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, according to the company. 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. The 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 company adds. 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,” says Tom Patterson, vice president of transportation for PSI.

PSI provides solutions to global original equipment manufacturers and end-user customers within the energy, industrial and transportation end markets.

The company develops and delivers powertrains for medium-duty trucks and buses, including school and transit buses, work trucks, terminal tractors and various other vocational vehicles. In addition, PSI develops and delivers power systems that are used worldwide in stationary and mobile power generation applications supporting standby, prime, demand response, microgrid and cogeneration power applications, as well as industrial applications that include forklifts, agricultural and turf, arbor care, industrial sweepers, aerial lifts, irrigation pumps, ground support and construction equipment.
