Cummins Engines for Urban Bus & ShuttleView Urban Bus & Shuttle Engines
Better. Where It Counts. Every Minute.
What counts is cleaner, more fuel efficient and more reliable engines to keep your buses on schedule. That’s what Cummins 2013 engines deliver, whether you are looking for diesel, natural gas or dieselelectric hybrid engines to power your urban bus fleet.
Not only do all of our Cummins transit bus engines meet U.S. Environmental Protection Agency (EPA) 2013 emissions standards, but they also meet 2014 greenhouse gas (GHG) and fuel efficiency standards a full year ahead of schedule. Our ISL9 and ISB6.7 clean diesel engines get up to 2 percent better fuel economy versus 2010 engines, while the Cummins Westport ISL G and ISB6.7 G take advantage of an abundance of domestically produced natural gas to provide lower total cost of ownership. These engines share common base engine components, for exceptional reliability and durability.
Cummins is the only engine manufacturer to design, develop and support a totally integrated system from the air handling to the exhaust aftertreatment. This allows us to optimize performance to a degree that no other manufacturer can match.
We’ve utilized our fully integrated technology to simultaneously improve fuel economy and performance, lowering operating costs as we reduce emissions to near-zero levels.
Cummins is a leader in hybrid diesel engines. Diesel-electric buses powered by Cummins ISB6.7 and ISL9 engines have completed millions of miles of reliable service throughout the world.
Our total commitment to delivering reliable power you can count on every minute, backed by the largest and most capable service and support network in North America, is the reason Cummins has been the #1 choice in U.S. urban transit fleets since 1998.
Leadership In Clean Diesel Technology.
Cummins is a leader in the development of diesel engines with near-zero emissions. Our fully integrated approach includes the Cummins Aftertreatment System with a Diesel Particulate Filter (DPF) that works in combination with our Selective Catalytic Reduction (SCR) system. The entire system is controlled by a single, robust Electronic Control Module (ECM), for optimized combustion, better performance and enhanced reliability.
Cummins 2013 ISL9 diesel is equipped with a proven On-Board Diagnostics system used in thousands of on-road vehicles since 2007. This system continuously monitors performance of the emissions system, providing alerts through a Malfunction Indicator Lamp (MIL) on the instrument panel. The MIL illuminates when it detects a malfunction related to the emissions control system, altering the operator that the engine needs proper troubleshooting and possible repair.
Alternative Technologies – Natural Gas And Hybrid Engines.Find a Cummins Sales or Service Location
At Cummins, we recognize that just talking about climate change and environmental impact aren’t enough. So, in addition to offering clean-diesel engines, we're at the forefront of alternative technologies that can help reduce our dependence on fossil fuels, and lower GHG emissions. These include the ISL G and ISB6.7 G natural gas engines from Cummins Westport and our ISL9 and ISB6.7 diesel-electric hybrid engines.
The Cummins Westport ISL G is the most popular natural gas engine in North America today, delivering all the advantages of clean-burning natural gas with no compromise in power or torque. The ISB6.7 G, available in 2016, features the same advanced combustion technology and offers a midrange natural gas solution for urban bus and shuttle applications.
Cummins ISL9 and ISB6.7 engines are used in a wide range of hybrid diesel-electric systems found in 30- to 60-foot standard and articulated buses all across North America.
