Volvo Adds Turbo Compounding for More Engine Power and Efficiency

Volvo Trucks North America is adding a turbo compounding option for the Volvo D13 engine, with the intent of bringing more power and fuel efficiency to the engine.

Here’s what’s special: By converting wasted heat energy, the 13-liter D13 with turbo compounding, according to Volvo, “improves fuel efficiency by up to 6.5 percent, while also delivering up to 100 extra lb.-ft. of torque for improved performance.”

“The Volvo D13 with turbo compounding offers real-world benefits to owners and drivers,” said Gӧran Nyberg, president of Volvo Trucks North America.

Turbo compounding increases fuel efficiency by converting wasted heat energy from the exhaust into useable mechanical energy that is returned as extra torque to the crankshaft of the engine.

“The D13 with turbo compounding is a perfect partner for our popular XE – eXceptional Efficiency – downspeeding package,” said John Moore, Volvo product marketing manager – powertrain. “It’s a win-win for fuel efficiency and performance, as downspeeding increases the energy in the exhaust, which in turn boosts the efficiency of the turbo compounding unit and reduces engine friction at lower cruise rpm’s. This engine will allow all downspeeding driveline packages to now cruise at engine speeds that are 100 rpm lower than before while at the same time offering more torque to maintain performance.”

The Volvo D13 with turbo compounding will be available in two HP ratings – 425 and 455 – in combination with three torque management packages – XE- Economy, XE-High-Torque and XE-Adaptive Gearing – giving customers flexibility to achieve improved fuel efficiency. The D13 with turbo compounding optimizes fuel efficiency for steady state, long-haul applications where downspeeding drivelines thrive.
