PFDI uses two injectors per cylinder—one mounted in the intake port where air enters the cylinder and one positioned inside the cylinder—work together to improve power output and efficiency over a wide variety of engine loads. For example, in part-load operation, the indirect injection can supplement the direct injection to improve fuel economy.

Ford uses the dual-injection PFDI system on its new 3.3L Ti-VCT V6 and its enhanced 5.0L Ti-VCT V8 for 2018. In the 5.0L powerplant, PFDI increases the compression ratio to 12:1 and helps deliver 10 more hp and 13 lb-ft of additional torque.

(Ford also offers PFDI in its new second-generation 2.7L EcoBoost on the 2018 F-150. Earlier post.)

The 2018 F-150 is only the beginning of P-PFDI technology for Alliance. AAG engineers expect the P-PFDI engine to continue growth within the larger vehicle markets.

We plan to be prepared for the advancement in OEM technology with the complementary propane autogas conversion technology. Propane autogas is the most popular alternative fuel world-wide, proven in more than 28 million vehicles, and we must always be prepared to meet the demand of fleets throughout the country.

—Ed Hoffman, President of Blossman Services, Inc.

Stephen Holland, Director of Engineering for Blossman Services, Inc. explained that his team noticed a major shift in OEM technology several years ago as manufacturers began to implement PFDI engines in small cars.

PFDI is a fairly complicated technology, and we knew it was only a matter of time before PFDI became widespread, including implementation into big trucks. It was important for us to begin engineering an autogas solution quickly. We were prepared with a conversion system as soon as Ford introduced the first PFDI commercial truck. We know that PFDI will continue to grow, and we will be ready for the next class of vehicles as they come to market.

AAG’s platform specific engineered P-PFDI conversion system allows fleets to utilize autogas and experience top performance with the following features and benefits:

• Reliability: The new autogas PFDI system provides performance fleets can depend on in extreme weather conditions. There are no cold start issues, nor hot weather complications.

• Emissions Reduction: Autogas PFDI technology significantly reduces tailpipe emissions, most notably include CO₂, CO, and NO_x.

  The tailpipe emissions on the 3.3 liter engine puts this vehicle in the same emissions class as a Hyundai Elantra or Subaru Outback. The 5.0 liter engine is in the same emissions class as the Chevy Volt and the Toyota Yaris.

• Proven OE hardware: The P-PFDI conversion system is an adaptation of AAG’s proven technology that is currently utilized on more than 100,000 vehicles globally with demonstrated success.

• Support: AAG provides an industry leading 5 year, 100,000 mile warranty supported by a trained nationwide service network.
