Power Solutions International – other road engines: the collective page of gas and LPG engines outside the named ranges, 6.0 and 8.8-litre base, 180 to 324 hp, CNG, LPG and petrol versions
This page gathers the Power Solutions International engines the register could not assign to a named range. PSI, based in Illinois, builds combustion engines for natural gas, LPG and petrol operation on a 6.0 and 8.8-litre block base; the EPA engine-family codes such as PPSIE08.8LPG or HPSIE06.0CNG encode displacement (08.8 for 8.8 litres, 06.0 for 6.0 litres) and the fuel in the CNG, LPG or GAS code.

The register lists here 14 versions with 180 to 324 hp rated output at 2,600 to 4,900 rpm, consistently with sequential fuel injection, model years from 2015 to 2023, maximum torque from 293 to 565 Nm at 1,500 to 4,315 rpm. Natural gas, petrol, LPG, compressed natural gas and propane are recorded as fuel; all certified versions apply to the US market.
PSI chiefly supplies body builders and fleet operators who rely on alternative fuels for city buses, sweepers and light to medium commercial vehicles, competing with Cummins Westport and other gas-engine makers.
On a used purchase, operating hours, the condition of the spark plugs and the gas system including the pressure regulator, the tightness of the gas lines, the condition of the catalyst, and on CNG versions the inspection deadlines of the gas tanks all count; parts and service run through the PSI dealer network. On engines converted from a petrol base, the wear pattern on the valve seats is also worth checking, since gaseous fuels place different demands on them than petrol does.
