At MINExpo International 2012, now being held in Las Vegas, Tom Linebarger chairman and CEO of Cummins Inc. reported that they continue working under the theme “ready for more” including the following basic ways:
1. Expanding product line at high and low end. Currently the company produces engines ranging from 49 to 4,200 horsepower.
2. Using company’s SCR component to meet Tier 4 standard.
3. Expansion and improvement of customer service, including an emphasis on remanufacturing. Cummins expects rebuilding process to mirror by 90 percent its new build process. By 2016 rebuild capacity should be doubled.
In addition, Cummins starts production of dual fuel natural gas options. The first dual-fuel engine is Cummins QSK60, which is now being tested, and should appear in the coming months.
According to Cummins dual-fuel engines will have integrated control system, which will optimize the substitution rate based on operating conditions, transitioning between dual-fuel and diesel modes.
The use of dual-fuel engines is a huge opportunity in mining, since mining trucks use about 1.5 million gallons of fuel a year. Installation of dual fuel engines can help to save about $500,000 per truck per year.
