To power the major launch of the all-new Volvo VNR, Volvo Trucks North America has launched the new Volvo D13 VGT (Variable Geometry Turbo) engine. The new Volvo D13 VGT engine will be standard in the all-new Volvo VNR, and customers will also be able to select it in the all-new Volvo VNL day cab. The new D13 VGT engine builds on the game-changing improvements launched with the all-new D13 Turbo Compound engine, which is standard on the all-new Volvo VNL.
Focusing on fuel efficiency and durability, Volvo Trucks has made key enhancements to the D13 VGT engine, including:
- Advanced Piston Design: The improved seven-wave piston optimizes air and fuel mixture control, resulting in more efficient combustion. The piston height has been decreased and paired with a longer connecting rod to minimize cylinder sidewall pressure, reducing friction and enhancing overall performance. In addition to improving the combustion process, the seven-wave design allows for greater heat dispersion across the top of the piston head, lowering the overall temperature and reducing NOx output.
- Enhanced Fuel Injector: Smaller needle control valves in the fuel injectors provide precise and rapid control over the fuel flow rate, leading to improved fuel atomization, better combustion efficiency, and enhanced engine performance.
- Variable Displacement Oil Pump: This innovative pump dynamically adapts to the engine’s oil pressure demands, minimizing parasitic losses, reducing wear and tear, and improving efficiency.
The new Volvo D13 VGT engine also utilizes the 24-volt electrical system, which Volvo first introduced in North America with the all-new Volvo VNL. The 24-volt electrical architecture allows for lighter components and can prolong the life of those components due to the system’s lower amperage.
“As we continue to innovate and improve our powertrain offerings, the Volvo D13 VGT engine launch marks another significant step forward in our commitment to fuel efficiency and sustainability,” said Peter Voorhoeve, president of Volvo Trucks North America. “Fuel costs remain the second highest expense for fleets in North America, and our powertrain improvements represent an up to 3 percent fuel efficiency improvement over our previous generation engine. The D13 VGT engine is built to deliver the performance and reliability our customers expect while contributing to a cleaner, more efficient future.”
The Volvo D13 VGT engine is now available for order in the all-new Volvo VNR and VNL models. Customers can choose from engine options offering 405, 425, 435, and 455 HP, with torque ratings ranging from 1450 to 1850 lb. ft. Customers purchasing the all-new Volvo VNR when orders begin will also have the option to select the D13 Turbo Compound engine, which is well suited for fleets using the VNR in a highway application.
Fleet operators can learn more and place orders by visiting their nearest Volvo Trucks dealership, where the sales staff have been fully trained on the engine’s capabilities.
