ISC for Fire & Emergency (EPA 07)

Power 260 - 360 hp
194 - 268 kW
Torque 800 - 1050 lb-ft
1085 - 1424 N•m
Certification EPA 2007


Mid-size equipment is the backbone of every fire department, from EMT vehicles to hook and ladder trucks. The 2007 ISC is the best power for this equipment, designed to run stronger than ever with exceptional dependability. Not only does it have more powerful performance, it is quiet, making communications in the cab easier.

The totally integrated ISC design includes our proven cooled-EGR subsystem, a High Pressure Common Rail fuel injection system, patented VG Turbo, Cummins Particulate Filter and a crankcase ventilation system. Add the optional compression brake, and it even stops better with more than 330 braking hp.

And that's just the start of all the features the ISC has to help your fire and emergency vehicles on call, every minute of every day.

The ISC is also designed to keep operating costs in check, with long maintenance intervals and excellent fuel economy. Ratings range from 260-360 hp.

Heavy-duty components such as articulated-steel-top pistons and roller camshaft followers are standard, along with a self-tensioning belt drive system to increase belt life. A high-efficiency lube cooler lowers oil temperatures and improves lubrication. Put all that together with Six Sigma design practices, and you've got an engine that is built to run long and strong, in every type of fire apparatus and emergency vehicle.

  • 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%.
  • Crankcase Ventilation System - coalescing filter only needs replacement every 3rd to 4th oil change.
  • Low Maintenance - Long oil change intervals maintained. Cummins Particulate Filter will go 200,000-400,000 miles (320,000-640,000 km) in a typical duty cycle for most vehicles before it needs cleaning.
  • Heavy-Duty Features - Replaceable wet liners, roller followers, by-pass oil filtration, targeted piston cooling, robust valve train and more.
