How Complex Is The Electric Unit Pump System Of Deutz Engine?

Deutz Electric Control Unit Pump System Bosch

Magnetoelectric Sensor Of Pump System

Camshaft speed sensor :

● determine TDC;

● it can be used as a backup function of crankshaft sensor.

Crankshaft speed sensor:

● determine engine speed and engine position;

● it can be used as a backup for camshaft sensor.

Camshaft sensor – provides top dead center position during starting; With the crankshaft sensor, it takes 15s to find the upper point position;

Pressure Sensor

Charge air pressure sensor of pump system
Avoid soot generation and limit injection at low boost pressure.
Oil pressure sensor (optional)
Monitor the oil pressure, protect the engine and stop at low oil pressure.
Atmospheric pressure sensor
Protect supercharger – when driving on high altitude, the engine can be protected by reducing engine power.
temperature sensor
Boost temperature sensor
Sensing air volume, determining air density, optimizing injection volume and injection timing.
Fuel temperature sensor
Used for correction of injection quantity.
Coolant temperature sensor
Protect the engine when the engine temperature is too high, and optimize the injection quantity and injection timing when the cold start and ambient temperature are too low.

Position Sensor

Pedal travel position sensor

Transfer the driver’s expectation of vehicle acceleration to the control unit (ECU)

Introduction To Control Unit:

The control unit has two interfaces, one connected to the engine and the other connected to the whole vehicle, and the ambient pressure sensor is installed in it of pump system.

Engine control function

● engine start

● idle speed controller to increase idle speed in cold weather

● torque controller

● speed controller

● intermediate speed controller, mainly used for construction machinery

● high idle controller
