Cummins ISB is a mainstay of transit bus operations around the globe. From Beijing to London to San Francisco, the ISB provides a low cost of operation with excellent performance and fuel economy. Updates include an increase in displacement from 5.9 to 6.7 liters (+13%). The result is an ISB that accelerates smoother and runs quietly, with greater power, efficiency and performance than ever before. The VG Turbo is standard on every ISB engine, regardless of horsepower and includes electric actuation for more precise airflow management and faster response.

The ISB for 2007 runs cleaner, delivers better performance and maintains fuel economy comparable to EPA '02 compliant and certified engines. Ratings range from 200-325 hp. Plus, with an integrated compression brake as standard equipment, it even stops better. How did we make so many improvements and still meet stringent emissions controls? With a totally integrated system that includes our proven cooled-EGR subsystem, a High Pressure Common Rail fuel injection system, our patented VG Turbo, Cummins Particulate Filter and a crankcase ventilation system.

The Cummins ISB has a long reputation as the most fuel efficient engine in the motorhome industry. The ISB utilizes the Cummins Variable Geometry Turbocharger (VG Turbo) and High Pressure Common Rail (HPCR) fuel system to produce outstanding driveability, integrated exhaust braking and, arguably, the quietest diesel engine in a motorhome today. Its industry-leading fuel economy, extended oil change intervals and minimal maintenance requirements also make the ISB the low-cost-of-ownership leader in its class.

Whether you're rushing paramedics to an accident scene or responding to a brush fire, you can count on Cummins ISB. Every call. Every time. The 2007 ISB combines increased displacement (5.9 liters to 6.7 liters) and High Pressure Common Rail fuel injection with our patented Variable Geometry Turbo to deliver stronger performance at every rpm. Multiple injection events per cycle also make the ISB run extremely quiet.
