In the harsh scenarios of mining operations, continuous high-intensity and high-load operation is the norm. The performance of each mining construction machinery directly determines the overall efficiency of mining, equipment attendance rate and comprehensive operating costs. As the "heart" of mining excavators, the quality and adaptability of diesel engines are the core lifeline of efficient mining production — Cummins, with nearly a century of experience in the mining power field, injects strong momentum into various mining construction machinery with professionally customized diesel engine technology, becoming a reassuring choice for mining operators.

Recently, LiuGong's 20-ton flagship mining excavator 920FMAX+ was newly launched. This construction machinery tailored for heavy-duty mining conditions takes the specially customized B7 mining diesel engine by Cummins as its core power source. Relying on Cummins' profound power R&D heritage and practical experience in mining scenarios, this customized diesel engine perfectly adapts to the operating characteristics of excavators, integrating three core advantages of strong power, reliability and durability, and high efficiency and fuel saving. It has become the core support for empowering efficient mining operations and a benchmark choice for the power configuration of mining excavators.

As a star product of the Cummins power family specially built for mining construction machinery, the Cummins B7 mining diesel engine is inherently suitable for the harsh environment and heavy-load needs of mining, and can be called a "powerhouse" and "energy-saving expert" for mining operations. With a stable output of 135kW high power, its torque performance is far superior to that of competitors at the same level, greatly improving the digging force and operating speed of the excavator. Whether it is the crushing and loading of hard ore or continuous high-intensity earthwork operations, it can easily handle them with sufficient safety margin. It completely solves the pain points of insufficient power and intermediate speed drop in mining operations, allowing each mining excavator to operate at full load efficiently.

Aiming at the pain points of complex mining operation environment and high equipment failure rate, the Cummins B7 mining diesel engine adopts the advanced SCR emission technology route, combined with Cummins' unique non-inductive regeneration technology. It can realize the synchronous progress of exhaust gas purification and engine self-inspection without manual intervention. It not only greatly reduces the failure rate of diesel engines and reduces the equipment downtime for maintenance, but also meets the increasingly strict global emission standards for non-road mobile equipment, enabling mining construction machinery to achieve green and environmental protection compliance while operating efficiently and helping the green and sustainable development of mining.

In terms of operational comfort and economy, the Cummins B7 mining diesel engine also performs excellently. The internal structure of the engine has been precisely optimized, with smooth and consistent work, low vibration and low noise during operation. Combined with the comfortable cab design of the LiuGong 920FMAX+ excavator, it significantly reduces the work fatigue of operators and makes long-term mining operations easier. At the same time, the engine is equipped with an intelligent control module, which can flexibly switch between E/P working modes. The P mode outputs at full capacity, adapting to high-intensity heavy-load working conditions to ensure operational efficiency; the E mode saves fuel intelligently, adapting to light-load working scenarios to effectively reduce fuel consumption. Combined with its minimum specific fuel consumption advantage of 181g/KW-h, it can save 5%-10% of fuel under typical working conditions, greatly reducing the operating costs for mining enterprises and achieving dual improvement of efficiency and economy.

The excellent quality of Cummins power is never empty talk, but comes from the actual verification of numerous mining scenarios and the high recognition of the majority of mining construction machinery users. In a large stone mining area in Beibu Gulf, Guangxi, the ore loading operation here has extremely high load and intensity, which is an extremely severe test for the power performance and durability of mining excavators. Liang Yinghai, as the person in charge of mining equipment managing dozens of mining construction machinery, has been deeply engaged in the mining field for many years. What he values most is whether the equipment power is "reliable" and whether it is reliable and worry-free. The Cummins B7 mining diesel engine equipped on the LiuGong 920FMAX+ has completely dispelled his worries.

"The Cummins B7 engine equipped on this 920FMAX+ has really strong power. Whether it is loading hard ore or operating continuously for a long time, there will be no power attenuation. It is very confident to drive. The loading efficiency is significantly higher than that of other models used before, which greatly reduces the waiting time of vehicles in the queue," Liang Yinghai sighed sincerely. In his opinion, for mining operations, the reliability, fuel saving and comfort brought by Cummins diesel engines are real productivity, and also the key to reducing operating costs and improving mining efficiency.

From the efficient operation of each mining excavator to the capacity improvement of each mining area, Cummins has always empowered various mining construction machinery with professional mining diesel engine technology, driven the efficient development of mining with strong power, guarded the safety of each operation with reliable quality, and helped mining reduce costs and increase efficiency with energy-saving advantages. In the future, Cummins will continue to deepen its presence in the mining power field, rely on continuous technological innovation to create more adaptive to mining scenarios and more competitive diesel engine products, inject stronger, more reliable and greener Cummins power into global mining operations, and work hand in hand with major mining enterprises and construction machinery manufacturers to build a new future of efficient, green and sustainable mining development.
