Wood Dale, Ill.-based Power Solutions International, or PSA, which designs, engineers and manufactures engines and power systems, has received certification for its new 8.8-liter ultra-low nitrogen oxide (NOx) emission propane engine for the transportation market. Both the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) have certified the engine.
Produced in collaboration with Navistar’s IC Bus brand, the engine is certified to a NOx emission standard of 0.02 grams per brake horsepower (g/bhp-hr), making it one of the cleanest propane engines available on the market, the company said. The 8.8-liter engine is certified beyond the EPA’s strictest emission standards and exceeds CARB’s optional low NOx standard for heavy-duty engines.
