Volvo’s Latest Semi Truck Engine Upgrade: Wavy Pistons Deliver More Torque
Volvo’s Innovation in Trucking
When we think of iconic American semi trucks, Volvo stands out as a major player globally. With a history of innovation since its first truck in 1928, Volvo continues to push boundaries with its new VNL – a model that is 90% revamped and incorporates cutting-edge technology to boost efficiency by 10% compared to its 2015 predecessors.
The Power Behind the VNL
The new VNL boasts six cab configurations, four trim levels for both interior and exterior, and three versions of the D13 inline-six engine generating an impressive 1,850 lb-ft of torque. Volvo boldly claims a remarkable 8.5 mpg at 85 mph, setting a new standard in the world of heavy-duty trucks.
The Science Inside the Engine
What truly sets the new VNL apart is its innovative waved pistons. These pistons, first introduced in 2016, are meticulously designed to optimize combustion efficiency. By utilizing ridges on the piston crown and strategically positioned fuel injector nozzles, Volvo engineers have created a system that significantly improves fuel economy and reduces soot emissions.
Turbocharged Efficiency
In addition to the revolutionary piston design, Volvo’s D13 engine features a smaller turbo that boosts torque at lower RPMs, enhancing fuel economy with every drop in revolutions. Moreover, the D13 incorporates a turbo compounder, a technology that dates back to World War II, to harness energy typically wasted through the exhaust.
Conclusion
Volvo’s wave piston innovation represents a significant leap in semi truck engine efficiency, showcasing the brand’s commitment to sustainable and high-performance engineering. With a blend of advanced technology and thoughtful design, the new VNL sets a new standard for heavy-duty trucks on the road.

2. What is the significance of the turbo compounder in Volvo’s D13 engine?
The turbo compounder helps reclaim energy that would typically be lost through the exhaust, further enhancing the engine’s efficiency and performance.
3. How does Volvo’s new VNL differ from its previous truck models?
The new VNL is 90% revamped and incorporates advanced engineering techniques like the waved piston design and turbo compounder to achieve a 10% increase in efficiency compared to Volvo’s 2015 trucks.# Article Headline: Volvo Trucks Introduces Innovative Turbo Compound Technology
Introduction
Volvo Trucks has recently introduced an innovative technology known as Turbo Compound, which has been in development since the 1950s but only gained mainstream viability in the last two decades. This technology features a compounder, an additional turbine downstream of the turbo’s turbine, which is mechanically connected to the crankshaft to return power. Volvo’s implementation includes a fluid coupler to control speed and both components are insulated to conserve heat energy before exhaust gases enter the optimized emissions after-treatment system.
All-Electric Drivetrain and Future Possibilities
The latest Volvo VNL model is now available with an all-electric drivetrain option. Moreover, Volvo has announced plans to offer the VNL with a hydrogen fuel cell or engines capable of utilizing renewable diesel. The level of customization available through Volvo’s configurator for these trucks is impressive, catering to operators who rely on these vehicles for their livelihood and spend extended periods on the road.
Conclusion
Volvo Trucks’ Turbo Compound technology represents a significant advancement in the trucking industry, enhancing performance while also focusing on environmental sustainability. The introduction of all-electric drivetrains and the potential for hydrogen fuel cell integration demonstrate Volvo’s commitment to innovation and meeting the evolving needs of the market.
