Cummins Inc. (NYSE: CMI) next-generation X12 engine will set new industry standards for performance in fire and emergency apparatus. To be revealed this week at the Fire Department Instructors Conference (FDIC) International, Booth 5429, the X12 has the highest power-to-weight ratio of any engine in the 10-to-16-liter class. Rated at up to 500 hp, it weighs 400 lb to 600 lb less than other medium-bore engines. This means less weight on the front axle, which, combined with its compact configuration, enables greater flexibility in cab design.

The innovative architecture of the X12 results in a remarkably low engine weight, at only 2,050 lb. A sculptured block design allows unnecessary mass to be removed while retaining high rigidity. Substantial weight savings are also achieved by the use of high-strength composite materials for the oil pan and valve cover.

"During the design process for the X12, we evaluated every opportunity to reduce size and lower weight, achieving this with no compromise to structural strength so that this next-generation 12-liter comes with all the durability associated with a Cummins Heavy-Duty engine," said Jim Fier, Cummins Vice President - Engineering. "We are really excited about how the X12 provides OEM partners with a lighter weight, rugged and powerful engine that not only provides great performance, it allows for more critical equipment to be transported to the scene."

Additional integration and weight savings were realized with the new Single Module(TM) aftertreatment, designed by Cummins Emission Solutions to be up to 40 percent lighter and up to 60 percent smaller than current aftertreatment designs. The compact design is easier to install and service, and the exceptional thermal efficiency of the Diesel Particulate Filter (DPF) requires fewer regenerations. Integral to the system are the latest Cummins Diesel Exhaust Fluid (DEF) doser and a new compact mixer design, resulting in a more precise spray pattern, to enhance X12 reliability while minimizing DEF consumption.

The next-generation X12 is available with ratings that range from 455 hp to 500 hp, and was designed to meet the maximum performance needs of fire and emergency apparatus. With 1695 lb-ft maximum torque maintained from 1000 to 1300 rpm, the X12 provides great launching ability and highly responsive overall vehicle performance. As on all Cummins-powered emergency vehicle engines, calibrations maintain maximum performance even if an emissions-related fault occurs or during aftertreatment system regeneration. Also, when the X12 is specified with an Onan(R) generator, the Cummins service network is the single source for maintenance, parts and service for both the engine and generator.

Customer-focused innovations on the X12 include a Single-Cam In-Head (SCIH) design with a roller valve train and high-efficiency intake ports, to minimize frictional losses and improve fuel economy. The cylinder architecture minimizes oil consumption, and fully integrated return paths send oil flowing back through the filter, reducing degradation. With over 3 million Cummins VGT(R) Turbochargers in service today, the Cummins VGT Turbocharger sets the industry standard for reliability and durability. Enhancements to this proven design boost transient response and, in combination with an integrated low-weight engine brake, provide strong engine braking at lower rpm. The XPI fuel system, derived from the X15 engine, is scaled in size to match the 12-liter platform while retaining all the same robust characteristics. Additionally, the X12 shares common components with the Cummins X15, including the Single Module aftertreatment system, oil filters and fuel filters, and the compact design l

As thousands of firefighters from around the country (and some from around the world) packed buses outside the Indianapolis Convention Center to head to Hands-On-Training sites, FDIC International 2017 opened its preconference workshop doors at 8 a.m. to inquisitive fire students and an equally eager, highly knowledgeable cadre of instructors.

Among these instructors was first-time presenter and 33-year fire service veteran Paul Jockimo, assistant chief of the Somers (NY) Fire District as well as a critical stress incident management/peer support provider, coordinator, and instructor.

"On June 22nd, 1997, I survived a fire that killed my lieutenant. Aside from the operations at the fire that morning, I was at the center of the planning and preparation for all that followed," Jockimo said.

"While cities like New York, Los Angeles, and Chicago may go through this often, most agencies do not. Immediately, I began studying line-of-duty deaths [LODDs] and the aftermath that the organizations and families have to endure. I began writing short lessons on the subject that would evolve soon, into one- and two-day classes."

Here, Jockimo discusses the differences between firefighter suicide and line-of-duty deaths:

Jockimo continued, "For the past 20 years, LODDs have been my 'specialty.' I've worked with dozens of agencies across the country during and following these events as well as having taught countless others in preparation as well.

"Yes, I was involved in the Worcester [MA] Fire in '99, the World Trade Center, and Newtown. But so what? Many were."

Next, Jockimo discusses the importance of developing a fire department policy for registering a line-of-duty death:

"Every high-impact event—be it an LODD, a suicide, or an off-duty death—leaves a mark. While everyone rushes to help during that first week, I often work with them for months or even years after. Is it tough? Yes, at times. But this is my way of giving back, part of that which has been given to me."

Here, Jockimo discusses the varying dynamics of dealing with a line-of-duty death in your department and at home with your family:

He concluded, "This is my first FDIC. It is an honor, beyond description, to be able to teach, walk and talk among the legends of the fire service, who are in the purest sense....family.

"In October, I will be one of 50 firefighters (out of the 1.4 million in the United States) that will be profiled in the book American Firefighter, being put out by the NFFF. While it is an amazing honor, my hope for it, is that it may serve as but another platform with which to help others. In the big picture, that is what I hope everyone at FDIC takes away.....a greater drive to help others."
