Mack Trucks announced today that the 2017 Mack MP 8 engine with turbo compounding is now available for order, offering highway customers increased fuel efficiency.
“The new MP8 engine with turbo compounding is just one of the many engine upgrades Mack made to further enhance fuel efficiency for customers,” said Roy Horton, Mack director of product strategy. “The turbo compounding system enables an improved operating range and allows a truck to hold top gear when cresting a hill, even with the engine rpm decreasing.”
Available exclusively with Mack’s Super Econodyne downspeeding package, the MP8 with turbo compounding converts wasted energy from the exhaust into mechanical energy that is fed back to the engine. The system adds up to 50 additional horsepower, improving fuel efficiency by up to 8.8 percent. The additional power generated by the turbo compounding system allows the engine to maintain full torque as low as 900 rpm.
Several of the revised components and technologies found on Mack’s 2017 MP series engines – including the patented wave piston, turbo compounding and the common rail fuel injection system – were derived from research and development work associated with the U.S. Department of Energy’s SuperTruck program.
The SuperTruck program, a cost-shared, public-private partnership, aims to help accelerate the research and development of advanced efficiency technologies to improve the freight-hauling efficiency of heavy-duty Class 8 long-haul tractor-trailer trucks.
Along with its involvement in the SuperTruck program, and now SuperTruck II, Mack also has been involved in several advanced technology projects that have unique features and benefits for specific applications.
