CHAIRMAN’S AWARD

Project targets emission reductions

Congratulations to James Cui, Technical Support Manager – HHP, who has won a Chairman’s 2020/2021 Impact Award for environmental impact.

His project reduces particulate matter, CO2 emissions and fuel consumption for mining haul trucks. Chairman and CEO Tom Linebarger said Chairman’s Impact Award recipients embody the Cummins’ values of excellence and teamwork, and their work positively impacts on numerous stakeholders, including employees, communities and customers. “The outcomes for their projects will have a lasting effect, and I commend their commitment to delivering results,” he said.

To be considered for a Chairman’s Impact Award, projects must have been completed three years ago and have demonstrated sustained or expanded impact since then. James’s project was launched to reduce particulate matter (PM) by 25% fleet wide to meet new New South Wales (NSW) Government Environmental Protection Authority (EPA) requirements for in-service mining equipment. The requirements were introduced because PM has a negative impact on the environment and human health and significantly increases public health costs in NSW. The Cummins team proposed an in-cylinder combustion optimisation solution to reduce PM emissions during consultation on the new regulations, which EPA accepted. Cummins’ solution was to rebuild QSK60 MCRS Advantage engines on Komatsu 830E mining trucks to meet PM reduction targets, offer fuel economy improvements, reduce CO2 emissions and extend engine life. The PM reduction achieved was 60.6%, CO2 emissions reduced 4.8%, fuel econopmy improved 4.8%, and engine life was extended by 15.5%. The industry and NSW EPA now consider the QSK60 MCRS Advantage engine the benchmark and it is the preferred engine for mining trucks. Project benefits include: • Total savings since project closure USD7.8 million in reduced fuel use and carbon emissions • Total engines in operation since 2017 = 114 • MCRS Advantage engines are an option from the Komatsu factory and standard as part of aftermath rebuilds in Asia

Pacific • CMI issued a brochure in 2019 to promote QSK60 MCRS

Advantage engines • Technical details were shared with Cummins Latin America in 2020 to support their promotion to Anglo American in Brazil • Project replicated with other customers, including Rio Tinto,

Peabody, HSE Mining • MCRS Advantage engine has been extended to the Komatsu 930E truck.

The project sponsors were Paul Corbett and John Bortolussi, project MBB was Ainslie Fisher, and team members were Justin Blomenberg, Joe Reynolds, Karthik Gopal, Manoj Bhagwal, and Tim Smith.
