Cummins details potential for internal combustion engine efficiency leveraging fuel-saving innovations
White paper explores cumulative impact of idle reduction technologies
Cummins Inc. (NYSE: CMI) has released a white paper, “Fuel economy and CO2 improvement potential of Conventional ICE powertrains.” The paper details fuel economy innovations that can be implemented in the near-term to improve the efficiency of internal combustion engines (ICE) for fleets. According to Cummins’ experts, idle reduction technologies can provide up to 17% in fuel economy savings.
Growing regulatory pressures and demand from truck operators have created a push for immediate solutions for engine efficiency as low- and zero-emission technologies reach the market. While the end goal is a fully decarbonized product portfolio, the path forward must be practical and adaptable.
“We recognize that there is not a single path to decarbonization and no one solution will meet the needs of everyone,” says José Samperio, Vice President and General Manager for Cummins On-Highway Business. “Cummins is investing in near-term, readily available solutions to drive engine efficiency and affordability for fleets, while also looking ahead to the zero-emission innovations that will be an important part of the future technology mix.”
Cummins offers a portfolio of integrated powertrain solutions with features available for specification including Neutral Idle, Automatic Engine Shutdown (AES) and Stop-Start technology - designed to improve efficiency across the entire vehicle system. Using mature, familiar systems creates the opportunity to minimize waste without compromising drivability or uptime, allowing owners and operators to cut fuel use, costs and emissions. These solutions are not only effective and reliable—they’re already on the road today, with availability varying by truck manufacturer.
By highlighting opportunities for fuel efficiency improvements and cost reductions, the white paper underscores Cummins’ whole-portfolio approach to reducing emissions, embodied in its Destination Zero strategy. Many Cummins customers will continue operating internal combustion engine vehicles for many years and Cummins is focused on making those engines as clean and efficient as possible, laying the foundation for a more sustainable future.
