PSI, an American engine manufacturer member of the Weichai group, and HD Hyundai Infracore have signed an agreement with two clear objectives: to strengthen their commercial presence in North American markets and to develop a common engine platform that will become, in its own way, “agnostic”. Unlike other manufacturers (see Cummins and FPT Industrial), there is no mention of hydrogen versions right now, but rather of different gaseous fuels starting from the Diesel engine block.

The agreement between HD Hyundai Infracore and PSI in detail

Power Solutions International, (PSI) announced at the end of August a new cooperative agreement with HD Hyundai Infracore (HDI). This collaboration adds a robust line of Tier 4 and Euro Stage V diesel engines to PSI’s existing range of industrial spark-ignited power solutions.

Under the terms of the agreement, Power Solutions International will market, develop, and distribute HDI’s industrial EPA Tier 4 and Euro Stage V diesel engine offerings throughout North America, as well as provide customers with integration services and turn-key power units. The agreement also includes the gasification development of certain HDI diesel engines, offering customers a “common block” solution for multiple fuel types, including LPG, Diesel, Gasoline, and Natural Gas.
