ISC for Truck (EPA 07)The ISC for 2007 runs cleaner, delivers superior performance and maintains fuel economy comparable to EPA '02 compliant and certified engines. Ratings range from 240-330 hp. Add the optional compression brake, and it even stops better. How did we make these improvements and still meet stringent emissions controls? With a totally integrated system that includes our proven cooled-EGR subsystem, enhanced High Pressure Common Rail fuel injection system, our patented VG Turbo, Cummins Particulate Filter and a crankcase ventilation system.

And that's just the start of all the features the ISC has to help your vehicles, and your business, run smoother.

The ISC is also designed to keep your maintenance to a minimum and your productivity in overdrive.

All backed by the best customer support in the business.

The superior performance of the ISC comes from a constant flow of high-pressure fuel, injected with precise timing for optimum burn efficiency. Regardless of engine speed, the pressure inside the High Pressure Common Rail fuel system does not fluctuate. An increased number of injection events per cycle results in an ISC that runs both stronger and more efficiently than ever before.
