Another step in the development of gas engines by Liebherr

February 6 2017

With the new 20-cylinder gas engine G9620, Liebherr takes another step in the development of gas engines and expands its portfolio for gas applications.

Following the strategy initiated in 2013 for the delivery of fully equipped gas engines, the Liebherr Components division now enters the megawatt market with its new gas engine development. The 20-cylinders gas engine G9620 features a displacement of 48.7 litres, 44% mechanical efficiency and the power output of over 1,000 kWm. It was presented to the public at the EnergyDecentral in Hannover (Germany) from 15th to 18th of November 2016.

The G9620 include integrated air filters, on-engine Liebherr ECUs with calibrated datasets and a new water-cooling concept. This is simplify the work of packagers and allow greater flexibility in applications. As its predecessors, the engine design follows the concept of a 'plug and play' solution. The number of connections, that is the water circuits and the electrical or electronic connections, are limited to a minimum. Combined with integrated filters, this greatly reduces the amount of time and efforts OEMs have to spend integrating it into cogeneration units. Moreover, it is also guarantee OEMs the matching subcomponents. On developing the product, Liebherr puts special focus on an optimised lifecycle and operation costs to create the highest costumer advantage.

"The new gas engine by Liebherr available in two basic versions - a 'high efficiency' and 'high response' version", explains Martial Suchet, Head of Sales Gas Engines at Liebherr. "With them, Liebherr will cover the most applications on a wide spectrum of different gases, for example, gases with different energy values as well as gases with different methane numbers. Applications both in net parallel work and island mode, as well as in 50 or 60 Hz applications are further planned for development", continues Martial Suchet. "This flexibility is possible thanks to only a few adjustments and some geometric aspects, but mainly thanks to our on-board electronics. The electronic control units are steering all essential engine functions, such as knocking control, ignition control, power control, lambda control, safety controls".
