Allison Transmission has successfully integrated the Allison 4000 Series™ transmission with a Class 8 truck equipped with a Hydrogen Internal Combustion Engine (H2-ICE) showcased by Southwest Research Institute at SAE International's Commercial Vehicle Engineering Congress in Schaumburg, Illinois. The H2-ICE vehicle on display surpasses the EPA/CARB 2027 and Euro 7 emissions standards, demonstrating superior emissions control capabilities. Ryan Milburn, Vice President of Product Engineering at Allison Transmission, highlights the importance of internal combustion engine powertrain solutions in advancing towards ultra-low emissions. He emphasizes the flexibility of Allison's transmissions, including the fuel-agnostic feature that enables seamless integration with different fuel sources like gasoline, natural gas, propane, and hydrogen, while ensuring durability and reliable performance. The truck integrated with the H2-ICE engine was initially unveiled at the 2024 ACT Expo and is part of a broader initiative by Southwest Research Institute's H2-ICE Consortium. This consortium, established in November 2022, aims to showcase the potential of hydrogen-fueled internal combustion engines in reducing carbon emissions in the transportation sector. Vehicles powered by H2-ICE engines achieve a remarkable 99.7% reduction in CO2 emissions compared to traditional diesel engines, positioning them as Zero CO2 Emissions Vehicles under future environmental regulations in the U.S. and Europe. Allison's automatic transmissions, with features like power shift technology and torque converter, address the challenges associated with alternative fuels by enhancing startability, drivability, and overall productivity. The company's offerings support sustainability goals without compromising performance or reliability. The integration of Allison's transmission with the H2-ICE truck signifies a significant step in advancing emission control technology and promoting sustainable transportation solutions. The initiative reflects a collaborative effort involving industry leaders to drive innovation and reduce the environmental impact of the transportation sector.
