A multi-state propane supplier is poised to introduce a dual-fuel system for Class 8 diesels that promises significant savings with a relatively modest investment in equipment and a payback in under two years.

Blossman Services, North Carolina, is waiting on final governmental approval for a “blended fuel” system that injects varying amounts of propane autogas to replace diesel fuel in heavy duty truck engines. The system has been certified by the federal Environmental Protection Agency for a 14-liter Detroit Diesel Series 60, said Jessie Johnson, vice president of marketing.

The engine has been running for six months in a road tractor hauling auto parts between Pennsylvania and upstate New York, he said. In Canada there already are 150 to 200 trucks running with the system because EPA certification is not needed there, Johnson said.

Next to be certified is Volvo’s D13, which several interested fleets are running, he said. Mack’s MP8 version of the 12.8-liter diesel is also likely to be certified.

The system is certified for retrofitting onto existing diesels with at least 185,000 miles, which EPA calls intermediate useful life under its maintenance requirements, said Brent Kiomall, Blossman’s applications engineer. All emissions equipment must be retained, but later testing might show that some could be modified or removed.

Certification for new engines might follow with cooperation from truck and engine builders, Johnson said. Blossman expects to begin selling the first retrofit systems in October.

The system is from Prins, a Dutch company, obtained through BL Energie of Canada, Blossman’s partner in this venture, Johnson said.
