ECU2-HD Engine control unit

The robust Liebherr engine control unit ECU2-HD is ideal for use in extreme conditions. The engine control is suitable for the operation of diesel engines and stationary gas engines with up to 12 cylinders. As a cascaded solution, up to 20 cylinders can be controlled. ECU2-HD also contains the necessary scope for the direct control of a SCR or SCRFilter system. This makes it possible to fulfil the various emissions standards such as EU Stage IV/V, EPA CARB Tier 4f, as well as Euro V/VI. The control was developed in line with international safety standards and enables functional safety requirements of function chains to be fulfilled.

Supported emission standards Euro V / Euro VI / EPA Tier 4f / EU Stage IV / EU Stage V
Supported engines Diesel engines / Stationary gas engines (CNG)
Number of supported cylinders 12
Supported injection systems Common-Rail-Systeme
Integrated SCR control interface yes
