Allison Transmission integrated the Allison 4000 Series transmission with a Class 8 truck equipped with a Hydrogen Internal Combustion Engine (H2-ICE), which was displayed by Southwest Research Institute at SAE International’s Commercial Vehicle Engineering Congress. The 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 (ICE) powertrain solutions can and will play in moving the industry closer to ultra-low emissions,” said Ryan Milburn,vice-president, 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.”
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.
