PERC Debuted New Propane Direct-Injection Fuel System at ACT Expo

Stanadyne, Katech and the Propane Education & Research Council (PERC) developed a new propane direct-injection fuel system that debuted at the Advanced Clean Transportation (ACT) Expo April 28-May 1 in Santa Monica, California.

This system combines Stanadyne’s direct-injection fuel pump with vapor lock technology and injector system with Katech’s vapor lock inhibitor to create the industry’s first medium-duty engine capable of delivering propane autogas up to 200-bar pressure directly into the combustion chamber. Integrated into the Chevrolet Silverado’s 6.6-liter V8 L8T engine, the system produces 401 horsepower, 464 pound-feet of torque and enables a towing capacity of up to 17,370 pounds.

“The test engine/vehicle required only minimal modifications,” says Srinu Gunturu, chief engineer at Stanadyne. “With our newly developed LPG direct-injection pump and injectors, the system demonstrates strong potential for cost-effective scalability and broad commercialization. This technology not only reduces emissions but also makes clean propulsion more accessible for medium- and heavy-duty vehicles where electrification remains a challenge.” Learn more…
