Reduce Carbon Emissions Utilizing Familiar IC Engine Technology

Due to the fact that much of the focus on reducing carbon emissions is focused on rechargeable electric vehicles (BEVs) and hydrogen electric vehicles, the current reality remains out of reach for many customers for a variety of reasons, ranging from initial cost to affordable charging or refueling. duty cycle, etc. It will take a significant amount of time before these technologies become viable for a larger percentage of customers. Customers still need to consider key business metrics such as total cost of ownership and the end result when purchasing large equipment.

Electric vehicles promise, and costs and infrastructure will continue to improve, but internal combustion engines can provide a path to zero emissions. There are still opportunities to significantly reduce carbon emissions using an internal combustion engine. “We know our planet can’t wait for the perfect solution to happen,” says Shrikant Padmanabhan, president of Cummins Engines. “Instead, our approach should be a combination of using zero-emission power where it is available, and using cleaner, low-carbon energy where it is not. This is what I call the continuous improvement of the beats of deferred perfection. Going to zero is not a light switching event. All we can do to start cutting carbon today is win for the planet. ”

Decisions tailored to the customer’s situation

“Some users may be able to quickly switch to battery electric solutions and electric fuel cell solutions that we produce as part of our new energy business,” says Podmanabhan. “But for others, they just can’t go today.” Each end user must assess the economy, power and range requirements, including refueling needs. “In addition, they need to address infrastructure issues, regional resource needs, outcomes, total cost of ownership and technology constraints that make each decarbonisation challenge unique. It’s difficult, and there is no single solution. ”

To help customers who can’t immediately switch to electrical solutions from batteries and fuel cells, Cummins presents a line of agnostic platforms for internal combustion engines designed to help fleets move to zero emissions. “These unified platforms will use engine blocks and key components that have a common architecture, but will be optimized for different types of low-carbon fuels,” says Podmanabhan. “The basic concept is that there will be similar components under the head gasket. There will be different components for different fuels above the head gasket. ”Hydrogen internal combustion engines provide a low-cost carbon-free solution for high load factors and high utilization, where battery-powered electrical solutions cannot meet operational requirements and fuel cells are still economically unprofitable.Cummins

Cummins is rapidly building up these engine offerings. “We have already announced 15-liter natural gas and hydrogen engines for heavy-duty and long-haul markets,” Podmanabhan said. “Soon we will be offering gasoline, propane and hydrogen internal combustion engines designed for mid-level professional and transit applications.”

Cummins plans to introduce a full range of solutions, from advanced diesel engines to batteries or hydrogen electric ones that meet the needs of any customer. “Our current products include advanced diesel and natural gas engines,” said Jonathan White, vice president of technology. “Over the years, we have continued to implement these technologies to make them cleaner and more efficient. Today, our line of diesel products saves more than 20 percent more fuel than 15 years ago. ” And this work continues. “Our engineers are working to make internal combustion engines even more efficient by integrating components into complete transmission solutions. These components include filtration, after-cleaning, turbochargers, fuel systems, electronic control systems, air handling systems, automated transmissions and telematics. ”

Natural gas has been the main focus for reducing emissions in internal combustion engines. “Our natural gas engines have reduced NOx emissions by more than 90 percent compared to current EPA requirements,” White notes. “When powered by renewable natural gas, they can provide negative greenhouse gas emissions while providing the same power and reliability as diesel. Think about the impact on the planet if more trucks ran on renewable natural gas. ”

Smooth transition to emission reductions

Cummins ’unified technology platforms will make it easier for fleets to transition to zero carbon emissions today. The engines expand the portfolio of existing B, L and X series engine platforms. “In addition to our 15-liter natural gas and hydrogen products, we add gasoline, propane and hydrogen to our B6.7 portfolio, complementing our current diesel and natural gas products. “White says. “These fuel-independent engine platforms will have a series of engine versions derived from a common base engine, meaning they have a high degree of detail commonality. The bottom of the engine looks the same, and the top can hold different types of fuel. Each version of the engine can run on a different fuel.

Many options are available. “Today you can already order gas versions of multiple Cummins engines,” White says. “These nearly zero-emission natural gas engines can run on compressed or liquid natural gas. In addition to natural gas, we develop engines that run on propane and have a high degree of commonality of parts with our engines on natural gas and diesel. Finally, we plan to add hydrogen-powered engines. Our tests of internal combustion engines running on hydrogen fuel are going well. “

A fuel-independent approach allows end users to choose the right transmission for their use with minimal CO2 exposure. “No matter what type of fuel the fleet chooses, these new, fuel-independent platforms provide the perfect combination of reliability and reduced or zero carbon emissions,” White says. “Today’s digital and connected technologies allow us to extract information specific to different engine life cycles and use them to develop robust agnostic platforms.”

Common architecture advantages of OEMs and service technicians

The commonality of details is a key advantage of this new technological approach. “Our engineers want to develop products that reduce carbon emissions without a steep learning curve in terms of acceptance,” he adds. “Whether they’re built on an X, L or B series platform, these new unified products will have 80 percent detail detail and look and feel familiar to customers and technicians.The Cummins Hydrogen Internal Combustion Engine (ICE) is being tested.The Cummins Hydrogen Internal Combustion Engine (ICE) is being tested.Cummins

“Product architecture, engine capacity and even maintenance intervals are designed using the same parts and components where possible,” White says. “It makes these products an economically viable, scalable and environmentally friendly solution for the planet that can be made today. They will be easy to integrate into existing truck models and they will provide much lower costs associated with training technicians and retail locations. ”

Geography plays a key role in choosing technology. “We know that the acceptance curves will vary depending on the application in the market, region, country, even state and city,” he adds. “Technology that works for one app may not be the right choice for another.”

Internal combustion engines have been around for a long time and the infrastructure for their production is well established. “The initial cost of these engines will be much lower than switching to fully electric or fuel cell options,” says Amy Burger, vice president of North America On Highway. “It’s very important to lower the entry barrier for fleets that want to adopt emission reduction technologies today.”

Whenever there are significant changes in the transmission and its dimensions, it can lead to the fact that the OEM will have to make significant investments. “These engines will also give additional benefits to our truck partners,” says Burger. “The architecture and volume of these engines will be similar to all existing product platforms. This will make it easier for OEMs to integrate different fuel types into the same truck chassis. This means lower costs associated with redesigning the car and any corresponding changes to the production line. This will minimize the cost of technicians and training, as well as the re-equipment of service areas.
