Cummins Every Time - Fire & Emergency

Cummins ISX handles the largest fire equipment with ease. Every time.

Its unique dual overhead camshaft design delivers high performance and exceptional braking. The first cam drives high-pressure fuel injection for clean, responsive power. The second cam includes a dedicated set of lobes for the operation of the integrated engine brake, in addition to operating the intake and exhaust valves. High-pressure fuel injection gives the ISX cleaner, more complete combustion. The VG Turbo now has electric actuation to provide the exact amount of boost needed at every engine speed.

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

Cummins ISX for 2007 is designed for years of reliable service with an absolute minimum of maintenance. The 2007 ISX is offered with a 525-hp rating.

Dual Overhead Camshafts - One camshaft drives high-pressure fuel injection for clean, responsive power. The second camshaft operates the intake and exhaust valves, with dedicated lobes for the integrated engine brake.
Cummins Intebrake™ - Up to 600 braking horsepower for greater vehicle control, reduced service brake wear.
Fully Integrated Electronic Controls - A single ECM (Electronic Control Module) controls the engine and aftertreatment. Also coordinates interaction with the transmission, ABS, engine brake, cooling fan and more.
Variable Geometry Turbocharger - Enhanced response and control with electric actuation for infinite adjustment, providing exact boost at any rpm. Sliding-nozzle design increases reliability, durability.
Cooled Exhaust Gas Recirculation - Lowers combustion temperatures for reduced emissions and optimized mpg.
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.
Patented Mid-Stop Cylinder Liners - Robust design allows for variations in coolant chemistry.
High-Pressure Fuel Injection System - For cleaner, more complete combustion.
Low Maintenance - Go up to 15,000 miles (24,000 km) between oil drains and filter changes.

Maintenance intervals for the lubrication system on the 2007 ISX 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.
