Innovation
Earned its first profit in 1937
Founded in 1919 by Clessie Cummins and W.G. Irwin
Promoted diesels as a reliable source of power
Pioneered the development of diesel engines
Talking points
Founded in 1919, the result of an unlikely partnership between a banker and an inventor, who shared a belief in the power of ideas and a vision for what ingenuity and hard work could achieve.
The men were Clessie Cummins and W.G. Irwin, visionaries who saw the potential and power of the simple diesel engine.
Here is some of the basic history:
Cummins was founded in 1919 in Columbus Indiana, by mechanic Clessie Cummins and investor W. G. Irwin with the financial support from the Irwin family.
As one of the 200 companies with the diesel license, Cummins took the available technology and transformed diesel into a reliable and everyday use of transformation power source.
To promote the diesel engines, Cummins did a lot of creative events to let the world see the reliable power of diesel.
Coast to coast bus tour powered by Cummins diesel engine in 1932 (started in New York and arrived in Los Angeles in 91 hours 10 min and burned only 365 gallons of fuel, which cost $21.90)
Cummins car also ran in the Indianapolis 500 in early 1930s
Clessie also drove a Cummins-powered Auburn car from New York to San Francisco in 1935 on $7.62 worth of fuel
The Irwin family believed in diesel technology and understood the importance of taking the long view – that investing in innovative ideas take time.
It took 18 years before Cummins earned its first profit - in And the rest, as we say, is history.

8. Robust Air Handling System
Single Variable Geometry Turbocharger (VGT)
Simple, elegant design
One sliding nozzle for dynamic airflow control
Provides engine braking
Proven reliability and durability
Incorporates HD bearing system in 2017 PX-7
Modified exhaust manifold interface to improve durability and serviceability
Exhaust Gas Recirculation (EGR)
Steel braided inlets and outlet tubes for improved durability
The Air handling system is lead first and foremost by the Cummins Turbo Technologies Variable Geometry Turbocharger (VGT). This single VGT turbocharger is a simple and elegantly designed turbo that can dynamically adjust the airflow by adjusting a single sliding nozzle for better air/fuel mixing. Additionally, the VGT provides engine braking without the need of incorporating a separate engine brake. The 2017 PX-7 will build upon the proven reliable and durable VGT by incorporating a Heavy-duty bearing system that can be found on our X15 and X12 engines. Additionally, the exhaust manifold and VGT interface has been modified to improve the turbochargers durability and serviceability.
Since 2002, the B-series platform has used exhaust gas recirculation for emissions control. The B-platforms EGR system has seen minor improvements since In 2017, for better durability, the EGR will use steel braided inlets and outlets, and will have updated valves and a single crossover tube.

9. Fuel Systems and Combustion
4 valves per cylinder since 1998
Provides better air flow for optimal combustion recipe
High Pressure Common Rail (HPCR) provides multiple injections per event with 15 years of experience
Reduces noise
Reduces emissions
Improves fuel efficiency
6.7 liters of displacement for increased power density without increasing engine stress
Class leading compression ratio
Since 1984, the B-series platform has used a sleeveless piston design (parent bore). The first major change to the fuel system came with the introduction of 4 valves per cylinder in 1998 which allowed for better air flow and air flow control for a better combustion recipe. This started the directionally correct movement for emissions control without sacrificing fuel economy.
In 2002, the Fuel System and Combustion recipe incorporated High Pressure Common Rail and EGR. This allowed for better NOx control, DPF reduction, without sacrificing fuel economy. Additionally, the multiple injections per combustion event helps reduce emissions, provides smoother operation, and improves fuel economy all while reducing noise.
In 2007, the PX-7 increased its displacement size by 13% by moving from 5.9 liters of displacement to 6.7 liters. By incorporating a deep rib block for improved reliability, durability, thermal management, the PX-7 saw a 24% increase in peak torque, 38% increase in clutch engagement torque and almost 42% increase in overall horsepower.
The class leading compression ratio allows the PX-7 to extract more mechanical energy from diesel fuel, and improve the thermal efficiency of the system, providing better overall fuel economy and aftertreatment management.

10. Fuel Filters by Fleetguard
NanoNet Fuel Filters have been used since 2013
10-13 times more effective at removing 4 micron particulates
Traps and retains contaminants even under real world vibration and flow surge
Protects high pressure injectors from damaging fuel systems
Increases fuel system robustness
Separates water for better fuel protection
In order to provide the class leading compression ratio, the fuel quality needs to be best-in-class in order to prevent any fuel system damage. Since 2013, the PX-7 has utilized Cummins Filtration Fleetguard Fuel Filters with NanoNet media. The NanoNet media provides times more protection compared to a StrataPore filter when removing 4 micron particulates (smaller than a red blood cell). This media does a better job at not only trapping the microns, but holding onto the microns during severe vibration. This protects injectors and improves the overall fuel system robustness.
In 2017, a new stage 1 fuel filter will incorporate water in fuel separation technology to provide even better quality diesel to the fuel system.

11. Electronic Controls Single high capacity ECM (2350)
Common ECM across most diesel on-highway products
Full control authority over the engine and aftertreatment system for optimized performance and improved engine lamp strategy.
Incorporates Connected Solutions
The single high capacity engine control module (ECM) on the PX-7 is common across most (PX-9, ISX12, X15) on-highway diesel platforms. ECM 2350 fully incorporates control of both the engine aftertreatment system for better performance and improved driver dash-lamp notification.
Additionally, the PX-7 will be capable of using Cummins Connected Solutions through a telematics provider.
Connected Diagnostics provides instantaneous fault code analysis and sends recommendations to owners / fleet managers for better decision making.
Connected Calibrations allows for new engine calibrations to be sent and saved in the ECM until the driver stops, and accepts the change… this can ensure that even the most remote vehicle (with access to telematics data) is operating with the most up-to-date engine calibration.
Connected Tuning allows for the adjustment of specific engine parameters without the need of stopping and having the vehicle serviced. If the Px-7 vehicle changes routes and you want more control over cruise or pedal speeds, connected tuning allows you to remotely send an updated calibration to the engine, and all that is needed is a driver to select “accept” when the vehicle is stopped.

12. Single Module Aftertreatment
Customer voice-driven design
Combines high-efficiency SCR, an enhanced dosing unit and a high capacity DPF into a single flow-through unit.
MidRange System features:
Up to 70% reduction in space claim
Up to 30% reduction in weight
Enhanced thermal and fuel efficiency
Building off over 10 years of aftertreatment experience, the 2017 PX-7 will use the new, Single Module Aftertreatment, from Cummins Emission Solutions. By consolidating the 2010 and 2013 aftertreatment system (DPF, Decomposition Tube, and SCR catalyst) into a single flow through unit, the PX-7 aftertreatment will see up to a 70% reduction in space claim (volume) and up to 30% reduction in weight. This flow-through design, either side-in-side out, or end-in-end-out, provide better thermal management and fuel efficiency without increasing backpressure.

Any rating from horsepower requires only a calibration change in order to move from one horsepower/torque rating to another. These “Efficiency” ratings provide up to 7% fuel economy gains compared to the 2016 PX-7.
When moving from 260 horsepower to horsepower, a new turbocharger, new pistons and fuel injectors, and a larger single-module aftertreatment is needed. Therefore it is crucial that during the spec’ing process, you choose the horsepower/torque level optimized to for your objective and duty cycle.
