Cummins Inc. (NYSE: CMI) today announced three innovations at MINExpo to deliver cleaner, powerful and reliable engines and related technology to mining customers.
The first innovation is Cummins’ plans to produce dual-fuel engines for mine-haul trucks. The Cummins Dual Fuel
engine technology substitutes natural gas for diesel fuel in the combustion process, reducing the amount of diesel fuel required to operate mining equipment. The first engine in the Cummins Dual Fuel portfolio for mining is the QSK60, with other QSK Series engines to follow, including engines capable of meeting U.S. Environmental Protection Agency (EPA) Tier 4 Final emissions standards.
The QSK60 is available in standard and high-altitude configurations, and both will be capable of substantially reducing fuel costs with Cummins Dual Fuel technology. Cummins Dual Fuel engines will use integrated controls that will optimize the substitution rate based on operating conditions, and will seamlessly and automatically transition between diesel fuel and dual-fuel modes. Cummins Dual Fuel technology enables mining equipment to operate in 100 percent diesel fuel or in dual-fuel mode, giving the customer flexibility depending on natural gas availability at the mine site.
The second innovation announced was to increase high-horsepower engine remanufacturing capacity by 100 percent, to approximately 7,000 units per year by 2016, in order to meet demand for a rapidly expanding population of mining equipment powered by the popular QSK and K Series engines. Cummins’ engine rebuild process ensures that the equipment operator receives a rebuilt engine with “as-new” standards of reliability and performance.
A global network of highly specialized rebuild facilities are located in areas aligned with high populations of Cummins-powered haul trucks, loaders, excavators, drill rigs and other mining equipment. The investment program will establish a number of additional engine rebuild facilities in new locations, as well as expand many of the existing facilities.
