Volvo Trucks’ D13 Turbo Compound engine now standard on all VNL models; 6% better fuel economy over 2020 engine

Green Car Congress

Excess heat and pressure from the exhaust gas are recaptured by the turbo-compound unit. The Volvo integrated driveline then uses extreme downspeeding to maintain road speed at lower RPM, saving even more fuel. Dynamic torque integrates seamlessly with all three available drive modes: performance, economy, and extra economy.

BorgWarner suggests Valve-Event Modulated Boost system can offer 6-17% fuel economy benefit over already downsized and turbocharged engines

Green Car Congress

The VEMB system uses a concentric camshaft, blow-down manifold and scavenge manifold to separate the exhaust event into two phases: high-energy blow-down to the turbo without pumping losses, and high-hydrocarbon scavenge to the EGR system. The company also has demonstrated the potential to increase compression ratios by 1.5
