Power Solutions International, Inc.
A maker of emission-certified engines and integrated power systems, Power Solutions International builds the engines that power forklifts, construction machinery, agricultural equipment, and generators. Founded in 1985 by the Winemaster brothers, the company was long known as "The W Group" before renaming itself Power Solutions International in 2011. Its engines are famously "fuel-agnostic" — the same base design can run on natural gas, propane, gasoline, or diesel, letting customers pick the fuel that suits them.
