Liberty Energy Inc. 和康明斯公司正在部署于 2024 年合作开发的天然气大排量发动机。
康明斯公司（Cummins Inc.）与Liberty Energy Inc.宣布，业界首款天然气变速大排量发动机将于2025年上半年投入使用，为Liberty的digiPrime水力压裂平台提供动力。
两家公司于 2024 年 6 月建立战略合作伙伴关系，共同为完井服务市场开发革命性技术。
Liberty digiPrime 平台的新开发充分利用了现有的 HSK78G 平台。它提高了 78 升天然气火花点火发动机的响应时间和运行期间的负载接受能力。
digiPrime 泵由 3,000 马力的康明斯天然气变速发动机驱动，是一种有助于降低燃料成本的直接驱动解决方案。两家公司表示，新发动机比标准柴油发动机更易于维护和操作。
Liberty 总裁兼首席执行官继任者Ron Gusek表示：“变速 digiPrime 泵的成功开发反映了我们对泵技术创新的持续承诺，这种创新可在降低排放的同时提高效率目标。”

Liberty Energy Inc. and Cummins Inc. are deploying the natural gas large displacement engine developed in a partnership formed in 2024.
Cummins Inc. and Liberty Energy Inc. announced that the industry’s first natural gas variable-speed, large displacement engine will be deployed in the first half of 2025 to power Liberty’s digiPrime hydraulic fracturing platform.
The companies entered into a strategic partnership in June 2024 to jointly develop the revolutionary technology for the completions services market.
The new development for Liberty’s digiPrime platform leverages the existing HSK78G platform. It improves the 78-liter natural gas spark-ignited engine’s response time and load acceptance during operation.
The digiPrime pump, anchored by a 3,000 hp Cummins natural gas variable-speed engine, is a direct drive solution that helps reduce fuel costs. The companies said the new engine is easier to maintain and operate than a standard diesel engine.
“The successful development of the variable-speed digiPrime pump reflects our continued commitment to innovation in pump technology that advances efficiency goals while reducing emissions,” said Ron Gusek, president and named successor to the CEO of Liberty.
