PRELIMINARY
The MBE 900 engine utilizes electronically controlled fuel injection and cooled exhaust gas
recirculation as the primary emission control technologies. The engine's DDEC-ECU utilizes
algorithms and several sensor inputs for management of the fuel injection and EGR systems.
See Figure 2-12 and Figure 2-13 for sensor locations.
