Liebherr has showcased its megawatt-class G9620 engine to the Chinese genset and combined heat and power market.
The Swiss firm’s new gas engines, which are designed for decentralised energy supply plants— especially non-stop operation in combined heat and power units, biogas plants or gensets— were presented at the International Power and Generating Sets Exhibition (G-Power) in Shanghai.
The 20-cylinder gas engine G9620 features a displacement of 48.7 litres, over 44% mechanical efficiency and the power output of 1,070 kWm at 50 Hz and 60 Hz.
Liebherr said the G9620, suitable for both applications with natural or biogases, has 'high efficiency' and 'high response' versions, which allow the unit to fulfil either continuous operation with a high demand on efficiency or island operations with higher load steps and variations.
“To simplify the work of packagers and allow better flexibility in applications, the G9620 engine includes integrated air filters, on-engine Liebherr ECUs with calibrated datasets and a new water-cooling concept,” the company said.
According to Liebherr, the number of connections such as water circuits, electrical, or electronic connections,is kept to a minimumtoreduce the integration time of the G9620 into cogeneration units.
