ECU 3 Engine control unit

The Liebherr engine control unit ECU 3 impresses in on- and off-road applications as a cost-effective control with optimised functions for 6-cylinder diesel engines and mobile gas engines. In addition, the ECU 3 includes an interface for the direct control of a SCR or SCRFilter system, and impresses with an optimised cooling concept. This makes it possible to fulfil the various emissions standards such as EU Stage IV / V, EPA Tier 4f, as well as Euro V /VI. The control unit is certified according to the road approval ECE-R10. The engine control was also 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 / Mobile gas engines (NG)
Number of supported cylinders 6
Supported injection systems Common-Rail-Systeme
Integrated SCR control interface yes
