Двигатель фронтального погрузчика NEW HOLLAND - 
EDC 7 Common Rail


A – Injectors connector B – Connector for power input and functions provided for in the application C – Sensors connector
The control unit is installed on flexible mounts to reduce vibration transmitted by the engine. It is installed over a fuel heat exchanger which limits the engine heat transmitted to the controller.
The unit is supplied with power by a 20 A fuse. The main relay normally used to supply the system is located inside the control unit.
