The 1506 industrial engine has three different emissions ratings A, C, and D. The 1506 industrial engine can be configured for variable speed applications or constant speed applications. The 1506A and C industrial engines have five different ratings. Visually the engines will look similar the difference is due to the software that is loaded into the engine Electronic Control Module (ECM). The 1506D may be configured differently, with an air inlet heater, automatic tensioner for the drive belt, and a turbocharger with a wastegate actuator.

The Perkins 1506A, 1506C and 1506D industrial engines have the following characteristics:
- In-Line 6-cylinder
- Four-stroke cycle
- Hydraulically Actuated Electronic Unit Injection (HEUI)
- Turbocharged with air-to-air aftercooled (ATAAC)
Electronic Engine Features
The engine operating conditions are monitored. The ECM controls the response of the engine to these conditions and to the demands of the operator. These conditions and operator demands determine the precise control of fuel injection by the ECM. The electronic engine control system provides the following features:
- Engine speed governor
- Automatic air/fuel ratio control
- Torque rise shaping
- Injection timing control
- System diagnostics
For more information on electronic engine features, refer to the Operation and Maintenance Manual, “Engine Diagnostics” topic.
The following additional features provide increased engine fuel economy and serviceability:
- Cold starting capability
- Tampering detection
Hydraulic Electronic Unit Injectors Hydraulically Actuated Electronic Unit Injectors (HEUI) perform the following function:
Atomizes the fuel: The unit injectors are controlled by the ECM which uses the camshaft position, the engine speed signals, and the inlet air pressure sensors. The ECM controls when the fuel is injected into each cylinder. The rated rpm is identified on the information plate.
The engine has built-in diagnostics in order to ensure that all of the components are functioning properly. In the event of a deviation from the programmed limits, the operator will be alerted to the condition by a “DIAGNOSTIC” lamp. Under certain conditions, the engine horsepower and the vehicle speed may be limited. The electronic service tool may be used to display the diagnostic code.
Engine Service Life
Engine efficiency and maximum utilization of engine performance depend on the adherence to proper operation and maintenance recommendations. In addition, use recommended fuels, coolants, and lubricants. Use the Operation and Maintenance Manual as a guide for required engine maintenance.
