Arizona Tribune - American Power Group Announces $250,000+ of S4000 Stationary Dual Fuel System Orders

ALGONA, IA / ACCESS Newswire / June 1, 2026 / American Power Group Corporation ("APG") (OTC PINK:APGI) the leading U.S. based dual fuel diesel engine conversion technology company announced today that it has received approximately $250,000+ of stationary dual fuel conversion orders from its network of stationary certified dealer/installers. APG's stationary/off-road dual fuel installation base has exceeded 1,500 installations since 2010 and surpassed an estimated 25 million cumulative run hour milestone in high-horsepower applications which attests to the reliability of APG's dual fuel solution.

Chuck Coppa, APG's CEO/CFO stated, "We are pleased to see a measurable increase in quotation activity by our stationary certified dealer/installer network over the past several months. Despite the recent dramatic rise in gas and diesel prices, oil/gas field service companies remain cautious and thoughtful in their efforts to re-establish drilling activities which is why APG's S4000's reputation for the high up-time and the lowest TCO in the dual fuel sector is so appealing."

Mr. Coppa added, "In addition to these recent stationary dual fuel conversion orders, we currently have an additional $2 million+ of outstanding customer quotes spread among several of our stationary dealer/installers and are working diligently to convert these quotes into actual orders. Displacing up to 65% of the diesel fuel with natural gas has an enormous impact on operating costs, emissions and of course carbon footprint for operators using our technology."

APG's S4000 dual fuel technology seamlessly introduces natural gas from renewable, fossil or treated field gas into the induction system of a diesel engine, displacing up to 65% of the diesel fuel. The S4000 system does not change any of the OEM diesel engine components, maintaining base engine temperature and pressure parameters of the OEM engine. In

Generator power ratings from 100kW to 12MW have been successfully converted to APG's dual fuel technology on a wide array of OEM diesel engine platforms including:

*Caterpillar *Cummins *MTU *Detroit Diesel *MAN B&W

*Kohler *Perkins *John Deere *Komatsu *Wartsila

*Isuzu *Nigata *Isuzu *Daihtsu
