Cat® C7 Engine with ACERT® Technology
ACERT® Technology incorporates a series of innovations working at the point of combustion to optimize engine performance while meeting U. S. EPA Tier 3 and E. U. Stage IIIa engine emission regulations.
Cat® C7 Engine with ACERT® Technology
The 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 (643 ft/lb). The combination of large displacement and high torque allow the AP-1055D to perform under the toughest conditions.HEUI Fuel Injection
The 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 Delivery
Multiple 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 Pressures
High cylinder pressures combined with tightly controlled tolerances promote extremely efficient fuel burn, less blow-by and lower emissions.C7 Cylinder Block
The 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.Sound Reduction Features

Air-to-air aftercooling keeps air intake temperatures down, maximizing fuel efficiency and minimizing emissions.ADEM™ A4 Electronic Control Module
The 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.
High Ambient Temperature Cooling System
The standard, high-capacity cooling system provides efficient operation in high ambient temperatures. The new system design also provides quiet operation that benefits the operator and the surrounding environment.
The airflow design draws ambient air across the engine compartment and through the radiator. This new design allows the exhaust air to exit the right side of the machine in order to provide a cooler engine compartment and operator platform.High Capacity Cooling Package

Exclusive Material Delivery System
Productivity and quality enhancements are built-in features.
The AP-1055D provides precise mix delivery with minimal operator monitoring through the most advanced material handling system.Feeders Controlled Independently
Left 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 champbers. Once the feeder speeds are set, the ratio of feeder speed to the maximum auger speed is automatically maintained by the machine controller, even through the propel rate may change as the job progresses.Ratio Control
This 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 Drives
Increased live tunnel area provides easy servicing.
Variable speed feeders precisely control mix delivery while reducing wear and segregation.
Gateless Feeders Run Full of Mix
The gateless feeders on the AP-1055D 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 Speed
When 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 Slower Speeds
Running 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.
Tunnel construction improves mix flow.
Provides mat consistency while minimizing segregation.
