Product description
Technical description
The low pressure system is supplied by the fuel pre-feed pump which ensures the circulation
from the tank and pre-feeds the high pressure system.
The high pressure system leads the pressurized fuel from high pressure pump to the injectors.
The high pressure system is secured by a pressure control valve.
Electronic Control System
Information
To connect the interfaces, refer to the "Electrical Installation Guideline" of your engine applica‐
tion and generation.
The information on the engine control unit nameplate corresponds to the delivery status.
Depending on software updates in the field, it may be the case that this information is no
longer up to date.
The real information can be viewed in the device display or read out with the diagnosis and
service tool KoDIA.
The engine control system consists of a programmable engine control unit.
The ECU controls the actuators and reads values from the sensors to ensure optimal engine
performance.
The ECU is programmed according to configuration and application. Mappable parameters
among others are:
– Maximum RPM
– Cooling temperature correction
– Transient fueling
The diagnosis and service tool KoDIA provides several functions including:
– General information
– Status overview
– Configuration adjustement
– Error list information
– Process data list
– Oscilloscope
– Direct triggering
– Main values display
– CRS visualization and operation
– Long-term error memory
– Fault reactions
Engine electronic sensors
The engine sensors are interfaces for external monitoring of the following parameters:
– Charge air pressure
– Fuel pressure
– Rail pressure
– Oil pressure
– Coolant temperature
– Charge air temperature
– Engine speed and position
The engine actuators are interfaces for the following control functions:
– Starters
– Volume control valve
– Pressure control valve
