The opening day of INTERMAT highlighted a strong presence of Cummins engines in equipment meeting low emissions requirements in the 75 to 751 hp low-emissions power category. Cummins power was featured in a wide variety of machines, from site dumpers to excavators, cranes to compressors, forklifts to compactors, and wheel loaders to road milling machines.
Significant productivity improvements and fuel-efficiency gains have been realized for the machines with the transition to low-emissions engines, highlighting how Cummins brings Technology That Transforms to each application - not just with ultra-clean power, but also with improved response and lower operating costs.
The move to near-zero emissions at U.S. Environmental Protection Agency (EPA) Tier 4 Final (European Union Stage IV) has been achieved with an additional reduction in fuel consumption to that achieved at Tier 4 Interim (Stage IIIB). Depending on application, Cummins-powered machines are able to realize up to 8 percent improved fuel-efficiency compared with their pre-2011 Tier 3 (Stage IIIA) equivalents. With the full potential of Tier 4 technology utilized, even higher savings have been achieved with features such as torque shaping, idle control and eco-operating modes.
Importantly, the advantage of low-emissions engines comes with no compromise to reliability. That has been confirmed by Cummins in-service reports based on a large engine population in operation since the use of exhaust aftertreatment.
Analyses of warranty data and service events clearly indicate that Cummins low-emissions engines are delivering uptime availability levels at least equal to that of previous Tier 3 (Stage IIIA) engines with a long-established reputation for reliability.
"In-service dependability is a key attribute of Cummins low-emissions technology, and our tracking of the Tier 4 engine population is clearly indicating that equipment operators are seeing uptime availability and minimal service intervention equally impressive as what they experience with our mature Tier 3 engines," said Hugh Foden, Executive Director - Cummins Off-Highway Business.
The ability to transform machine performance is reflected in the theme of the Cummins booth (L028, Hall 5b), featuring a 49 hp-to-675 hp (37-503 kW) engine range compliant with Tier 4 Final and Stage IV regulations. The engines have been specified for over 400 machine integration projects by almost 70 equipment manufacturers.
The engine lineup includes the 4-cylinder QSF2.8 and QSF3.8, targeted toward compact equipment, along with the new QSG12, providing heavy-duty power for high-output machines. The engine lineup also includes the midrange QSB4.5, QSB6.7 and QSL9, together with the top-of-the-range QSX15. Cummins portfolio of key enabling technologies will be showcased, with complete air intake-to-aftertreatment exhaust-out systems and components.
Tried And Tested
The reliability of Cummins near-zero emissions technology was established with a Tier 4 Final and Stage IV field-test program clocking over 150,000 hours and involving almost 70 machines, spanning across North America and Europe.
In a variety of tough environments - from the cold, high altitude of the Alps to the extreme dry heat of Texas - the field-test work specifically targeted the toughest installation and operational challenges in order to gain the broadest experience and to have total confidence in the ability of the engines to deliver.
A specialized field-test team of dedicated Cummins service engineers and a wider team of around 100 design and application engineers led the work on the field-test program. As well as monitoring activity in person, engineers employed remote monitoring technology in order to fine-tune engines and ensure optimum performance for various duty cycles.
