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.

When you start looking at motorhomes with a living room bigger than most condos, one thing is an absolute necessity: A Cummins ISM 500 or ISM 450, with all the power, smoothness and reliability to glide effortlessly up the peaks and through the valleys, even when towing a boat, car or trailer.

With hundreds of millions of miles of operation in bus fleets worldwide, Cummins ISM has earned its reputation for reliability and durability. Key technologies like the cooled-EGR subsystem, VG Turbo, and electronic fuel injection have been used on the ISM since 2002. Even the newest emissions control technology, particulate filtration, is not new. Thousands of Cummins-powered buses equipped with Cummins Particulate Filters are in operation in North America today. Every Cummins system is designed with performance and reliability in mind.

Cummins ISM continues to lead the way for heavy-duty diesels in its class. Thoroughly tested and proven to meet Cummins rigorous durability standards, the ISM satisfies the latest emissions requirements without expensive aftertreatment or special fuels. The bottom line: You win. With its proven reliability, impressive fuel savings and electronics that integrate all engine functions for low cost of operation, Cummins ISM is clearly ahead of the competition.

Every Advantage. For reliability, low operating costs and strong performance, Cummins ISM can’t be beat. It has one of the highest power-to-weight ratios in its class. An advanced fuel injection system and the patented Variable Geometry Turbocharger (VG Turbo) result in superior performance over every terrain, in any condition. Cummins ISM for EPA 2007 has comparable fuel economy to the previous model, so you get added savings every mile.

In every aspect of heavy duty performance this engine has set benchmark standards for fuel efficiency, driveability and reliability. The ISMe has a long standing reputation for excellent transient response and higher overall refinement, enabling it out perform larger engines. Structurally, the ISMe is at the forefront of heavy-duty design with a life-to-overhaul goal of one million km. Yet despite all this inbuilt strength the engine weighs only 940 kg, offering a substantial payload advantage.

Cummins ISV5.0 goes beyond the traditional diesel attributes of horsepower, torque, reliability and durability to deliver the next dimension of performance. Cummins global diesel design expertise has combined advanced materials, the latest High Pressure Common Rail (HPCR) fuel system, Cummins VGT Turbocharger and Cummins emission control technology to produce an extraordinarily clean, quiet and fuel-efficient V8 diesel engine. The ISV5.0 is ideally suited for pickup and delivery vehicles, school buses, light- and medium-duty trucks and motorhomes.

Cummins met the 2007 emissions standards with a totally integrated system from air intake to exhaust aftertreatment. It includes our proven cooled-EGR subsystem, an electrically actuated VG Turbo, a proprietary Cummins Particulate Filter and a crankcase ventilation system with a coalescing filter - all managed by a single Electronic Control Module. Every element has been designed and manufactured to optimize performance and minimize maintenance. Ratings range from 385-600 hp.

For superior performance, exceptional fuel efficiency and incredibly strong braking power, ultra-luxury motorhome owners choose Cummins ISX. Every time. With ratings from 525-600 horsepower, the ISX delivers uncompromising performance for towing heavy loads and climbing steep mountain grades. Standard features include the patented Variable Geometry Turbocharger (VG Turbo), now with electric actuation for enhanced engine response at every rpm. While the standard Intebrake system produces over 600 braking horsepower for superior driver control on downhill slopes.

Cummins ISX handles the largest fire equipment with ease.  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.
