Power Solutions International Receives Off-Highway Certification for Low-Emission 8.8L Engine

WOOD DALE, Ill., Dec. 06, 2021 -- Power Solutions International, Inc., a leader in the design, engineering and manufacture of emissions-certified engines and power systems, today announced it received non-road certification for its 8.8-liter propane engine from the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB). The certification allows the propane-powered engine’s use in mobile, non-road applications.

The non-road certification allows PSI to bring the 8.8-liter engine more rapidly to market for customers. Target applications include terminal tractors and other non-road mobile equipment for ports and other transport hubs. The non-road engine – available in the market now – is part of PSI’s efforts to expand its near-zero product line. This non-road engine shares the same technology as PSI’s ultra-low NOx 8.8-liter propane engine previously approved for heavy-duty on-road applications. The non-road engine’s near-zero NOx level makes it one of the cleanest engines available in the market. The engine offers 265 horsepower with 553 lb-ft of torque.

“Our 8.8-liter propane engine is a proven solution that will produce similar results for non-road applications as it does for heavy duty on-road uses,” PSI vice president – transportation Tom Patterson said.
