Short Description Engine Control Unit – ECU2-HD Uncompromisingly robust: The ECU2-HD, rated IP6K9K, can be used under harsh conditions with connected or disconnected cable harness. The control is suitable for diesel engines and stationary gas engines with up to 12 cylinders. As a cascaded solution, it controls up to 20 cylinders. The ECU2-HD matches perfectly to the Liebherr Common Rail System. 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-HD. The control unit enables the fulfillment of various emission regulations, e.g. EU Stage IV  V, Euro V  VI and EPA Tier 4f. The con/  /  trol unit fulfills the functional safety requirements of function chains according to international safety standards. Due to the integrated self-diagnosis, the ECU2-HD checks itself, which facilitates maintenance. Integrated fuel cooling ensures safe and reliable operation of the ECU2-HD, even in case of strong heat generation. Features • Platform for EU Stage IV / V, Euro V / VI and EPA Tier 4f • Combined control of engine and exhaust gas treatment • 12 power outputs for injector activation • Control of up to 20 cylinders in cascaded use • Integrated knock control for stationary gas engines • Suitable for direct mount on the engine • High functionality of self-diagnostic for a safe operation • Standardized communication interfaces: J1939, UDS • Functional safety according to EN ISO 13849 • Temperature range from -40° C to +125 °C
