Figure 24. Common Powertrain Controller
DDEC 10 System - EPA10/GHG14
All engines for 2010 are equipped with an electronic control system called Detroit
Diesel Electronic Control (DDEC10). The electronic engine control system
regulates the fuel injection quantity and timing using solenoid valves, allowing
extremely low-emission operation. Besides the engine and its related sensors, the
system has three other control modules:
Motor Control Module (MCM)
Common Powertrain Controller (CPC)
Aftertreatment Control Module (ACM)
The three control units are connected by a proprietary datalink through which all
necessary data and information can be exchanged. EPA10 and GHG14 units
operate on the same hardware.
The MCM monitors both the engine and the datalink. When a malfunction or other
problem is detected, the system selects an appropriate response; for example, the
emergency running mode may be activated.
The MCM processes the data received from the CPC, for example, the position
of the accelerator pedal and engine brake.
This data is evaluated together with the data from the sensors on the engine, such
as coolant and fuel temperature and oil and charge pressure. The data is then
compared to the characteristic maps or lines stored in the MCM. From this data,
quantity and timing of injection are calculated.
