Cummins ISL8.9 Engine Overivew
ISL FOR FIRE & EMERGENCY (EPA 07)
The two things that matter most in a fire or emergency vehicle are response time and reliability. So we built the 2007 ISL with superior performance and exceptional dependability. And in the process, we also made it run cleaner.
How did we make these improvements and still meet stringent emissions controls? The ISL is designed as a totally integrated system that 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 ISL has to help your fire and emergency vehicles get ready to roll on a moment's notice, every time.
The ISL is also designed to keep your budget from going up in smoke, with long maintenance intervals and excellent fuel economy. Ratings range from 345-425 hp.
