Power-to-weight equals more than just productivity

Operating vocational trucks is all about getting the job done as reliably, quickly and productively as possible. Nailing the power-to-weight ratio on the sweet spot can have a major impact on not just your equipment’s productivity but its longevity and your bottom line as well. There are a number of factors that come into play when spec’ing a vocational vehicle that help ensure that performance capability matches the duty cycle and jobsite conditions. It starts with choosing an engine that has the ideal power-to-weight ratio and pairing it with the correct transmission and tires, based on the most demanding aspects of its operating usage. 

Weighing In 

Regardless of whether you are spec’ing a dump, refuse truck, mixer or bulk hauler, there are substantial advantages to using a lighter-weight engine – provided it has sufficient power. In applications which typically gross out, a lighter weight engine gives you the opportunity to carry more payload (equal to the weight savings). Less weight on the front axle also reduces stress and wear over time, reducing maintenance costs. The weight savings/increased payload can be as much as 630 lbs. per trip in a vehicle, when switching from a Cummins ISX12 to a 2021 X12™. 

Productivity Pays 

Having the right spec with a lighter engine pays big dividends, regardless of the business you are in or the type of vocational vehicles in your fleet. For instance: 

Refuse – A lighter engine with the proper spec can accelerate faster between stops and carry more waste, potentially resulting in greater coverage per vehicle on its daily routes. Depending on the size of the municipality being served, it could reduce both the number of vehicles and manpower needed for total coverage. It can also save money at landfills where there is a per-vehicle charge in addition to the cost of the waste being dumped. 

Mixers – The key is to spec the vehicle at maximum load, making sure that it adheres to local load limits for highways, bridges and roadways throughout the area. Some mixers have three drive axles, to help provide the traction needed to negotiate muddy, difficult worksites with steep inclines. 

Dump Trucks – Similar to mixers, construction dumps can have highly variable load weights and taxing work environments. For increased equipment longevity, operators should be trained in proper loading (between the axles with the initial loading, moving over the axles at the end). 

Bulk Haulers – Tractor trailers are a different configuration and have greater flexibility with regards to load distribution. The fifth wheel can be shifted forward to put more weight on the drive axle, or back to put greater load on the rear axles. When spec’ing the tractor, you can often choose a smaller displacement engine (such as a 12-liter rather than a 13-liter), which will allow for a shorter frame rail and wheelbase measured as BBC. The combined weight savings can be as much as 1,000 lbs. in the front end, and an equivalent increase in payload while staying under the 80,000-lb GVW limit. (The typical load pattern for a tractor trailer is 12K steer axle, 34K tandem axle and 34K trailer). 

Additional Considerations

When spec’ing a vocational vehicle, it is critical to take into consideration seasonal additions like a snowplow attachment, pumps, or any feature that requires an extended front bumper or puts extra weight on the drive axle. When spec’ing an engine for weight savings, it is critical to choose a horsepower/torque rating that meets the highest regular power demand in your duty cycle, and to pair it with an appropriate transmission, ensuring that you get the highest productivity, exceptional reliability and longevity plus driver-pleasing performance. All at a reduced powertrain weight. Cummins PowerSpec can guide you through the entire process

Natural gas engines from Cummins can offer considerable longevity and reliability when properly maintained – so much so they are lasting decades and counting. 

Between 2008 and 2009, more than 3,730 Cummins B Gas Plus natural gas engines were procured through OEM partners Tata Motors and Ashok Leyland and delivered to the National Capital Region of India. Deployed into the Delhi transport Corporation’s (DTC) transit bus fleet, nearly 15 years later, the engines remain in service. To date, the buses have travelled approximately 5.4 billion kilometers – yes, billion – over the last 15 years.

“Cummins engines are sought after globally for their world-class reliability and durability,” explained Puneet Jhawar, General Manager – Natural Gas. “We have learned a lot from our experience in India, among other countries adopting natural gas engines, learnings that have influenced our next generation of engines.”

Last year, Cummins announced the B6.7 natural gas engine will be available in India. Built for school buses, shuttles, and medium-duty trucks, the B6.7N boasts up to 240 hp/560 lbs-ft torque.

As the most mature, proven, and least disruptive alternative power technology available today, natural gas engines offer range flexibility and deliver a similar power, performance, and driving experience as diesel engines. Cummins natural gas engines help fleets reduced their overall environmental impact without significantly increasing the cost of operation or sacrificing performance or uptime.

The power of Cummins’ natural gas engines was on display at the India Auto Expo in Greater Noida Uttar Pradesh, India this month.

Green travel is on track: Our fuel cell systems are powering the world’s first 100%-hydrogen passenger train fleet

Holiday vacation plans? Visit us in Europe where we’re powering the world’s first fleet of hydrogen trains. The Alstom Coradia iLint trains are outfitted with Cummins fuel cell systems and run on the world’s first 100%-hydrogen-powered passenger train route. The trains convert hydrogen fuel into energy and turn existing, non-electrified infrastructure into zero-emission rail lines. These trains emit only steam and condensed water while in service and operate with low noise levels that improve both operator and passenger comfort.

The hydrogen fuel cell systems used in the trains are assembled at Cummins’ Hydrogen Fuel Cell Systems Production Center in Herten, Germany. The facility was fully operational in 2022, enabling accelerated adoption of hydrogen technologies across Europe and the globe.

North America? Check. Europe? Check. We’ve expanded our New Power footprint across the globe

This year, we drove the green hydrogen economy forward across the globe by supporting new infrastructure projects and advancing government decarbonization goals.

We have broken ground on our new gigawatt PEM electrolyzer manufacturing plant in Guadalajara, Castilla-La Mancha, Spain. Construction is scheduled to be complete by the end of 2023. The 200,000 sq. ft. facility will have the capacity to produce 500MW per year, scalable to more than 1GW per year.

Our Oevel, Belgium electrolyzer manufacturing facility expanded its capacity to 1GW thanks to the Important Project of Common European Interest (IPCEI) Hy2Tech program. IPCEI will help Cummins develop a new generation of PEM electrolyzer cell stacks to power large-scale hydrogen production systems. Operation began at our new Hydrogen Fuel Cell Systems Production Center in Herten, Germany this year, which further enables the adoption of hydrogen technologies across Europe. 

We expanded our Mississauga, Ontario, Canada campus by adding a third facility dedicated to hydrogen technology. The new facility accommodates the company’s growing staff, hydrogen production capacity and new product development, putting Cummins in a better position to support the developing hydrogen market in North America.

The wait is over - our electrified powertrains made their official debut

We unveiled the Meritor 17Xe ePowertrain integrated with a Cummins battery system. The 17Xe is designed for heavy-duty trucks with the capacity to support 44 tons of gross combined weight. The assembly also features Cummins’ new lithium iron phosphate (LFP) battery pack. 

Our clean drivetrain options offer performance and packaging advantages for diverse applications across the globe.

Electrolyzers are stateside: We’re starting production in the U.S.

We announced that we'll begin producing electrolyzers in the U.S. for the first time at our Fridley, Minnesota facility. To drive the domestic green hydrogen economy forward, we'll start at 500 megawatts (MW) of manufacturing capacity annually, scalable to 1 gigawatt (GW) in the future.

recipients holding trophies

Cummins Inc. (NYSE:CMI) announced the 2022 recipients of the company’s most prestigious technical award, the Julius Perr Innovation award. Now in its 23rd year, the award recognizes employees who demonstrated excellence in innovation and technology by developing significant intellectual property for our products.

This year’s recipients are Cummins employees Richard Ancimer, Krishna Kamasamudram, Ashok Kumar, Guoqiang Li, Tim Proctor, Michael Wilson, and Aleksey Yezerets. Acknowledgement also goes to Neal Currier, Ed Hodzen, and Vivek Sujan.

ABOUT THE INNOVATIONS

The first winning patents relate to the mitigation of sulfur accumulation on a selective reduction catalyst (SCR).

Ancimer, Currier, Kamasamudram, Kumar, and Yezerets developed methodologies to not only monitor this accumulation of sulfur but regenerate the catalysts faster, and at lower temperatures, through the synchronization of engine operating conditions during regeneration. Their work is employed on Cummins products, such as Euro IV/V/VI, EPA 2010, Tier IV, and in regions high sulfur fuel, and will likely continue playing a role in meeting future emission regulations.

Wilson developed a different approach targeted for the service channel in areas with high sulfur fuel, particularly the Euro V products in South America.  A key feature of his invention involves the deactivation of cylinders, and his work has been cited numerous times by non-Cummins patents.

For second winning technology, Hodzen, Li, Proctor, and Sujan invented the SmartTorque2 (ST2) feature, which is part of the award-winning Eaton Cummins SmartAdvantageTM  Powertrain. This feature automatically senses a variety of factors, such as grade and weight, and selects the optimum torque for performance and fuel economy. The invention was first in production in 2013 and has been a standard offering of the X15 product since 2017.

ABOUT THE AWARDS

This award was created to honor Dr. Julius Perr, who retired from Cummins in 1997 as Vice President - Fuel Systems.  Dr. Perr, who passed away in 2005, joined Cummins in 1958 after fleeing Communist Hungary.  He made Columbus, Indiana (USA) home and began a 41-year career as a Cummins engineer and leader.  In his lifetime, he was named the inventor or co-inventor of 186 granted patents and remains an inspiration to many in our industry.

This article was authored by Chuck McClaugherty, Bear Electric, a Cummins Authorized Dealer.

Smart phones, smart TVs, virtual assistants, smart thermostats, smart locks and doorbells. Our homes are now filled with smart devices. Unfortunately, most of them become useless without power to run or recharge. This is why homeowners should consider installing one smart device above all other: a home standby generator. 

As a Cummins Authorized Dealer, I install a lot of Cummins QuietConnect™ home standby generators throughout Oregon. With increasingly severe weather, rolling blackouts, and aging power grids, I can tell you without a doubt a backup generator is a worthwhile investment. 

The best part of owning one of these smart devices? You don’t have to tell it when to turn on and off. It does it automatically. 

In a nutshell, here’s the process:

When we install a Cummins home standby generator, we also install a Cummins automatic transfer switch. This transfer switch constantly monitors the electric utility power coming into the home. If it detects a break in service, it will automatically disconnect the home from the electric utility line in a split second and turn on the Cummins generator to power the home instead. The generator is fed either by a natural gas line or by a propane tank.

While the Cummins generator is powering the home, the transfer switch will continue to monitor the electric utility line. Once it detects that power has been restored, it’ll automatically disconnect the generator from the home’s electrical system and reconnect the electric utility.

You don’t have to do anything. Nada. Zilch. The generator and the transfer switch do all the work. In some cases, you may not even realize there’s a power outage until you look out the window and see all your neighbor’s houses are dark.

Just as critical as having a Cummins Authorized Dealer professionally install your backup generator and transfer switch is making sure you choose the right size generator for your home. If it’s too small, the load won’t be able to power everything in the house. If it’s too big, you’ll consume extra natural gas or propane when you use it.

The easiest way to make sure you select the right size generator is to have your dealer do it for you. But if you want to get a feel for how much generator you’re going to need, Cummins has an excellent blog post on calculating the generator wattage you need or you can use the generator size calculator at Cummins.com.

We live in a world full of smart devices. Make sure you can keep yours up and running during power outages with a Cummins QuietConnect home standby generator.
