Certification EPA 2007


Heavy-duty fire equipment puts a heavier demand on your engine. That's where the 2007 ISM shines. Not only is it designed to run stronger than ever with an improved VG Turbo, it has one of the highest power-to-weight ratios in its class. So you get superior performance with improved transient response for quicker response times. And, Cummins ISM provides high pumping pressure at low rpm to do battle with a four-alarm blaze. All good reasons why the ISM should remain America's #1 choice for custom-built fire apparatus.

Every element in our integrated design is manufactured within the Cummins family. That includes features like our proven cooled-EGR subsystem, a High Pressure Common Rail fuel injection system, patented VG Turbo, Cummins Particulate Filter and a crankcase ventilation system.

Even the C Brake™ by Jacobs®* is custom designed to deliver up to 345 braking horsepower in the 2007 ISM.

Cummins ISM for 2007 is designed for years of reliable service with an absolute minimum of maintenance. Ratings range from 365 to 500 hp, to match the performance needs of every type of heavy-duty fire apparatus.

The ISM for 2007 will deliver the same kind of durable, reliable, powerful performance you've come to expect.

The patented VG Turbo constantly adjusts airflow to reduce turbo lag, improve transient response and increase vehicle performance. And now, electric actuation gives faster response.

*Rating does not include a Cummins Particulate Filter
**Rating available with or without a Cummins Particulate Filter
  • Cummins Particulate Filter - Fully integrated for uncompromising performance, reliability. Reduces particulate matter 90%.
  • Crankcase Ventilation System - coalescing filter only needs replacement every 3rd to 4th oil changes.
  • Fully Integrated Electronic Controls - A single ECM controls engine and aftertreatment. Also coordinates interaction with transmission, ABS, engine brake, cooling fan and more.
  • Variable Geometry Turbocharger - Enhanced response and control with electric actuation for infinite adjustment, providing exact boost for any rpm. Sliding-nozzle design increases reliability, durability.
  • High-Pressure Fuel Injection System - For cleaner, more complete combustion.
  • Cooled Exhaust Gas Recirculation - Lowers combustion temperatures for reduced emissions and optimized mpg.

Maintenance intervals for the lubrication system on the 2007 ISM will not change.

See your Owner's Manual for every detail. And when it's time for maintenance, be sure to visit your Cummins distributor for fast, accurate service.
