D9620

Power generation

Highlights

Designed and manufactured by Liebherr, the D9620 is a very highpower combustion engine developed for PRP and COP power generation applications, while also supporting standby power requirements in stationary installations where operational stability and longterm asset protection are key decision factors. Built on a robust platform and backed by Liebherr’s proven engineering expertise, this 20cylinder, 45litre engine delivers up to 1,910 kW, providing stable and predictable performance across PRP and COP duty cycles under demanding operating conditions. Combining reliable efficiency with optimised fuel consumption and controlled emissions performance, the D9620 is designed to deliver robust and costeffective power generation at very high-power levels. Extended service intervals, simplified maintenance concepts and advanced diagnostics with LiDIA support high availability, minimise downtime and help protect longterm asset value.
