| The ISB For 2007 runs cleaner, delivers better performance and maintains fuel economy comparable to EPA '02 compliant and certified engines. Plus, with the VGT 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. And these are just a starting list of some of the features. The ISB offers a choice of truck engines from 200 hp to 325 hp and a maximum 750 lb-ft of peak torque. These engines have the highest power-to-weight ratio in their class. |  |
