Cummins unveils new engine platform with low- or zero-carbon fuel capability

Cummins Inc. recently showcased its latest engine platform that features a 15L fuel-independent design capable of utilizing hydrogen, natural gas, and advanced diesel fuel options with low- or zero-carbon emissions. The advanced engine is engineered to expedite the decarbonization process of heavy off-road vehicles.

The innovative engine is an eco-friendly advancement that represents the future of diesel engines, with greater power and less environmental impact. Its exceptional power density establishes a benchmark for heavy-duty performance in significant off-road operations, such as:

  • excavators,
  • wheel loaders,
  • drill rigs,
  • road levelers,
  • milling machines,
  • dump trucks,
  • and air compressors.

The equipment’s ingenious design ensures less weight while maximizing engine durability, even under the most challenging working conditions.

The 15-liter platform architecture of the fuel-independent engine utilizes a shared base engine and cylinder heads along with fuel systems that are custom-fit to use carbon-free hydrogen or biogas, resulting in a potential 90% reduction in carbon emissions.

  • The hydrogen engine has up to 530 hp (395 kW) and the natural gas engine has up to 510 hp (380 kW).
  • The upgraded diesel version can operate with HVO or biodiesel, with power up to 650 hp (485 kW), making it suitable for the most demanding off-road work cycles.

Antonio Leitao, who is the Vice President of the global off-road engine business, stated that the all-new Cummins platform has taken internal combustion to a whole new level.

“It can meet the future ultra-low emissions standards such as EPA Tier 5 and EU Stage 6 and can use low or zero carbon fuels to help build and quarries on a lower-cost decarbonizing path.”

He further added that the 15-liter unit has a significantly increased power density and a more compact size, providing equipment manufacturers with the ability to do more with their machines. Their future goal is to offer the same independent capability for the next generation of their current 6.7-liter and 9-liter engine platforms.
