Balancing power & efficiency at every speed
Garrett’s latest generation Variable Geometry Turbo DAVNT (Double Axle VNT) turbocharger is valued in Commercial Vehicles for its ability to increase fuel efficiency as well as engine power density while meeting emissions through Exhaust Gas Recirculation (EGR) control.
Variable Geometry Turbo DAVNT (Double Axle VNT) turbos, available in different sizes, are especially suited to diesel engines with displacements from 2.5L to 15L – from small delivery vans to large highway trucks and off-highway equipment.
Commercial Vehicle DAVNT (Double Axle VNT)
Turbocharger Key Features
The Variable Geometry (VNT) Turbo mechanism in DAVNT, just as in their passenger vehicle counterparts, regulates the exhaust gas flow in direct response to the engine requirements through a row of movable vanes positioned around the inlet of the turbine wheel. These turbine nozzle vanes are supported by two axles for enhanced reliability and durability – above 1.2 million km life cycles. Garrett’s patented pressure balance channels exhaust gas to both sides of the vanes – thereby preventing strong axial loading and reducing friction and wear while enhancing controllability at the same time.
