Cummins – AccelerateZ: Transient response solutions for zero emissions ICE applications
Boosting hydrogen engine efficiency & cutting emissions in off-highway vehicles through advanced air handling and E-Turbo technologies.
Cummins is driving innovation in hydrogen engine technology to support the transition for zero-emission off-highway vehicles. This project focuses on enhancing efficiency, improving transient response, and reducing NOx emissions further in hydrogen internal combustion engines (H2-ICE) through improved air handling systems. Successfully enhancing performance with advanced turbocharging solutions such as Electric Turbo (E-Turbo) and other novel boosting solutions will solve the transient performance challenges and reduce NOx emissions further for H2-ICE within off-highway vehicles. This will assist with further adoption of hydrogen engines as a viable alternative to non-renewable fuels, cutting CO2 emissions globally.
Project highlights:
– Development and testing of two air-handling systems: a cost-effective PATS and a high-performance E-turbo system.
– Development of product offerings, sourcing TRL5 intent hardware, ensuring feedback on manufacturability from the supply base and assembly of test hardware, including pass-off testing for prototypes.
– Integrating validated systems into an ICE engine and running industry-standard duty cycles (NRMM duty cycle and emission simulation work) to quantify transient performance improvements (motor, PE and complete system testing).
