CUMMINS ENGINE BUSINESS PRODUCES ENGINES FOR ON AND OFF-HIGHWAY USE.
The engines range from engines for pickup trucks, school buses and large tractor-trailers hauling freight to engines for construction, agriculture and industrial uses.
Pollutants in engine emissions have declined significantly in North America since the U.S. Environmental Protection Agency (EPA) began regulating them in the 1970s. On-highway diesel engine emissions, for example, are down more than 95 percent for particulate matter (PM) and oxides of nitrogen (NOx), reaching near-zero emission levels.
Advances in fuel economy, meanwhile, have greatly reduced the output of carbon dioxide (CO2) and by extension, greenhouse gases (GHGs). CO2 is a key contributor to climate change.
Cummins has been a pioneer in clean diesel technology, advances in combustion, electronic controls, fuel systems, filtration, air handling, exhaust aftertreatment and more to reduce emissions and improve fuel economy. The company has achieved these advances working on its own and in partnership with others.
In addition to diesel, the company has also been a leader in the development of engines that run on biodiesel, natural gas and other alternative fuels to provide customers with the option that best works for them to meet their own sustainability goals.
Here are some of the most significant environmental sustainability developments in the Engine Business in 2015 and early 2016:
Cummins announced in November 2015 that its QSK19 engines will power two of the new models in John Deere’s 8000 Series Self-Propelled Forage Harvesters lineup – the 8700 at 755 hp (563 kW) and the 8800 at 832 hp (620 kW). The machines offer forage producers more productivity, increased uptime and are designed with the latest forage-harvesting technology.
NOTABLE: These models also provide forage producers with a more efficient cost of operation with improved fuel efficiency – up to 6 percent (gallons per ton) in corn and up to 15 percent (gallons per ton) in grass. When packaged alongside the stronger design and higher-horsepower performance of the QSK19, these machines will provide years of reliable service.
Power management company Eaton announced with Cummins in November 2015 an expanded lineup of the integrated ISX15 SmartAdvantage powertrains to provide customers with additional choices tailored to their unique needs.
NOTABLE: The new SmartAdvantage direct drive ratio is available in Cummins ISX15 400 hp and 450 hp ratings with 1550/1750 ft.-lbs. torque-rating, ensuring optimal performance at lower rpm when combined with a 2.26 or 2.28 axle ratio. This package is the ideal solution for line haul or regional haul applications that operate in flat and hilly road terrains at cruise speeds in the 50 to 62 mph range.
CONNECTED DIAGNOSTICS MOBILE APP
Cummins in February 2016 released its Connected Diagnostics mobile app, which provides guidance and actionable information delivered directly to a customer’s mobile phone.
NOTABLE: The app complements Cummins’ popular fault monitoring application by providing features such as a status page listing the customer’s connected equipment and is organized by the engine system’s fault code status.
Connected Diagnostics is a customer’s lifeline to Cummins. Through a telematics connection, a customer’s Cummins-powered equipment wirelessly connects the engine to Cummins for immediate diagnosis of an engine system fault, providing the customer valuable information within seconds.
Cummins in February 2016 released three new ISX15 ratings ideal for premium fleets or performance-oriented line-haul applications. The new 475-, 450- and 400-horsepower ratings with 1850 lb-ft of torque provide an optimal blend of performance and fuel efficiency for high-load applications or fleets that encounter mountainous terrain. NOTABLE: Customers who traditionally opted for a 485 hp or 500 hp rating can now benefit from the superior fuel economy of operating at a lower rpm while satisfying performance expectations.
F3.8, B4.5, B6.7 and L9
Cummins revealed in April 2016 a new generation of ultra-low emissions engines, spanning from 100 hp to 430 hp, that are designed to meet stringent 2019 European Union Stage V emissions regulations for construction, mining and material-handling equipment. NOTABLE: The engines use the Single Module aftertreatment, but do not include Exhaust Gas Recirculation (EGR), allowing for a simpler architecture that results in more power and torque. The engines were unveiled at bauma, the world's largest trade fair in the construction industry held every three years in Munich, Germany.
