The ISL For 2007 runs cleaner, delivers superior performance and maintains fuel economy comparable to EPA ’02 compliant and certified engines. 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, a 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 ISL has to help your vehicles, and your business, run smoother.

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

• Enhanced High Pressure Common Rail Fuel System – Delivers optimum balance of performance, emissions control and fuel economy across the entire operating range.
• Full-Authority Electronic Controls – Higher microprocessor capacity and speed for optimum control of the engine and aftertreatment.
• Cooled Exhaust Gas Recirculation – Lowers combustion temperatures for reduced emissions and optimized mpg.
• Variable Geometry Turbocharger – Enhanced response and control with electric actuation for infinite adjustment, providing exact boost across the operating range. Sliding-nozzle design increases reliability, durability.
• Cummins Particulate Filter – Fully integrated for uncompromising performance, reliability. Reduces particulate matter 90%.
