Environmental and financial benefits of Cummins’ EPA Tier 2 to Tier 4 engine conversion solution

""

The Environmental Protection Agency (EPA) has been aggressively reducing diesel engine emissions over the last 25 years, and Cummins Inc. has committed to developing the technology to meet these requirements. These regulations have been embraced within the oil & gas industry, as the sector continues the journey to reduce its environmental impact. 

The EPA’s latest Tier 4 final emission regulations applicable for oil and gas industry represent a significant step towards further reducing nitrous oxides (NOx) and particulate matter (PM). For example, the Cummins QSK50 Tier 4 for well-servicing produces 45% less nitrous oxides and 80% less particulate matter than its EPA Tier 2 predecessor.

If you are an oilfield service company with an existing fleet of Cummins QSK50 Tier 2 engines, the path to Tier 4 emissions is simpler than you might think. You can transition the Tier 2 engines within your fleet to Tier 4 and enjoy the environmental benefits in an economical way. 

You can simply utilize the Tier 2 to Tier 4 conversion solution on your existing Cummins QSK50 Tier 2 engines at the time of rebuild instead of replacing and scrapping your current engines.

Let’s look at the environmental and economic benefits of converting your Tier 2 engines to certified Tier 4 engines.

Tier 4 final emission standards, in comparison to Tier 3 and Tier 2, represent a significant step towards reducing nitrous oxides (NOx) and particulate matter (PM), key ingredients found in smog. Whether you use the Tier 2 to Tier 4 conversion solution or use brand new Tier 4 engines, your business will still materialize the benefits on engine emission reduction.

Reducing oil and gas sector’s environmental impact beyond engine emissions

Beyond the reduced engine emissions, there is another important environmental benefit of applying the Tier 2 to Tier 4 conversion solution on your Cummins QSK50 engines: reducing scrap metal and equipment. 
The conversion allows you to extend the use of your existing engine and frac rig. For example, you can sustain the longevity of your engine core and save the one or two overhaul lives left in your Tier 2 engines while meeting your emissions goals.

This environmental benefit could be bigger than you think. Scrap metal, when not recycled, fills up the landfills. In the U.S. alone, over 50 million tons of steel is scrapped a year. While 80% to 90% of this gets recycled, the rest accumulates within the landfills. The accumulation of scrap metal in landfills could pollute the nearby soil and water supplies. Scrap metals also create an increased need for mining minerals that can then be refined to metals. This mining and refining is an energy-intensive process.

Lowering the capital expenditures of oilfield service companies

If you already have Cummins Tier 2 engines within your well-servicing equipment, there are two ways to make the transition to Tier 4 engines. 

The first option is to purchase a new Cummins QSK50 Tier 4 engine which offers the same reliability and durability demonstrated by the Cummins QSK50 Tier 2. This is because the selective catalytic reduction (SCR) aftertreatment technology allows Cummins to use the known QSK50 platform while still achieving the lowest diesel emissions in the market. If you opt to go this route, the equipment transition is easy due to the similar footprint and low heat rejection of this certified engine.

Another more economical option, if you have Cummins QSK50 Tier 2 engines, is to upfit to Tier 4 content at the time of rebuild. These conversions are performed at Cummins Master Rebuild Centers by trained and certified technicians.

There are three ways the Tier 2 to Tier 4 conversions can lower your capital expenditures (CapEx).

  1. Lowering the CapEx on new frac rigs. You can extend the life of existing fleets by refurbishing them and utilizing the engine conversion offering. 
  2. Lowering the CapEx on new engines. You get the latest emission certified engines, without the cost of buying a new engine.
  3. Lowering the CapEx on cooling packages. The SCR aftertreatment technology used to achieve Tier 4 emissions allows the engine systems to maintain a low heat rejection which removes the need to invest in a new cooling package for your equipment. 

Generating more revenue using your existing engines and equipment

If you are participating in time-sensitive bids that call for Tier 4 equipment, the longer lead times associated with a new engine purchase could mean lost revenue if your upgraded equipment won’t be ready in time. 

With a Tier 2 to Tier 4 conversion solution, the time to upgrade your equipment could be reduced. And with shorter lead times comes your business' ability to participate in near term bids. 

You can achieve and generate more revenue from your oil and gas equipment with these reduced lead times. 

Decreasing the capital expenditures, helping your business generate more revenue, and reducing your business' environmental impact. These are the three key benefits of the Tier 2 to Tier 4 conversion solution for Cummins QSK50 engines used in oil and gas applications.

STEM Project Unites Children in the UK and Uzbekistan

Zoom call with West Park School and the Children's Home

If you ever doubted the ability of young minds to grasp what many adults would consider complex concepts, then you'll be amazed by the achievements of two groups of young children - one in a school in northern England, and the other 4,000 miles away in an orphanage in Uzbekistan.

With the support of Cummins, children ranging from six to twelve years of age have managed to bridge the language, culture, and time divide. They are collaborating with great success on building a basic electric racing car.

The story begins with a visit by Cummins to Rudmash Export Service, which has been representing Cummins in Tashkent, the capital of Uzbekistan, since 2018.

Rudmash has an impressive list of clients in mining, construction, gas, and power generation.

It is also a highly respected supporter of community initiatives, a key focus for Cummins.

During the visit, Amit Kumar, Cummins' Technical Territory Manager for the Commonwealth of Independent States (CIS) region, mentioned the work he was doing with local schools involving the Greenpower Education Trust in the UK.

Amit suggested that Rudmash might consider introducing local children to the fantastic learning opportunity that comes from building an electric car.

The Rudmash executive team loved the idea and reached out to their friends at the local orphanage (Children’s Home 22), about the proposed connection with children from West Park Academy – a primary school near Cummins' manufacturing plant in Darlington, England.

Speaking through a translator, Rudmash Sales Manager Mr. Mavlonberdi Akhmedov said there was no hesitation from the orphanage. "Everyone was excited about it," he said. "When we showed them pictures of the car, the children's eyes lit up with interest.

"The only issue we encountered was not being able to involve the older children, but I think Amit has something in his mind for them. It will involve a similar collaboration with a UK school on a larger electric car that they can fit in!"

Over in Darlington, teacher Mr. David Fraser and his group of 9 to 11-year-olds were thrilled at the prospect of working with children from another country.

"Before our first session, I showed the children a map of Uzbekistan and explained how the time zones worked," Mr. Fraser said. "Tashkent is four hours ahead of us."

"When they started hearing a different language, they were a little hesitant although still excited. However, towards the end, once they got used to the translation pauses, lots of questions were being asked."

"They adapted very quickly, and every session with the orphanage has become more engaging. The children have greatly benefited from the relationship. It's been a great learning experience."

The car involved in the project is called the Greenpower Goblin G2. It comes as a flat-pack kit including chassis, wheels, steering, disc brakes, a 24V electric motor, and two 12V batteries.

"The project is all about inspiring young children to take an interest in engineering in a fun and innovative way," said Amit Kumar, who earlier this year received special recognition at the North-East England STEM (Science, Technology, Engineering, and Mathematics) Awards for his years of dedication to STEM Education.

"The build introduces children to basic mechanics and electronics and might be the first step on the pathway to a career in engineering or another STEM field.

Mr. Fraser said the children soon started discussing aspects of the car such as frames, brakes, and steering geometry. There was a lively question-and-answer session on different materials that could be used to design and make the car's body. Their last session was about controls and driving.

"There are also other general discussions, as the children are eager to learn more about each other's countries," said Amit, who leads the sessions.

Rudmash service engineer Mr. Abdullayev Shakhzod said the children were enjoying the experience of working in teams.

"It's a fantastic new chapter in the history of a place that has a storied past. It was established in 1942 during the Second World War to care for evacuees from all over Eastern Europe. Children of over 40 different nationalities have been cared for by this children's home.

"The home is named Antonina Pavlovna Khlebushkina after the woman who ran it in the early days. She would be so proud of what is happening there today.

"As the summer vacation times differ in the two countries, the West Park school children have already finished building their cars, while the Uzbekistan car is about 40% complete.

"When the children return from their summer camp in September, they will start the rear axle, motor, and electrical components. Then they can take it for a drive," Amit said.

"Just before their summer term ended, the West Park children conducted a demonstration for their new friends in Tashkent. They set up a track and showcased driving the car on it. It was a great success."

Mr. Akhmedov, speaking through a translator, mentioned that the management team at Rudmash was considering how the project could expand beyond the children's home and into schools and youth organizations throughout Uzbekistan.

Mr. Akhmedov praised Cummins for their support of the project. "They have shown great responsibility at every stage and been very proactive, always striving to ensure things are done right.

"This is just the beginning for these children. It's already motivating them to learn more and develop their skills in broader technical applications.

"I would say that this project is not only important for the children's home but also for our city of Tashkent and the Republic of Uzbekistan, as it is nurturing an educational culture that is highly valuable. I can't thank Amit and Cummins enough."

Amit expressed that it's a privilege to help Cummins inspire young people about engineering and science from an early age.

How is the United States investing in clean energy?

GR hero

Our planet is facing a dire crisis: carbon dioxide concentrations in the atmosphere continue to soar above record highs. If gone unaddressed, the collective stress of climate change will produce an irreparable impact. Our health, energy, water, and food ecosystems are at risk. 

As it stands, there are many long-term effects of climate change. In North America, climate change is forecasted to cause decreasing snowpack in the western mountains. It will also lead to a 5–20% increase in yields of rain-fed agriculture and great intensity of heat waves. In fact, over the last five years, the United States has incurred roughly $120 billion a year in damages as a result of natural disasters caused by extreme weather and climate events.

Beyond natural catastrophes, climatic risks to the United States will have a cascading effect on the country's interconnected ecosystems. Reduced labor and overall economic productivity, and altered crop yields, will disproportionately harm lower-income and marginalized populations. These groups lack the resources to prepare or cope with extreme weather and climate events.

The world is investing in clean energy innovation

Combating the intensifying climate crisis requires a strategic combination of research and development (R&D), innovation, technology — and bold attempts.

Around the globe, countries are investing in clean energy to contribute to a livable planet now and for generations to come. In 2022, the US passed the Inflation Reduction Act, which includes a historic $370 billion investment to address the climate crisis. The Inflation Reduction Act provides tax credits and incentives to power homes, businesses, and communities with clean energy by 2030. The Act will increase investments in the fastest-growing power generation technologies, solar and wind. It will also advance cost-saving clean energy projects and protect two million acres of national forests. These initiatives are in addition to substantial tax credits and rebates offered to families and businesses in the United States.
Consequently, a stronger clean energy economy will contribute to overall economic growth and competition. As a result, there will be millions of new well-paying jobs for Americans to make clean energy.

It is possible to start decarbonizing now

Governmental policy strategies and investments in decarbonization technologies are part of the solution to produce increasingly cheap, dependable, and clean energy.

Strong communities and vibrant economies depend on a healthier planet. As a global power technology leader, Cummins is in a unique position to power customer success by leading during this energy transition. We intent to do so by providing customers with the right technology at the right time, understanding of their needs and applications.

We think of this journey to carbon neutrality in two distinct and complementary ways. First, by innovating zero-emission solutions and introducing them in markets and applications where the infrastructure, development and deployment are ready. Secondly, by advancing internal combustion engines through efficiency improvement and by running them on cleaner alternative fuels for a well-to-wheels solution.

Through Destination Zero, we are advancing low- and no-carbon platforms. This includes diesel and natural gas engines, hybrid, and electric platforms, as well as powertrain components, controls, and related technologies.

Join Cummins in powering a better tomorrow

Cummins environmental sustainability strategy includes goals timed for 2030. Progress toward the reduction of carbon emissions from company plants and facilities — in addition to our products — is in full swing. For more than one hundred years, we have brought technological solutions to market. As a power solutions leader, we will continue to power a more prosperous world for today and tomorrow. Are you ready to consider investing in new power solutions?
