Whether you are looking for a diesel, alternative fuel or a diesel/electric hybrid to power your city buses, Cummins has you covered. Our entire range of engines is built from proven core technology that's been continuously refined and improved so that those engines deliver better performance, every day and every route. This includes our proprietary VGT™ Turbocharger and an Exhaust Gas Recirculation (EGR) cooler that's been upgraded for enhanced reliability.
All Cummins transit bus engines meet EPA 2010 emissions standards. We've utilized our fully integrated technology to simultaneously improve fuel economy and performance, lowering operating costs as we lower emissions to near-zero levels.
Cummins is the only engine manufacturer to design, develop, manufacture and support nearly every component from the air intake to the exhaust aftertreatment in a totally integrated system. This allows us to optimize critical systems and deliver the right technology in a way that other manufacturers using outside suppliers simply can't match. Current bus engine models include:
Our diesel engines for 2010 have added Selective Catalytic Reduction (SCR) to the Cummins Aftertreatment System. This change has allowed us to reduce the amount of cooled EGR into the power cylinder, and recalibrate our diesels so they are more responsive to throttle input with equal or better fuel economy than previous models.
Cummins Westport ISL G natural gas engine is your choice for the newest evolution of alternative fuel engine technology, combining all the advantages of clean-burning natural gas with "no compromise" power and torque for urban transit applications.
Cummins is also a leader in hybrid diesel engines. Diesel/electric buses powered by Cummins ISB and ISL engines have completed millions of miles of reliable service throughout the world, from Beijing during the summer Olympics to the mountains of Yosemite National Park.
There's a reason Cummins has been the #1 choice in U.S. urban transit buses since 1998 - our total commitment to delivering reliable power, backed by service and support that you can depend on in a clean and responsible way. Every day.
Cummins reliability and performance is also available in a natural gas option. For information on Cummins natural gas engines for truck and bus applications, visit Cummins Westport.
