ECU2 Engine control unit

The Liebherr engine control unit ECU2 for diesel engines with up to eight cylinders is also suitable for stationary gas engines. It is perfectly matched to the Liebherr Common Rail Systems. An interface for direct control of the SCR or of the SCRFilter system allows a combined regulation of engine and exhaust gas treatment with only one ECU2. The engine control unit enables the fulfillment of various emission regulations, e.g. EU Stage IV / V, Euro V / VI and EPA Tier 4f. The ECU2 is certified according to road registration ECE-R10. The control unit fulfills the functional safety requirements of function chains according to international safety standards. Due to the integrated self-diagnosis, the ECU2 checks itself, which facilitates maintenance. Integrated fuel cooling ensures safe and reliable operation of the ECU2, even in case of strong heat generation.
Supported emission standards EU Stage IV / EU Stage V / EPA Tier 4f / Euro V / Euro VI
Supported engines Diesel engines / Stationary gas engines (CNG)
Number of supported cylinders 8
Supported injection systems Common-Rail-Systeme
Integrated SCR control interface yes
