PSI, Navistar showcase propane-powered bus engine

Power Solutions International Inc. (PSI) displayed its 8.8-liter engine during the STN Expo conference and trade show July 30 in Reno, Nevada. The engine, powered by gasoline and propane, was featured by Navistar’s IC Bus.

The 8.8-liter engine, PSI says, provides a fully integrated drop-in engine solution that offers power and performance, emissions certification, fuel flexibility and compatibility with Allison transmissions. IC Bus first produced a bus powered by PSI’s 8.8-liter propane engine in 2015, and the first bus with PSI’s 8.8-liter gasoline engine was released in 2018, PSI says.

“We are excited to continue to support our customer IC Bus, who has been a great partner,” says John Miller, PSI CEO.

PSI’s 8.8-liter engine also powers the 2020 model year of FCCC’s S2G work truck vehicle, which pairs FCCC’s S2 chassis with a factory-installed propane autogas engine. The chassis is designed for commercial market applications, including pickup and delivery, student transportation and municipalities.

PSI designs, engineers and manufactures emissions-certified, alternative-fuel power systems. It provides integrated turnkey solutions to global original equipment manufacturers in the industrial and on-road markets. The company’s in-house design, prototyping, engineering and testing capacities allow it to customize clean, high-performance engines that run on a wide variety of fuels, including natural gas, propane, biogas, gasoline and diesel.

Sponsored by School Transportation News, the STN Expo welcomes transportation professionals from across the country who want to learn about the latest training, products and services in the industry. The event features speakers, workshops and educational events as well as more than 130 exhibitors, including several of the country’s largest bus OEMs.
