Allison Transmission recently announced the integration of the Allison 4000 Series transmission with a Class 8 truck equipped with a hydrogen internal combustion engine displayed by Southwest Research Institute at SAE International’s Commercial Vehicle Engineering Congress in Schaumburg, Illinois.
The H2-ICE vehicle demonstrates emissions control capable of outperforming EPA/CARB 2027 and Euro 7 criteria pollutant emissions standards.
"The integration of our Allison 4000 Series in the H2-ICE vehicle demonstrates the critical role internal combustion engine powertrain solutions can and will play in moving the industry closer to ultra-low emissions,” said Ryan Milburn, VP of product engineering, Allison Transmission. “From our fuel-agnostic conventional transmissions to electric hybrid and fully electric propulsion systems, Allison proudly offers the power of choice for customers aiming to achieve sustainability goals without compromising performance or reliability."
Allison said its fully automatic transmissions are fuel-agnostic and offer optimal integration with any fuel source, ensuring durability and reliability without sacrificing fleet productivity and efficiency. To compensate for the lower power and slower engine response associated with alternative fuels, Allison’s power shift technology and torque converter improve startability, drivability, and overall productivity.
Initially unveiled at the 2024 ACT Expo in Las Vegas, the truck is part of a broader initiative led by SwRI through its H2-ICE Consortium. Launched in November 2022, the consortium aims to demonstrate the potential of hydrogen-fueled internal combustion engines for decarbonizing the transportation industry.
