Fast Follow-Up to PSI’s Powertrain Integration Acquisition

Power Solutions International said Tuesday that it’s acquired the electronic fuel-injection system manufacturer Bi-Phase Technologies, formerly a privately held subsidiary of Schwan Food.

Eagan, Minn.-based Bi-Phase Technologies designs and manufactures electronic fuel-injection systems allowing gasoline engines to be fueled by propane autogas.

After developing a successful liquid propane fuel-injection prototype in 1994, PSI says, Bi-Phase was purchased by Schwan in 1999 so the company could use the technology on its fleet of propane-powered home-delivery trucks. Approximately 70% of Schwan’s Home Service fleet of 4,500 delivery trucks runs on liquid propane using Bi-Phase systems.

EPA and CARB Certifications

Bi-Phase’s patented dedicated multi-port systems enable propane to be injected in a liquid state, which eliminates the need for a vaporizer or regulator, improves cold start performance, and reduces backfires. Bi-Phase systems have achieved U.S. EPA and California Air Resources Board certifications for several popular engines, including the General Motors 6.0-liter and PSI’s 8.8-liter units.

Alkane Truck's new propane-fueled Class 7s are to be price-competitive with conventionally fueled vehicles.

“Bi-Phase makes a market-leading propane system that is a key component in our propane engines,” PSI chairman and CEO Gary Winemaster said in a release.

“With our manufacturing and supply chain knowledge, we see a unique opportunity to integrate Bi-Phase systems into many more products,” he said.

School Buses, Alkane Trucks, Capacity Yard Tractors

“We expect this acquisition to further strengthen our partnership with GM, since we can apply this technology to a wider range of applications.”

PSI says its uses the Bi-Phase fuel-injection system on the recently launched Navistar IC CE Series propane school bus, a new Alkane truck (F&F, April 5, 2014), and the Capacity TJ5000 LP terminal tractor.

PSI just announced its acquisition of engine manufacturer Powertrain Integration (F&F, May 11), which it says “provides additional fuel system options, which will further strengthen the company offerings and opportunities.”

‘Best on the Market Today’

Schwan is selling Bi-Phase as part of a strategy to focus on its core food businesses, brands and services, PSI says.

“We strongly believe that the propane conversion systems produced by Bi-Phase are the best on the market today,” said Schwan CEO Dimitrios Smyrnios says in the PSI announcement. “Ultimately, we know that PSI will have the expertise to bring new levels of success for Bi-Phase’s alternative fuel systems.”

As a part of the agreement, PSI is to continue to provide Schwan’s fleet with Bi-Phase systems.
