Highlights

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 Systems. The ECU2 HD controls all engine functions as well as the Liebherr SCRonly or SCRFilter systems, including Ad-Blue (DEF) dosing The engine control unit enables the fulfillment of various emission regulations, e.g. EU Stage IV / V, Euro V and EPA Tier 4f. The control 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.
