DDEC Common Rail Electronics (CRE) is the electronic control system for common rail fuel injection systems in Detroit Diesel engines. It is responsible for controlling the fuel injection timing and quantity, as well as other aspects of engine operation, such as idle speed and turbocharger boost.
The Series 4000 common rail fuel injection system relies on a single high pressure fuel pump that
provides a continuous supply of fuel, at injection pressure, to all of the injectors.
provides a continuous supply of fuel, at injection pressure, to all of the injectors.
The ECM(s) receives data (such as engine temperatures and engine speed), analyzes this data,
and modulates the fuel system accordingly to ensure efficient engine operation. The signals
that the ECM(s) sends to the high pressure pump determines the timing and amount of fuel
delivered to each cylinder.
