PSI Attains Certs for Off-Road Propane and Natural Gas Engines


Power Solutions International Inc. (PSI), an Illinois-based company that designs and manufactures alternative fuel engines, says it has received certification from the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) for its 2.0- and 2.4-liter propane and natural gas systems.

The approvals cover off-road, spark-ignited industrial engines that use ‘controls, diagnostic and service platforms common to PSI's entire product line,’ the company says. PSI upgraded certain components to improve the durability of the valvetrain, including premium valve seat inserts that are intended to extend the valvetrain life to beyond 10,000 hours when operating on gaseous fuels. Also, premium camshaft and balance shaft belts extend the service interval to 5,000 hours for these components.

‘These certified engines will support industrial OEMs in the process of compliance and help their customers meet and exceed emission regulations for the future,’ says Gary
Winemaster, CEO of PSI.
