ISB6.7 for Urban Bus & Shuttle (EPA 2010)


ISB6.7 for Urban Bus & Shuttle (EPA 2010)

The Cummins ISB engine platform has been a mainstay of transit bus operations around the globe for years.  From China to Europe to the United States, it has a proven record of delivering a low cost of operation with excellent performance and fuel economy.

In 2010, we kept what has made this engine system so successful and enhanced it.  The ISB6.7 features a High Pressure Common Rail (HPCR) fuel injection system that provides constant pressure at every rpm.  This enables multiple injection events per cycle for cleaner, quieter and more complete combustion, so you can expect the ISB6.7 to continue to deliver best-in-class fuel economy.  The proprietary VGT™ Turbocharger has been improved as well for strong throttle response and dependability.

The ISB6.7 EPA 2010 uses the same ECM and software programs as every other Cummins diesel engine.  This commonality simplifies technician training, performance monitoring and service reliability.

Exceptional reliability, smooth acceleration and low operating costs and maintenance intervals make the ISB6.7 an ideal choice.  Ratings include our special hybrid diesel/electric engine.

All backed by the best customer support in the business.
