPA Tier 3 engine emission regulations.
Cat C7 Engine with ACERT TechnologyThe C7 engine provides a full-rated gross power (SAE J1995) of 167 kW (224 hp) at 2200 rpm with a torque of 872 N-m. The combination of large displacement and high torque allow the AP-1000D to perform under the toughest conditions.
HEUI Fuel InjectionThe HEUI™ fuel system is unique and combines the technical advancement of an electronic control system with the simplicity of HEUI fuel injection. The HEUI fuel system excels in its ability to control injection pressure over the entire engine operating speed range. These features allow the C7 engine to have complete control over injection timing, duration and pressure.
Multiple Injection Fuel DeliveryMultiple injection fuel delivery involves a high degree of precision. Precisely shaping the combustion cycle lowers combustion chamber temperatures, which generates fewer emissions, optimizes fuel combustion and translates into more work output for your fuel cost.
High Cylinder PressuresHigh cylinder pressures combined with tightly controlled tolerances promote extremely efficient fuel burn, less blow-by and lower emissions.
C7 Cylinder BlockThe C7 engine’s cylinder block offers increased tensile strength. It features improved sealing with gaskets to ensure fewer leaks. This new design supports the engine’s higher compression ratios and increases its power density. The incorporation of straight-thread “O” ring connection points reduce the loss of engine oil and fluids.

Air-to-air aftercooling keeps air intake temperatures down, maximizing fuel efficiency and minimizing emissions.
ADEM™ A4 Electronic Control ModuleThe ADEM A4 electronic control module manages fuel delivery, valve timing and airflow to get the most performance per liter (gallon) of fuel used. The control module provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. The control module also monitors engine and machine conditions while keeping the engine at peak efficiency.
Dual Operator Stations
The dual operator stations provide complete control and good visibility from either side of the operating platform.
Dual Operator StationsThe dual operator stations incorporate fully equipped consoles with adjustable suspension seats, armrests and retractable seat belts.
Operator VisibilityThe dual operator stations can be positioned in one of four different locations to provide optimum visibility. The stations can extend beyond the machine frame for good visibility when joint matching or while paving other applications where precise control is required.
The operator consoles are designed for productivity and accessibility. All gauges and displays are grouped for convenient and simple operation.
Operator ConsolesEach operator’s station includes ground speed indicators, material handling controls, propel controls and screed extender controls. The controls for each station are in the same relative position providing easy control from either console.
Speed Control DialA speed control dial located on each operator station allows the operator to set a maximum travel speed which is important for producing a smooth, high-quality mat.
Center Control ConsoleThe center control console includes analog gauges, switches and a digital display for machine functions. The center console also houses a majority of the electrical components including the machine controller.
Machine ControllerThe machine controller integrates performance functions and allows the feeder and auger speeds to be set independently which extends component life.
Exclusive Material Delivery System
Productivity and quality enhancements are built-in features.
Mix DeliveryThe AP-1000D provides precise mix delivery with minimal operator monitoring through the most advanced material handling system.
Feeders Controlled IndependentlyLeft and right feeders in addition to the left and right augers are controlled independently. The ability to control these four components separately, through a machine controller, eliminates the need for feeder gates.
Mix Delivery Control
In order to control mix delivery, the operator sets a speed rate for each feeder that will maintain the desired mix level in the left and right auger chambers.
Once the feeder speeds are set, the ratio of feeder speed to the maximum auger speed is automatically maintained by the machine controller, even though the propel rate may change as the job progresses.
Ratio ControlThis ratio control capability is particularly helpful when paving wider on one side of the machine than on the other. Each feeder can be set at a specified speed to deliver the proper amount of mix that is needed.
Outboard Feeder DrivesIncreased live tunnel area provides easy servicing.
Variable speed feeders precisely control mix delivery while reducing wear and segregation.
Gateless Feeders Run Full of MixThe gateless feeders on the AP-1000D always run full of mix regardless of the speed required to fill the auger chamber. This is typically a slower speed than would be experienced with a paver utilizing feeder gates to control mix delivery rates. By not always having to run at full speed, feeder component wear is significantly reduced.
Changes in Feeder SpeedWhen changes in feeder speed are required, delivery of mix to the augers is immediate. This is in contrast to pavers with gates, where any delivery rate change is delayed for the length of time it takes to clear the tunnel of mix from the previous gate setting.
Running at Lower SpeedsRunning at slower speeds can also help reduce the opportunity for segregation, especially when working with larger stone mixes that have more of a tendency to segregate.
Feeder DesignTunnel construction improves mix flow.
Auger AssemblyProvides mat consistency while minimizing segregation.
