D976
Power generation
Highlights
Designed and manufactured by Liebherr, the D976 is a benchmark combustion engine engineered for mission critical power generation applications, particularly wellsuited for PRP and COP operations while also supporting standby power requirements in stationary and mobile installations, including rental fleets and data centers. Built on a robust platform and backed by Liebherr’s proven engineering expertise, this 6 cylinder, 18 litre engine delivers up to 820 kW, offering outstanding flexibility across PRP and COP duty cycles, covering both constant and variable load profiles over extended running hours. Combining high engine efficiency with optimised fuel consumption and controlled emissions performance, the D976 is designed to deliver reliable and cost effective power generation across demanding PRP and COP operating profiles. Extended service intervals, simplified maintenance and the advanced LiDIA diagnostic tool maximise reliability, minimise downtime and secure long term asset value.
